History

US 77 was designated in 1927 from Gainesville to Corpus Christi. In 1943, the highway was extended south of Corpus Christi to the international border at Brownsville; this extension also rerouted the section of highway between Sinton and Corpus Christi, as the previous route traveled through Gregory between the two towns. In 1953, US 77 was rerouted between Halletsville and Victoria over former SH 295. The section of highway through Victoria was rerouted in 1978 to remove a concurrency with US 59, but this cancelled the following year. In 1997, US 77 was extended so the highway's official designation ran to the Los Tomates International Bridge in Brownsville. In 2000, the city of Denton turned US 77 into a pair of one-ways streets from US 377 to FM 2164, with northbound traffic using Locust Street and southbound traffic using Elm Street. In 2003, the section of US 77 in Robstown between FM 892 and 9th Street was removed the state highway system as construction of a bypass around the town began. In August 2011, TxDOT received permission from the

South of Corpus Christi, US 77 is a freeway around most of Kingsville, with interchanges being constructed at US 77 Bus. and FM 1717 south of the town that would complete the freeway in Kingsville.

, though the Kingsville and Bishop freeways are currently not connected. A bypass of Driscoll is being constructed, with the northbound lanes open to traffic while the southbound lanes are expected to open in 2022. Between Corpus Christi and Victoria, US 77 is still mostly a divided highway that does not bypass most of the towns it travels through. As of June 2022, Sinton is the only town along this section of US 77 that the highway bypasses. Once completed, I-69E will end at I-69W (US 59) in Victoria, with those two Interstates forming I-69.
