U.S. Route 80 or U.S. Highway 80 (US 80) is a major east–west United States Numbered Highway in the Southern United States, much of which was once part of the early auto trail known as the Dixie Overland Highway. As the "0" in the route number indicates, it was originally a cross-country route, from the Pacific Ocean to the Atlantic Ocean. Its original western terminus was at Historic US 101 in San Diego, California. However, the entire segment west of Dallas, Texas, has been decommissioned in favor of various Interstate Highways and state highways. Currently, the highway's western terminus is at an interchange with Interstate 30 (I-30) on the Dallas–Mesquite city line. Its eastern terminus is in Tybee Island, Georgia near the Atlantic Ocean. Between Jonesville, Texas and Kewanee, Mississippi, US 80 runs parallel to or concurrently with Interstate 20. It also currently runs through Dallas, Texas; Shreveport, Louisiana; Jackson, Mississippi; Montgomery, Alabama; Columbus, Georgia; Macon, Georgia; and Savannah, Georgia.
State Highway 121 is a state highway angling from southwest to northeast through north central Texas. It runs from Cleburne, Texas at US 67 to SH 78 in Bonham, Texas, just north of a junction with US 82.
Loop 12 is a state highway that runs mostly within the city limits of Dallas, Texas. The western segment of the loop is named after General Walton Walker, who served and died in South Korea. During the 1950s and 1960s, Loop 12 was the outer beltway in the Dallas area, having since been supplanted by Interstate 635 (I-635), which is itself being supplanted by the President George Bush Turnpike. Loop 12 is, however, the only state highway in Dallas that forms a complete loop.
State Highway 78 is a state highway that follows surface roads in a predominantly southwest-to-northeast direction in the Dallas area before traveling 90 miles (145 km) north-northeast to the Oklahoma State border.
Interstate 35E (I-35E), an Interstate Highway, is the eastern half of I-35, where it splits to serve the Dallas–Fort Worth metropolitan area. I-35 splits into two branch routes, I-35W and I-35E, at Hillsboro. I-35E travels north for 97 miles (156 km), maintaining I-35's sequence of exit numbers. It travels through Dallas before rejoining with I-35W to reform I-35 in Denton.
State Highway 180 is a highway that runs through Tarrant County and Dallas County in Texas (USA) between Interstate 35W in Fort Worth, running east to Loop 12 in Dallas. From Loop 12 in Dallas to Interstate 35W in Fort Worth, State Highway 180 follows the old routing of U.S. Route 80. Signage still shows the part from Loop 12 to Beckley Boulevard as SH-180 although it had been removed from the state system in 2014.
U.S. Route 77 (US 77) is a major highway that is part of the United States Numbered Highway System that runs from the Veterans International Bridge in Brownsville to Sioux City, Iowa. In Texas, the road runs south-north for 471.3 miles (758.5 km) from the International border with Mexico to the Oklahoma state line north of Gainesville. The highway is being upgraded to a freeway near Corpus Christi to connect to the freeway part of the highway in Raymondville as part of future I-69. A freeway in Robstown is already signed as part of I-69. From Waco to the Oklahoma state line, US 77 overlaps or runs parallel to I-35/I-35E.
Interstate business routes are roads connecting a central or commercial district of a city or town with an Interstate bypass. These roads typically follow along local streets often along a former U.S. Route or state highway that had been replaced by an Interstate. Interstate business route reassurance markers are signed as either loops or spurs using a green shield shaped sign and numbered like the shield of the parent Interstate highway.
Spur 482, known better as Storey Lane, is a short connector route located in the Dallas area. The route originates at the site of the former Texas Stadium and ends northwest of Love Field.
