Interstate 37 (I-37) is a 143-mile (230 km) Interstate Highway located within the southern portion of the US state of Texas. The highway was first designated in 1959 as a route between Corpus Christi and San Antonio. Construction in the urban areas of Corpus Christi and San Antonio began in the 1960s, and the segments of the Interstate Highway in rural areas were completed by the 1980s. Prior to I-37, the route between Corpus Christi and San Antonio was served by a combination of State Highway 9 (SH 9) from Corpus Christi to Three Rivers and US Highway 281 (US 281) from Three Rivers to San Antonio. As a result of the construction of I-37, SH 9 was removed from the State Highway System.

For its entire length, I-69E runs concurrently with U.S. Highway 77 (US 77). The route currently exists in two segments: a 56.894-mile (91.562 km) segment from its southern terminus in Brownsville to the Willacy–Kenedy county line and a shorter 7.672-mile (12.347 km) segment south of Corpus Christi.

Interstate 169 (I-169) is an auxiliary route of I-69E in Texas that currently runs from I-69E in Brownsville southeast concurrently with State Highway 550 (SH 550), a toll road under construction that connects to the Port of Brownsville for 1.5 miles (2.4 km). When SH 550 is complete, it will be a limited-access toll route around the northern and eastern edges of Brownsville and signed as I-169, partly replacing and expanding Farm to Market Road 511 (FM 511). Its purpose is to provide a new entry point for truck traffic to the Port of Brownsville and forming a loop that allows traffic to bypass the northern sections of the urbanized extent of the Brownsville city limits. This may serve as a relief route for future traffic congestion and as a future business corridor.
