U.S. Highway 77 Alternate is a north-south auxiliary route of U.S. Highway 77, located entirely within the state of Texas. The route was commissioned in 1953, when US 77 was rerouted in southeast Texas.
Route description
US 77 Alternate begins at an intersection with US 77 in Refugio; US 183 also begins at this point, and runs concurrently with US 77 Alternate for approximately. While US 77 runs to the northeast towards Victoria, US 183/77 Alt. travel more to the north, through unincorporated Refugio County and into Goliad County. The routes intersectSH 239 south of Goliad, and run concurrently until they reach downtown Goliad and US 59 ; US 183/77 Alt. continue to the north, while westbound SH 239 turns onto southbound US 59. North of Goliad, past a junction with SH 119, the US routes begin to travel slightly toward the northeast. The next major city is Cuero in DeWitt County; in a wrong-way concurrency, southbound US 87 merges on to northbound US 183/77 Alt., and the three US routes stay merged until US 87 separates in downtown Cuero. North of Cuero, US 183 finally separates from US 77 Alt.; US 183 turns to the northwest, while US 77 Alt. turns sharply to the northeast, toward Lavaca County and Yoakum. West of Hallettsville, US 77 Alt. merges onto Alt. US 90, and the two routes stay merged until downtown Hallettsville, where the US 77 Alt. ends at another intersection with US 77.
History
The original routing of US 77 was to the southwest from Hallettsville, via Yoakum and Cuero, and then to the southeast to Victoria concurrent with US 87. In 1953, US 77 was transferred to the more direct north–south route to the east, replacingSH 295 between Hallettsville and Victoria; the original route from Hallettsville to Cuero was designated US 77 Alternate. In order to have it connect with US 77 at both ends, US 77 Alternate was designated to run concurrently with US 183 from Cuero to its southern terminus in Refugio.

Auxiliary route
US 77 Alternate has one business route in Yoakum. Officially designated by TxDOT as Business US 77-Q, it is signed with two auxiliary banners as Business Alternate US 77. The route was originally established as Loop 51 in 1939, and was redesignated in 1991. The route begins at US 77 Alternate south of Yoakum, then travels northwest into the city along Huck Street. It then turns north along Irvine Street, and has a brief concurrency with SH 111. It then turns northwest along Gonzales Street to an intersection with mainline US 77 Alternate.
