The highway system of the United States is a network of interconnected state, U.S., and Interstate highways. Each of the fifty states, the District of Columbia, Puerto Rico, American Samoa, Guam, the Northern Mariana Islands, and the U.S. Virgin Islands own and maintain a part of this vast system, including U.S. and Interstate highways, which are not owned or maintained at the federal level.


Interstate Highways have the highest speed limits and the highest traffic numbers. Interstates are numbered in a grid: even-numbered routes for east–west routes (with the lowest numbers along Mexico and the Gulf of Mexico), and odd-numbered routes are north–south routes (with the lowest numbers along the Pacific Ocean). Three-digit Interstates are, generally, either beltways or spurs of their parent Interstates (for example, Interstate 510 is a spur into the city of New Orleans, Louisiana, and is connected to Interstate 10).


U.S. Numbered Highways are the original interstate highways, dating back to 1926. U.S. Highways are also numbered in a grid: even numbered for east–west routes (with the lowest numbers along Canada) and odd numbered for north–south routes (with the lowest numbers along the Atlantic Ocean). Three-digit highways, also known as "child routes," are branches off their main one- or two-digit "parents" (for example, U.S. Route 202 is a branch of U.S. Route 2). However, US 101, rather than a "child" of US 1, is considered a "mainline" U.S. Route.


State highways are the next level in the hierarchy. Each state and territory has its own system for numbering highways, some more systematic than others. Each state also has its own design for its highway markers; the number in a circle is the default sign, but many choose a different design connected to the state, such as an outline of the state with the number inside. Many states also operate a system of county highways.


Scenic byways can be designated over any classification of road in the United States. There are the National Scenic Byways, National Forest Scenic Byways and Bureau of Land Management Back Country Byways at the national level. Most states have their own system for designating byways, some more systematic than others. Native American tribes may designate byways as well.

Image 1State Route 522 (SR 522) is a state highway in the U.S. state of Washington that serves the Seattle metropolitan area. Approximately 25 miles (40 km) long, it connects the city of Seattle to the northeastern suburbs of Kenmore, Bothell, Woodinville, and Monroe. Its western half is primarily an arterial street, named Lake City Way and Bothell Way, that follows the northern shore of Lake Washington; the eastern half is a grade-separated freeway that runs between Woodinville and Monroe. SR 522 connects several of the metropolitan area's major highways, including Interstate 5 (I-5), I-405, SR 9, and U.S. Route 2 (US 2).
The present-day route of SR 522 was built in stages between 1907 and 1965, beginning with the Red Brick Road from Seattle to Bothell, then part of the Pacific Highway and later US 99. The road later became a branch of Primary State Highway 2 (PSH 2) in 1937, and was extended east to Redmond and North Bend. A branch of the Stevens Pass Highway was built to connect PSH 2 in Bothell and Monroe in 1965, and was incorporated into SR 202 after it was designated in 1964. The Bothell–Monroe highway was re-designated as part of SR 522 in 1970, leaving SR 202 on the Bothell–North Bend highway. (Full article...) -
Image 2Interstate 75 (I-75) is a part of the Interstate Highway System that runs from the Hialeah–Miami Lakes line to the Canadian border at Sault Ste. Marie, Michigan. I-75 enters the state from Ohio in the south, north of Toledo, and runs generally northward through Detroit, Flint, and Bay City, crosses the Mackinac Bridge and ends at the border in Sault Ste. Marie. The freeway runs for approximately 396 miles (637 km) on both of Michigan's major peninsulas. The landscapes traversed by I-75 include Southern Michigan farmland, northern forests, suburban bedroom communities, and the urban core of Detroit. The freeway also uses three of the state's monumental bridges to cross major bodies of water. There are four auxiliary Interstates in the state related to I-75, as well as nine current or former business routes, with either Business Loop I-75 (BL I-75) or Business Spur I-75 (BS I-75) designations.
The freeway bears several names in addition to the I-75 designation. The southern segment was called the Detroit–Toledo Expressway during planning in the 1950s and 1960s. Through Detroit, I-75 is the Fisher Freeway or the Walter P. Chrysler Freeway, named for pioneers in the auto industry. Sections on either side of the Mackinac Bridge are the G. Mennen Williams Freeway or the Prentiss M. Brown Freeway, named for politicians who helped get the bridge built. Officially, the entire length is the American Legion Memorial Highway, after the organization of the same name. Various sections carry components of the four Great Lakes Circle Tours in the state.

