U.S. Route 380 (US 380) is an east–westUnited States highway. The highway's eastern terminus is inGreenville, Texas at an intersection withInterstate 30, of which the easternmost 3–4 miles are concurrent withUS 69 in a loop around the west and south sides of Greenville. Its western terminus is atSan Antonio, New Mexico, south ofSocorro at an intersection withInterstate 25. It intersected with its parent,U.S. Route 80, atCisco until 1971, when it was rerouted along the formerSH 24 from that highway's western terminus near Old Glory to Greenville. FormerU.S. Route 380 from Cisco to near Old Glory became an extension ofSH 6. The highway no longer connects to any x80 route. US 380 passes through some of the far northern suburbs of theDallas/Fort Worth Metroplex, including (from west to east)Denton,Frisco,McKinney andPrinceton. The portion in Texas from theNew Mexico state line toJayton wasSH 84 before 1939. Its spur,SH 84A, went from Jayton toAspermont, until 1930, when it becameSH 161.
US Route 380 begins at an intersection withInterstate 25 just west ofSan Antonio, New Mexico, and travels through town, meeting the old route ofUS 85, nowNew Mexico State Road 1. It then travels generally east, and marks the northern edge of theWhite Sands Missile Range. The road then turns southeast, crossing theCarrizozo Malpais before reachingCarrizozo, meetingU.S. Route 54. The route continues southeast, climbing theSacramento Mountains, and going through the town ofCapitan and briefly travelling through theLincoln National Forest, before reachingU.S. Route 70 atHondo and becoming concurrent with US 70.
These routes continue eastward, next reachingRoswell, New Mexico. US 380 splits with US 70 in Roswell, then crossingU.S. Route 285 in Roswell before continuing east across oil-producing areas of theLlano Estacado of east New Mexico and the TexasSouth Plains.
US 380 enters Texas at a crossing with Farm to Market Road 769, travelling generally due east before meeting up with US Route 82 inPlains. They continue east passing the former locations of Tokio and Gomez before reachingBrownfield. In Brownfield, it meets US Routes 62 and 385, and all 4 routes coincide for 3 blocks through the center of town before US 380 splits to the east.
The route continues due east through Texas South Plains farmland, passing throughTahoka, before falling off the Llano Estacado and reachingPost. The highway then meanders east through ruralGarza andKent Counties before reaching the ghost town ofClairemont. The route then travels east, where it meetsTexas State Highway 70, which both then turn northeast until reachingJayton, where US 380 takes a sharp turn back to the southeast. The road then travels through several thousand acres of private ranchland in Kent andStonewall Counties before reachingSwenson.
The route continues to the southeast, reaching an intersection with US 83, where both continue southeast into the town ofAspermont. The route continues to the east and northeast through the communities ofOld Glory,Rule,Haskell,Throckmorton, andNewcastle, before crossing Lake Graham and reaching the city ofGraham.
US 380 continues to the east and northeast throughBryson before reaching an intersection with US Route 281 andTexas State Highway 114 inJacksboro. US 281 departs southward out of town, while US 380 and TX 114 depart east south of Jacksboro, crossingLake Bridgeport before reaching the city ofBridgeport. US 380 then travels due east toward the city ofDecatur.
US 380 exits to the east and reaches an intersection withInterstate 35 on the west end ofDenton where it is known as University Drive. US 380 continues through the city of Denton, intersecting US Route 77 and US 377 nearTexas Woman's University, before continuing east with US 377. The routes cross the very northern edge ofLake Lewisville before US 377 departs off to the north. US 380 continues east through the town ofCross Roads and the city ofLittle Elm. Then US380 meets the northern terminus of theDallas North Tollway inFrisco, before reachingMcKinney, where it is also known as University Drive. The route then continues east, passing throughPrinceton before crossing the northern fringe ofLake Lavon, and reachingFarmersville, where it is signed as theAudie Murphy Parkway. The route again continues east, passing just south ofFloyd, before reaching an intersection with US Route 69 on the far western edge ofGreenville. Both of those routes then follow a loop around the south end of Greenville, before reaching the routes eastern terminus at an intersection with Interstate 30 and US Route 67.
The route has twospecial routes, both business routes in Texas.
This is the former route of US 380 through the city of Decatur. The route was bypassed in 1987, with the old route being renamed Texas State Highway Loop 569. The route was re-designated as the business route in 1991.
This is the former route of US 380 through the town of Floyd. The route was bypassed in 1968, when the route was still known asTexas State Highway 24, with the old routing being designated as Texas State Highway Loop 462. The route was re-designated as the business route in 1991.
 U.S. Highway 566 | |

| Location | Ruidoso, New Mexico–Socorro, New Mexico |
| Existed | 1926–1931[1] |
When US 380 was commissioned in 1931, it took over the entire former route ofU.S. Route 566,[1] an original 1926 route. The entire route of US 566 was within the state ofNew Mexico, from an intersection with (modern dayNew Mexico State Road 48) and (modern-dayUS 70) east ofRuidoso toUS 85 (originally planned asUS 466) inSocorro, New Mexico. US 566 never intersected with its nominal parent,U.S. Route 66 although it temporarily connected to that parent indirectly viaU.S. Route 366.
The section of highway from the New Mexico state line toJayton was previously SH 84. A spur route, SH 84A, went from Jayton to Aspermont, being changed toTexas State Highway 161 in 1930.
US 380 east of Denton, and west of McKinney,[2] has had numerous fatal vehicle accidents, per public statements by law enforcement and fire department officials. This is believed to be attributed by the lack of a center median, high traffic volume, and excessive speeds.[3]
