Interstate 2 in Texas is an Interstate Highway designation in the Rio Grande Valley of southern Texas. The route follows a limited‑access corridor that parallels U.S. Route 83 between Hidalgo and Brownsville, serving population centers such as McAllen and Weslaco. The corridor provides regional connectivity among border crossings, McAllen–Miller International Airport, and the Port of Brownsville.
Interstate 2 begins near Hidalgo at an intersection with U.S. 83 and proceeds eastward as a controlled‑access highway through Pharr, McAllen, Mission, and Weslaco. The highway parallels Rio Grande tributaries and crosses corridors used by Union Pacific Railroad and South Texas (UP), intersecting state highways such as SH 107, SH 365, and SH 495. As it continues, the route passes near University of Texas Rio Grande Valley, provides access to La Plaza Mall and La Joya ISD facilities, and connects to FM 1016 and FM 88. The eastern terminus meets I‑69E and U.S. 77 in Brownsville, close to the Brownsville–South Padre Island International Airport and the Queen Isabella Causeway to South Padre Island.
The corridor that became Interstate 2 traces back to improvements on U.S. 83 and state expansions during the late 20th century under programs influenced by the Federal Aid Highway Act of 1956. Growth in Hidalgo County and Cameron County prompted upgrades associated with regional initiatives involving Texas Department of Transportation, U.S. Department of Transportation, and local governments including McAllen and Brownsville. Major projects tied to the designation included widenings funded through state bonds and federal grants coordinated with entities such as American Association of State Highway and Transportation Officials and advocacy by representatives from the United States House of Representatives delegations for the 15th District and the 34th District. The Interstate 2 number was officially applied following approval from the American Association of State Highway and Transportation Officials and concurrence by the Federal Highway Administration, formalizing the corridor as part of the Interstate Highway System.
Proposed projects for the corridor include further interchange reconstructions near McAllen–Miller International Airport, managed lanes studies near Pharr and Mission, and safety enhancements coordinated with National Highway Traffic Safety Administration recommendations. Regional plans by the Rio Grande Valley MPO contemplate extension concepts tying the corridor more directly into I‑69E and potential connector routes toward Harlingen and Port of Brownsville infrastructure upgrades. Environmental reviews have involved inputs from U.S. Fish and Wildlife Service and state historic preservation authorities concerning impacts to riparian zones along the Rio Grande and cultural resources associated with Lower Rio Grande Valley communities.
The exit sequence includes interchanges serving U.S. 281 connections, major arterial cross streets such as International Boulevard, Griffin Parkway, and access to I‑69E at the eastern terminus in Brownsville. Exits provide direct access to commercial centers including La Plaza Mall, civic institutions like McAllen Convention Center, and healthcare facilities such as McAllen Medical Center. The list reflects mileposts increasing from west to east and conforms to exit numbering practices used across Texas Department of Transportation controlled highways.
Traffic volumes on the corridor are influenced by cross‑border commerce at nearby crossings including the Hidalgo–Reynosa International Bridge, Pharr–Reynosa International Bridge, and Brownsville & Matamoros International Bridge. The route handles commuter flows serving University of Texas Rio Grande Valley, seasonal tourism to South Padre Island, and freight movements to the Port of Brownsville. Peak hour counts reflect congestion nodes near McAllen and Weslaco, leading to corridor management measures coordinated with Texas Department of Public Safety and local transit providers such as Metro McAllen.
Major junctions along the route include connections with U.S. 83 at the western end, state highways such as SH 107 and SH 365, principal urban arterials in McAllen and Mission, and the eastern terminus at I‑69E/U.S. 77 in Brownsville. These intersections interface with regional freight corridors used by Union Pacific Railroad and port access routes to the Port of Brownsville.