Image 3M-28 is an east–west state trunkline highway that traverses nearly all of the Upper Peninsula of the U.S. state of Michigan, from Wakefield to near Sault Ste. Marie in Bruce Township. Along with US Highway 2 (US 2), M-28 forms a pair of primary highways linking the Upper Peninsula from end to end, providing a major access route for traffic from Michigan and Canada along the southern shore of Lake Superior. M-28 is the longest state trunkline in Michigan numbered with the "M-" prefix at 290.373 miles (467.310 km). The entire highway is listed on the National Highway System, while three sections of M-28 are part of the Lake Superior Circle Tour. M-28 also carries two memorial highway designations along its route.
Throughout its course across the Upper Peninsula, M-28 passes through forested woodlands, bog swamps, urbanized areas, and along the Lake Superior shoreline. Sections of roadway cross the Ottawa National Forest and both units of the Hiawatha National Forest. Some of the other landmarks accessible from M-28 include the Seney Stretch, Seney National Wildlife Refuge and several historic bridges. (Full article...) -
Image 4Interstate 90 (I-90) is an east–west transcontinental freeway and the longest Interstate Highway in the United States at 3,099.7 miles (4,988.5 km). It begins in Seattle, Washington, and travels through the Pacific Northwest, Mountain West, Great Plains, Midwest, and the Northeast, ending in Boston, Massachusetts. The highway serves 13 states and has 15 auxiliary routes, primarily in major cities such as Chicago, Cleveland, Buffalo, and Rochester.
I-90 begins at Washington State Route 519 in Seattle and crosses the Cascade Range in Washington and the Rocky Mountains in Montana. It then traverses the northern Great Plains and travels southeast through Wisconsin and the Chicago area by following the southern shore of Lake Michigan. The freeway continues across Indiana and follows the shore of Lake Erie through Ohio and Pennsylvania to Buffalo. I-90 travels across New York by roughly following the historic Erie Canal and traverses Massachusetts, reaching its eastern terminus at Massachusetts Route 1A near Logan International Airport in Boston.

Image 5State Route 128 (SR-128) is a 44.564-mile-long (71.719 km) state highway in the U.S. state of Utah. The entire length of the highway has been designated the Upper Colorado River Scenic Byway, as part of the Utah Scenic Byways program. This road also forms part of the Dinosaur Diamond Prehistoric Highway, a National Scenic Byway. Residents of Moab frequently refer to SR-128 as "the river road", after the Colorado River, which the highway follows.
The highway was originally constructed to connect rural cities in eastern Utah with Grand Junction, Colorado, the largest city in the region. Part of the highway was merged into the Utah state highway system in 1931; the rest was taken over by the state and assigned route number 128 in 1933. Today, the highway is used as a scenic drive for visitors to the area. (Full article...) -
Image 6State Route 52 (SR 52) is a state highway in San Diego County, California, United States. It extends from La Jolla Parkway at Interstate 5 (I-5) in La Jolla, San Diego, to SR 67 in Santee. It is a freeway for its entire length and serves as a major east–west route through the northern part of the city of San Diego. The road connects the major north–south freeways of the county, including I-5, I-805, SR 163, I-15, SR 125, and SR 67. SR 52 passes north of the Rose Canyon Fault before traversing Marine Corps Air Station Miramar (MCAS Miramar). East of Santo Road and west of SR 125, the highway goes through Mission Trails Regional Park, a large open preserve. SR 52 is also known as the Soledad Freeway and the San Clemente Canyon Freeway.
Plans for a route between La Jolla and Santee date from 1959, and SR 52 was officially designated in the 1964 state highway renumbering. Construction began in 1966 at the I-5 interchange with Ardath Road leading to La Jolla. It continued with the construction of San Clemente Canyon Road, which was later widened to become SR 52. The freeway was completed east to I-805 in 1970, and was built in two stages from there to Santo Road east of I-15; the last phase was completed in 1988. (Full article...) -
Image 7Maryland Route 36 (also known as MD 36 or Route 36) is a 29.43-mile (47.36 km) state highway located in Allegany County, Maryland, United States. MD 36's southern terminus is at the West Virginia Route 46 (WV 46) bridge in Westernport and its northern terminus at U.S. Route 40 Alternate (US 40 Alt.) near Cumberland. Between Westernport and Frostburg, it is known as Georges Creek Road, and from Frostburg to Cumberland it is known as Mount Savage Road. Like the majority of Maryland state highways, MD 36 is maintained by the Maryland State Highway Administration (MDSHA).
MD 36 serves as the main road through the Georges Creek Valley, a region which is historically known for coal mining, and has been designated by MDSHA as part of the Coal Heritage Scenic Byway. MD 36 is the main road connecting the towns of Westernport, Lonaconing, and Midland in southwestern Allegany County, as well as Frostburg, Mount Savage, and Corriganville in northwestern Allegany County.

