Interstate 2 comprises a well traveled freeway across the Rio Grande Valley in South Texas. Overlaying U.S. 83 for 46.8 miles, IH 2 runs east from Palmview through the cities of Mission, McAllen, Pharr, San Juan and Weslaco among others. The designation concludes at IH 69E/U.S. 77 in Harlingen, which angles southeast to Brownsville and the Veterans Bridge to Matamoras, Mexico. Designated as a branch of the IH 69 corridor, IH 2 improves mobility and improves freight traffic to points north with the connections with IH 69C/U.S. 281 north and the continuation of U.S. 83 to Laredo.
The west end of IH 2 is located at the grade separated interchange with Showers Road, west of Palmview. U.S. 83 extends from there along a five lane, at-grade boulevard through Penitas and La Joya. Construction along the north side of the two cities through January 2021 constructs the US 83 Relief Route, a new four lane, controlled access highway. Costing $57.16 million, the project (id: 003902040) constructs 6.7 miles of new roadway for U.S. 83 and future IH 2, from a point one mile east of FM 886, to the freeway end west of Showers Road.
