Unsigned highway in the context of "Old Country Road"

U.S. Route 25E (US 25E) is the eastern branch of US 25 from Newport, Tennessee, where US 25 splits into US 25E and US 25W, to North Corbin, Kentucky, where the two highways rejoin. The highway, however, continues as US 25E for roughly two miles (3.2 km) until it joins Interstate 75 (I-75) in the Laurel County community of North Corbin at exit 29. The highway serves the Appalachia regions of Kentucky's Cumberland Plateau and the Ridge-and-Valley section of East Tennessee, including the urbanized areas of Corbin and Middlesboro in Kentucky and Morristown in Tennessee.

US 25E follows the original pathway of early U.S. pioneer Daniel Boone's Wilderness Road, which contributed to the increased settlement of Appalachia given its access through the rugged Cumberland Gap. By 1815, the route became the first state-funded road in Tennessee and, in 1923, unsigned State Route 32 (SR 32) in the Tennessee State Route System in its statewide entirety. It would be recognized as part of the Dixie Highway, one of the earliest federal auto trails, in 1915. The route was officially established as US 25E with the creation of the U.S. Numbered Highway System in 1926.

Central Expressway is a north–south highway in the Dallas-Fort Worth Metroplex in Texas (USA) and surrounding areas. The best-known section is the North Central Expressway, a name for a freeway section of U.S. Highway 75 between downtown Dallas and Van Alstyne, Texas. The southern terminus is south of the Woodall Rodgers Freeway at exit 284C of "hidden" Interstate 345 (signed as Interstate 45 southbound and US 75 northbound). From there, Central Expressway becomes the South Central Expressway, the northernmost portion of which was renamed César Chávez Boulevard on April 9, 2010.

US Highway 131 (US 131) is a north–south United States Numbered Highway, of which all but 0.64 of its 269.96 miles (1.03 of 434.46 km) are within the state of Michigan. The highway starts in rural Indiana south of the state line as a state road connection to the Indiana Toll Road. As the road crosses into Michigan it becomes a state trunkline highway that connects to the metropolitan areas of Kalamazoo and Grand Rapids before continuing north to its terminus at Petoskey. US 131 runs as a freeway from south of Portage through to Manton in the north. Part of this freeway runs concurrently with Interstate 296 (I-296) as an unsigned designation through Grand Rapids. US 131 forms an important corridor along the western side of the Lower Peninsula of Michigan, running through rural farm and forest lands as well as urban cityscapes. Various names have been applied to the roadway over the years. The oldest, the Mackinaw Trail, originated from an Indian trail in the area while other names honored politicians. An attempt to dedicate the highway to poet James Whitcomb Riley failed to gain official support in Michigan.

The first state highways along the US 131 corridor were designated as early as 1919. When the US Highway System was formed on November 11, 1926, US 131 was created along the route of M-13 in Michigan. Originally ending at Fife Lake on the north end, the highway was extended to Petoskey in the late 1930s. Further changes were made, starting in the 1950s, to convert segments of the road to a full freeway. The state started this conversion simultaneously at two locations: heading north from Three Rivers, and heading both north and south from a point in southern Kent County. A third segment was built south of Cadillac and over subsequent years Michigan filled the gaps in the freeway. Cadillac and Manton were bypassed in the early part of the 21st century, resulting in the current freeway configuration. Another large-scale construction project in 2000 rebuilt an unusual section of the freeway through Grand Rapids known as the S-Curve. Two bridges formerly used by US 131 have been labeled by the Michigan Department of Transportation (MDOT) as historic structures; one of them has been listed on the National Register of Historic Places (NRHP).

State Route 32 (SR 32) is a state highway in East Tennessee. For most of its route, it is an unsigned companion route concurrent with U.S. Route 25E (US 25E). The highway stretches 89 miles from the North Carolina state line to the Tennessee-Kentucky state line near the town of Cumberland Gap.

From the junction with US 25W-US 70 in Newport to the Kentucky-Tennessee state line at the Cumberland Gap, SR 32 is designated as the East Tennessee Crossing Byway, a National Scenic Byway. SR 32 is also designated as Appalachian Development Highway System (ADHS) Corridor S. The corridor follows SR 32 between I-81 in Morristown and State Route 63 (ADHS Corridor F) in Harrogate.

New York State Route 878 (NY 878) is an expressway on Long Island in New York state. The route exists in two sections, which both form the Nassau Expressway. NY 878's western terminus is the Belt Parkway and Conduit Avenue (NY 27) in Ozone Park, within southern Queens in New York City. Its southern terminus is at the Atlantic Beach Bridge in Lawrence, within southwestern Nassau County. NY 878 is discontinuous between Farmers Boulevard in Queens and the town of Inwood in Nassau County. The two sections are connected to each other by Rockaway Boulevard and Rockaway Turnpike.

NY 878 is maintained in part by the New York City Department of Transportation (NYCDOT); the New York State Department of Transportation (NYSDOT); and the government of Nassau County. The NYSDOT also maintains part of Rockaway Boulevard, which is designated as the reference route NY 909G. The 0.70 miles (1.13 km) of NY 878 between I-678 and the JFK Expressway is officially designated Interstate 878 (I-878), but not signed as such. This segment is instead signed as NY 878. The NYSDOT designated the eastbound lanes of the freeway as I-878 in January 1970, but the entire Nassau Expressway was publicly re-designated as NY 878 by 1991. The unsigned Interstate 878 is the shortest Interstate Highway in the United States.

The Garden State Parkway (GSP) is a controlled-access toll road that stretches the north–south length of eastern New Jersey from the state's southernmost tip near Cape May north to the New York state line at Montvale. Its name refers to New Jersey's nickname, the "Garden State". The parkway has an unsigned reference number of Route 444 by the New Jersey Department of Transportation (NJDOT). At its north end, the road becomes the Garden State Parkway Connector, a component of the New York State Thruway system that connects to the Thruway mainline in Ramapo, New York.

The Garden State Parkway is the longest highway in the state at approximately 172 miles (277 km), and, according to the International Bridge, Tunnel and Turnpike Association, was the busiest toll road in the United States in 2006. Most of the highway north of the Raritan River runs through heavily populated areas. Between the Raritan River and Toms River, the highway passes through lighter suburban development, while south of Toms River, the road mostly runs through unspoiled wilderness in the Pine Barrens and swampland, interspersed with small towns and Jersey Shore beach communities. The highway has a posted speed limit of 65 miles per hour (105 km/h) for most of its length and is primarily for passenger vehicle use; trucks weighing over 10,000 pounds (4,500 kg) are prohibited north of exit 105.

U.S. Route 19E (US 19E) is a divided highway of US 19 in the U.S. states of North Carolina and Tennessee. The United States Numbered Highway, which is complemented by US 19W to the west, travels 75.9 miles (122.1 km) from US 19 and US 19W at Cane River, North Carolina, north to US 11E, US 19, and US 19W in Bluff City, Tennessee. US 19E connects Asheville, North Carolina, and Bristol, Tennessee, with Burnsville, Spruce Pine, and Elk Park in North Carolina and Roan Mountain and Elizabethton in Tennessee. US 19E also has an unsigned concurrency with State Route 37 (SR 37) for its entire course in Tennessee.