Image 8The Kansas Turnpike is a 236-mile (380 km) controlled-access toll road that lies entirely within the US state of Kansas. It runs in a general southwest–northeast direction from the Oklahoma border to Kansas City. It passes through several major Kansas cities, including Wichita, Topeka, and Lawrence. The turnpike is owned and maintained by the Kansas Turnpike Authority (KTA), which is headquartered in Wichita.
The Kansas Turnpike was built from 1954 to 1956, predating the Interstate Highway System. While not part of the system's early plans, the turnpike was eventually incorporated into the Interstate System in late 1956 and is designated today as four different Interstate Highway routes: Interstate 35 (I-35), Interstate 335 (I-335), I-470, and I-70. The turnpike also carries a piece of two U.S. Highways: U.S. Highway 24 (US-24) and US-40 in Kansas City. (Full article...) -
Image 9Interstate 182 (I-182) is an east–west auxiliary Interstate Highway in the U.S. state of Washington. It connects I-82 to the Tri-Cities region and crosses the Columbia River on the Interstate 182 Bridge between Richland and Pasco. I-182 is 15 miles (24 km) long and entirely concurrent with U.S. Route 12 (US 12). It also intersects Washington State Route 240 (SR 240) and US 395.
Business leaders in the Tri-Cities began lobbying for a freeway in 1958 after early alignments for I-82 were routed away from the area. I-182 was created by the federal government in 1969 as a compromise that would directly connect to the Tri-Cities area while allowing other traffic to bypass it. The project would also incorporate an existing proposal to build a bridge between Richland and Pasco at the site of a cable ferry that ran until 1931. (Full article...) -
Image 10Interstate 296 (I-296) is a part of the Interstate Highway System in the US state of Michigan. It is a north–south state trunkline highway that runs for 3.43 miles (5.52 km) entirely within the Grand Rapids area. Its termini are I-196 near downtown Grand Rapids and I-96 on the north side of Grand Rapids in Walker. For most of its length, the Interstate runs concurrently with U.S. Highway 131 (US 131), which continues as a freeway built to Interstate Highway standards north and south of the shorter I-296. The highway was first proposed in the late 1950s and opened in December 1962, but the Michigan Department of Transportation (MDOT) has since eliminated all signage for I-296 and removed the designation from their official state map. The designation is therefore unsigned, but still listed on the Interstate Highway System route log maintained by the Federal Highway Administration (FHWA). (Full article...)

