U.S. Highway 57 (US 57) is a 98-mile (158 km) north–south intrastateUnited States highway that follows a nearly east–west route in the southwestern part of the U.S. state ofTexas. The highway's northern (eastern) terminus is about 50 miles (80 km) south ofSan Antonio, Texas, betweenDevine andPearsall, at anintersection withInterstate 35 (I-35; oldU.S. Highway 81). Its southern (western) terminus is inEagle Pass, at theRio Grande (Río Bravo), where it continues intoPiedras Negras, Coahuila, asMexican Federal Highway 57.
US 57 begins at theEagle Pass – Piedras Negras International Bridge inEagle Pass. The highway travels eastward through Eagle Pass on Garrison Street. On the east side of town, it turns northeast briefly and intersects US 277 Business on Main Street before turning back to the east. Six blocks later, it reaches the intersection with the main branch ofUS 277 andFM 3443. US 57 continues east, now concurrent with southbound US 277. About 1 mile (1.6 km) further, the highways diverge, with US 57 veering to the northeast.[2] The highway travels through ranchland inMaverick County and travels through aUnited States Border Patrolinterior checkpoint before reachingLa Pryor, where it intersectsUS 83.[3] US 57 continues eastward throughBatesville and unincorporated areas ofZavala andFrio counties, intersecting several Farm to Market roads, before reaching its eastern terminus atInterstate 35 (I-35) southwest of the town ofMoore.[4]
This 98-mile (158 km) highway was originally designated in 1933 asTexas State Highway 76, which was previously designated in 1926 on a route from Nacogdoches to Joaquin which was replaced by SH 7 in 1933. From 1942 to 1964, its eastern half was reassigned toFarm to Market Road 394 (FM 394). In 1966, the state changed the highway's number to 57 to provide continuity withMexican Federal Highway 57, a similarly-numbered route across theMexican border.
In 1970, the highway was commissioned as a United States Highway,[5] and retained its "57" designation to create a single-numbered international corridor.[6] The highway is signed south–north, even though it travels much closer to an east-west direction. However, Mexican Federal Highway 57 travels south toMexico City, so the unusual directional signing prevents confusion.
In 2022, the Texas Department of Transportation (TxDOT) released a feasibility study on upgrading US 57 into an Interstate.[7] The study concluded that US 57 should be widened to a four-lane divided highway from Loop 480 near Eagle Pass to Interstate 35 near Moore that will serve as a progression to an Interstate in the future.[8] In June 2025, TxDOT contracted an engineering firm as a consultant for development and design, but formal approval for the project is subject to the availability of public funds for the project.[9]
