Interstate 2

Interstate 2 (I-2) is a partially completed Interstate Highway running through the Lower Rio Grande Valley of South Texas. It begins at an interchange with Showers Road (SH 364) in Palmview and heads eastward before terminating at I-69E/US 77/US 83 in Harlingen. A US 83 bypass, separate from I-2, was constructed to interstate standards around Peñitas, La Joya, and Sullivan City and was completed in phases from 2023 to 2024. For its entire length, I-2 runs concurrently with US 83. I-2 also parallels Mexican Federal Highway 2 (Fed. 2), another major east–west route that traces the Mexico–US border along the Mexican side of the Rio Grande. It was signed as an Interstate in 2013. TxDOT studies have explored the possibility of extending I-2 along the US 83 corridor to a western terminus of Laredo. The potential extension is a part of broader planning for an expansion of the Interstate System into southern Texas that includes the three branches of I-69 throughout the Rio Grande Valley, as I-2 intersects with I-69E in Harlingen and I-69C in Pharr. If extended to Laredo, it would terminate at the future I-69W corridor as well. This complex of Interstate Highways does not currently connect to the rest of the system, with buildout of the Rio Grande Valley freeways providing connections to I-35 and I-37.