View of the route, 1920
The Ridge Route, officially the Castaic–Tejon Route and colloquially known as the Grapevine, was a two-lane highway between Los Angeles County and Kern County, California, United States. Opened in 1915 and paved with concrete between 1917 and 1921, the road was the first paved highway directly linking the Los Angeles Basin with the San Joaquin Valley (southern Central Valley) over the Tejon Pass and the rugged Sierra Pelona Mountains ridge south of Gorman. Much of the old road runs through the Angeles National Forest, and passes many historical landmarks, including the National Forest Inn, Reservoir Summit, Kelly's Half Way Inn, Tumble Inn, and Sandberg's Summit Hotel. North of the forest, the Ridge Route passed through Deadman's Curve before ending at Grapevine.
The road was originally built as a state highway, a segment of the unsigned Legislative Route 4, before it became signed as part of U.S. Route 99 (US 99) in 1926. The road was then bypassed by the three-lane Ridge Route Alternate to handle increased traffic and remove curves; the Alternate in Los Angeles County was completed in 1933, and Kern County line to Grapevine in 1936. The roadway was widened to a four-lane expressway in 1953 and replaced by an eight-lane freeway, Interstate 5 (I-5) in 1960-70. The portion of the road in the Angeles National Forest was added to the National Register of Historic Places in 1997, by the efforts of retired engineer Harrison Scott. Much of the road has been closed by the U.S. Forest Service; other remnants are used by local traffic. (Full article...) -
Image 12US Highway 41 (US 41) is a part of the United States Numbered Highway System that runs from Miami, Florida, to the Upper Peninsula of the US state of Michigan. In Michigan, it is a state trunkline highway that enters the state via the Interstate Bridge between Marinette, Wisconsin, and Menominee, Michigan. The 278.769 miles (448.635 km) of US 41 that lie within Michigan serve as a major conduit. Most of the highway is listed on the National Highway System. Various sections are rural two-lane highway, urbanized four-lane divided expressway and the Copper Country Trail National Scenic Byway. The northernmost community along the highway is Copper Harbor at the tip of the Keweenaw Peninsula. The trunkline ends at a cul-de-sac east of Fort Wilkins State Park after serving the Central Upper Peninsula and Copper Country regions of Michigan.
US 41 passes through farm fields and forest lands, and along the Lake Superior shoreline. The highway is included in the Lake Superior Circle Tour and the Lake Michigan Circle Tour and passes through the Hiawatha National Forest and the Keweenaw National Historical Park. Historical landmarks along the trunkline include the Marquette Branch Prison, Peshekee River Bridge and the Quincy Mine. The highway is known for a number of historic bridges such as a lift bridge, the northernmost span in the state and a structure referred to as "one of Michigan's most important vehicular bridges" by the Michigan Department of Transportation (MDOT). Seven memorial highway designations have been applied to parts of the trunkline since 1917, one of them named for a Civil War general. (Full article...) -
Image 13Interstate 94 (I-94) is a part of the Interstate Highway System that runs from Billings, Montana, to the Lower Peninsula of the US state of Michigan. In Michigan, it is a state trunkline highway that enters the state south of New Buffalo and runs eastward through several metropolitan areas in the southern section of the state. The highway serves Benton Harbor–St. Joseph near Lake Michigan before turning inland toward Kalamazoo and Battle Creek on the west side of the peninsula. Heading farther east, I-94 passes through rural areas in the middle of the southern Lower Peninsula, crossing I-69 in the process. I-94 then runs through Jackson, Ann Arbor, and portions of Metro Detroit, connecting Michigan's largest city to its main airport. Past the east side of Detroit, the Interstate angles northeasterly through farmlands in The Thumb to Port Huron, where the designation terminates on the Blue Water Bridge at the Canada–United States border.
The first segment of what later became I-94 within the state, the Willow Run Expressway, was built near Ypsilanti and Belleville in 1941, with an easterly extension to Detroit in 1945. This expressway was initially numbered M-112. In the mid-1950s, state and federal officials planned an Interstate to replace the original route of US Highway 12 (US 12). By 1960, the length of I-94 was completed from Detroit to New Buffalo. Two years later, the US 12 designation was dropped from the freeway. Subsequent extensions in the 1960s completed most of the rest of the route, including the remaining sections between Detroit and Port Huron which superseded the routing of US 25. The last segment opened to the public in 1972 when Indiana completed its connection across the state line. Since completion, I-94 has remained relatively unchanged; a few interchanges have been rebuilt, a second span was constructed for the Blue Water Bridge, and, in 1987, a plane crashed on the freeway during takeoff from the airport in Detroit. The routing of I-94 is notable for containing the first full freeway-to-freeway interchange in the United States, connecting to the Lodge Freeway (M-10), and for comprising the first complete border-to-border toll-free freeway in a state in the United States. The highway has one auxiliary route, I-194, which serves downtown Battle Creek, and eight business routes. Various segments have been dedicated to multiple people and places. (Full article...) -
Image 14State Route 78 (SR 78) is a state highway in the U.S. state of California that runs from Oceanside east to Blythe, traversing nearly the entire width of the state. Its western terminus is at Interstate 5 (I-5) in San Diego County and its eastern terminus is at I-10 in Riverside County. The route is a freeway through the heavily populated cities of northern San Diego County and a two-lane highway running through the Cuyamaca Mountains to Julian. In Imperial County, SR 78 travels through the desert near the Salton Sea and passes through the city of Brawley and the Algodones Dunes before turning north on the way to its terminus in Blythe.
SR 78 was one of the original state highways designated in 1934, although portions of the route existed as early as 1900. However, it was not designated east of Brawley until 1959. The freeway section in the North County of San Diego that connects Oceanside and Escondido was built in the middle of the twentieth century in several stages, including a transitory stage known as the Vista Way Freeway, and has been altered several times. An expressway bypass of the city of Brawley was completed in 2012. There are many projects slated to add capacity to the freeway due to increasing congestion in the region. (Full article...) -
Image 15State Route 75 (SR 75) is a 13-mile (21 km) north-south state highway in San Diego County in the U.S. state of California. It is a loop route of Interstate 5 (I-5) that begins near Imperial Beach, heading west on Palm Avenue. The route continues north along the Silver Strand, a thin strip of land between the Pacific Ocean and San Diego Bay, through Silver Strand State Beach. SR 75 then passes through the city of Coronado as Orange Avenue and continues onto the San Diego–Coronado Bay Bridge, which traverses the bay, before joining back with I-5 near downtown San Diego.
The Silver Strand Highway was constructed and open to the public by 1924. What would become SR 75 was added to the state highway system in 1933, and designated Legislative Route 199 in 1935. SR 75 was not officially designated until the 1964 state highway renumbering. The Coronado Bay Bridge opened in 1969, and provided a direct connection between San Diego and Coronado. Since then, various proposals have taken place to relieve commuter traffic between San Diego and Naval Air Station North Island that traverses the city of Coronado. However, none of these proposals have gained support, including an attempt in 2010. (Full article...)

Image 1State Route 101 (SR-101) is a 21.811-mile (35.101 km) long state highway located in the U.S. state of Utah. The route serves as a spur route into the Uinta-Wasatch-Cache National Forest through the cities of Wellsville and Hyrum, with an intermediate intersection with U.S. Route 89 (US-89) and US-91. SR-101 starts at an intersection of Main Street and SR-23 (Center Street) in Wellsville. Heading generally eastward, the highway terminates at the Hardware Ranch Wildlife Management Area. SR-101 was first designated in 1931 as a loop off SR-1 from Logan, south to Hyrum, and west to Wellsville. (Full article...)

Image 2Route 182 is a 0.96-mile (1.54 km) state highway in Hackettstown, New Jersey, United States. The highway serves as a connector of Route 57 to U.S. Route 46 (US 46). The southern end of Route 182 is at a three-way intersection, where Route 57 heads westbound towards Phillipsburg. Also present at this intersection is County Route 517 (CR 517), which is signed as Route 24, but not maintained by the state. CR 517 runs concurrent with Route 182 to its north end at US 46, and turns west with US 46 before splitting in downtown Hackettstown.
Route 182 was first an alignment of pre-1927 Route 12, but was not maintained by the state. In 1927, there was a renumbering, and it became part of Route S-24, which was a spur of Route 24. Route 24 at the time went along the alignment of Route 57, but when the second renumbering occurred in 1953, there was yet another change. In 1953, Route 24 was realigned onto most of Route S24, except for a short part which was designated Route 57. The highway went through a final change on October 9, 1969. On that day, there was a small renumbering of Hackettstown, with Route 24 being truncated to the three-way intersection, and Route 57 reassigned onto the rest of Route 24. The former alignment of Route 57 was reassigned as Route 182. (Full article...) -
Image 3State Route 149 (SR 149) is a short state highway in the U.S. state of California that helps to connect Oroville and Chico through rural Butte County. Connecting State Route 70 at Wicks Corner with State Route 99 east of Durham, it forms part of the primary north–south highway through the eastern Sacramento Valley, a Focus Route of the Interregional Road System.
SR 149 was formerly part of the Oroville-Chico Highway; the majority of the latter was merged into other routes. In the mid-1970s, the highway was reallocated onto a newer two-lane alignment. A project to widen the two-lane road to a four-lane expressway was completed in late 2008, removing the bottleneck from the Oroville-Chico highway. (Full article...) -
Image 4North Carolina Highway 98 (NC 98) is a primary state highway in the U.S. state of North Carolina and a semi-urban traffic artery connecting Durham, Wake Forest, and Bunn as well as many small to medium-sized towns in the north portion of The Triangle region of North Carolina. Running from downtown Durham, the route leaves the city to the east, running into a rural area near Falls Lake. As the road approaches Wake Forest, it widens to a four-lane divided highway and runs along the southern side of the city. Once leaving Wake Forest NC 98 becomes a two lane road again, running through rural areas east of Bunn. After a short concurrency with NC 39, NC 98 continues southeast to reach its eastern terminus at US 64 Alternate and NC 231 west of Spring Hope.
NC 98 first appeared in 1930 as a state route connecting NC 91 and NC 102 in the coastal region of North Carolina. That routing was abolished in 1931 in favor of an extended NC 58. The current routing of NC 98 was established in 1934 with the road's western terminus at NC 91 (present-day Jones Dairy Road) to US 64 west of Spring Hope. In 1941, NC 98 was moved to a new section of road running from Zebulon Road to US 1 in Youngsville, which would later become part of NC 96. In 1952, NC 98 was again relocated along NC 264 through Wake Forest to Durham, and NC 96 took over its abandoned section. In 2003, a bypass was completed around Wake Forest leading to the rerouting of mainline NC 98 to the bypass and the establishment of a business route through the town center. (Full article...) -
Image 5U.S. Highway 6 (US 6) is an east–west United States Numbered Highway which runs 322 miles (518 km) across the U.S. state of Iowa. The route is signed in places as the Grand Army of the Republic Highway. Like all state highways in Iowa, it is maintained by the Iowa Department of Transportation (Iowa DOT). The route begins at the Missouri River crossing at Council Bluffs. From there, it travels east through Oakland and Atlantic. North of Atlantic, the highway overlaps Interstate 80 (I-80) until De Soto. Between De Soto and Adel, the highway overlaps US 169 before splitting off to the east toward Des Moines. Through the Des Moines area, the highway runs about one mile (1.6 km) north or south of the I-35/I-80 corridor.
At Altoona, the route again overlaps I-80 until Newton, where it splits away from I-80. The highway passes near or through the cities of Kellogg, Grinnell, Victor, Marengo, the Amana Colonies, and Tiffin before entering the Iowa City metropolitan area. Through Coralville and Iowa City, US 6 has no direct access to I-80, I-380, or US 218; other routes like Iowa Highway 1 (Iowa 1) and Iowa 965 provide direct access. From Iowa City, the highway heads to the east-southeast through West Liberty and Atalissa. Near Wilton, the route heads north to I-80 where it again overlaps to Davenport. At Davenport, US 6 then follows I-280 and US 61 before entering the city. On the eastern side of Davenport, it joins I-74 and enters Bettendorf before leaving Iowa for Illinois. (Full article...) -
Image 6Mississippi Highway 572 (MS 572) is a former state highway in southwestern Mississippi. The route's western terminus was in Centreville of Wilkinson county. MS 572 traveled east and intersected MS 24 and MS 33, just east of the town. It ended at MS 569 south of Beechwood. MS 572 was designated in 1957, from MS 24 and MS 33 to MS 569. The route was extended west to Centreville, and was removed from the state highway system in 1967. (Full article...)

Image 7K-149 is a 6.098-mile-long (9.814 km) north–south state highway in the U.S. state of Kansas. Entirely within rural Morris County, K-149's southern terminus is at U.S. Route 56 (US-56) east of Herington and the northern terminus is at K-4 south of White City. The highway passes through grasslands characteristic of the Great Plains and is a two-lane road for its entire length.
K-149 was first designated as a state highway by the State Highway Commission of Kansas, now known as the Kansas Department of Transportation, on February 13, 1957. The highway's alignment has not changed since it was created. (Full article...) -
Image 8New York State Route 268 (NY 268) is a state highway located in southwestern Delaware County, New York, in the United States. It runs from NY 97 in Hancock north over 10 miles (16 km) to a bridge over Cannonsville Reservoir near the former site of the hamlet of Apex in Tompkins. There, it ends at a junction with NY 10. NY 268 meets the Quickway (NY 17) (Future Interstate 86) east of the Hancock village limits.
From Hancock to the NY 17 interchange, NY 268 follows the pre-Quickway routing of NY 17. Between NY 17 and NY 10, the route follows the former alignment of New York State Route 236, a connector between then-NY 17 and NY 10 that existed during the 1930s. In the floods of 2006 some of the areas along this rural highway suffered serious landslides, leading to a temporary closure of the road. (Full article...) -
Image 9Route 3 is a state highway in the northeastern part of New Jersey. The route runs 10.84 miles (17.45 km) from U.S. Route 46 (US 46) in Clifton, Passaic County, to US 1/9 in North Bergen, Hudson County. The route intersects many major roads, including US 46, which takes travelers to Interstate 80 (I-80) west for commuting out of the city-area, the Garden State Parkway and Route 21 in Clifton, Route 17 and the Western Spur of the New Jersey Turnpike (I-95) in East Rutherford, the Eastern Spur of the New Jersey Turnpike (also I-95) in Secaucus, and Route 495 in North Bergen, for traffic going to the Lincoln Tunnel into New York City. Route 3 serves as the main artery to the Lincoln Tunnel from I-80, in conjunction with a portion of US 46 and Route 495. Portions of the route are not up to freeway standards; with driveways serving businesses and bus stops. Despite this, many construction projects have been underway over the years to alleviate this issue. Route 3 also provided access to Hoffmann La Roche's former American headquarters in Nutley, the Meadowlands Sports Complex and American Dream in East Rutherford. The road inspired a story in The New Yorker in 2004 by Ian Frazier due to its views of the Manhattan skyline. Route 3 was originally the Lincoln Tunnel Approach and ended at the state line in the Hudson River, though it was scaled back following the construction of I-495; which is now Route 495 due to also not meeting interstate highway standards.
Route 3 was originally established in 1927 to run from the New York state line on the west shore of Greenwood Lake to Secaucus. In 1929, the western terminus was cut back to Paterson when the alignment west of there was planned to become part of Route S4B. Route 3 originally followed present-day Route 20 through Paterson and ran along local streets to East Rutherford, where it followed present-day Route 120 and Paterson Plank Road to Secaucus. It was extended east to the Lincoln Tunnel in 1939. The section of Route 3 between US 46 in Clifton and East Rutherford was completed in the 1940s as Route S3 as well as the Secaucus Bypass, which was designated a bypass of Route 3. Route 3 was moved to the Route S3 freeway and the Secaucus Bypass in 1953 and was truncated to US 1/9 in North Bergen in 1959 when the Lincoln Tunnel approach was designated as I-495. The Route 3 freeway has seen many improvements over the years, such as widening and interchange reconstructions. It underwent a major reconstruction, completed in 2016, to modern highway standards with bridge replacements, including a new Passaic River bridge between Clifton and Route 17 in Rutherford.

Image 10Maryland Route 16 (MD 16) is a state highway in the U.S. state of Maryland. The state highway runs 51.06 miles (82.17 km) from Taylors Island east to the Delaware state line in Hickman, where the highway continues as Delaware Route 16 (DE 16). MD 16 connects Cambridge with several communities in northern Dorchester County and southwestern Caroline County, including East New Market and Preston. The state highway runs concurrently with U.S. Route 50 (US 50) near Cambridge, MD 331 between East New Market and Preston, and both MD 404 and MD 313 near Andersontown. MD 16 was constructed between Church Creek and Preston as one of the original state roads in the early and mid-1910s. The highway was extended in both directions in the late 1910s: north to what was to be designated MD 313 near Denton and west to Taylors Island. MD 16 was extended through Andersontown to the Delaware state line in the early 1930s. MD 16's bypass of Cambridge was constructed in the mid-1960s. (Full article...)

Image 12Maryland Route 331 (MD 331) is a 28.74-mile (46.25 km) state highway on the Eastern Shore of Maryland in the United States. Signed north-south, the route runs from Vienna in Dorchester County northwest to Easton in Talbot County, intersecting U.S. Route 50 (US 50) at both ends. MD 331 is a two-lane undivided road most of its length that passes mostly through agricultural areas. The road also passes through the communities of Hurlock and Preston along the way. It encounters several routes during its journey, including MD 14 near Rhodesdale and MD 16 in the Preston area, both of which the route forms concurrencies with. In addition, the route also intersects with MD 392 and MD 307 in Hurlock and with MD 318 near Preston.
Most of present-day MD 331 was designated as part of US 213 in 1926 when the U.S. Highway System was established. By 1940, US 213 was moved to a new alignment that crossed the Choptank River at Cambridge on a bridge built in 1935 and MD 331 was designated to run from Vienna to Easton. Both ends of MD 331 have been shortened since, with the southernmost portion of MD 331 curtailed following the completion of the US 50 bypass of Vienna by the 1990s and the northern terminus of the route cut back to US 50 in 2004 when the state-maintained portion of Dover Road to Dover Street in Easton was turned over to the city.
