Interstate 2

I-2 Texas


The Interstate 2 designation applies to 46.8 miles of preexisting U.S. 83 freeway between a point west of Mission and the new Interstate 69E in the Lower Rio Grande Valley of Texas. The route serves McAllen, Pharr (Interstate 69C), Donna, Weslaco, Mercedes and Harlingen. Long range plans may extend I-2 northwest along U.S. 83 to Laredo.


An application by TXDOT to the American Association of State Highway and Transportation Officials (AASHTO) for the designation of Interstate 2 was approved at the May 5, 2013 Route Numbering Committee meeting. The new route was coupled with the designations of Interstate 69C (Central) and 69E (East), and signs for all three debuted at ceremonies held in both Pharr and Harlingen on July 15, 2013.1

Interstate 2 was sought to form an Interstate connector between the legs of I-69 by the Alliance for I-69 Texas and Lower Rio Grande Valley community leaders.2 Signing of the route and Interstates 69C and 69E was made possible by the Moving Ahead for Progress in the 21st Century (MAP-21) legislation passed in 2012.2

Exit numbers and mileposts were added to Interstate 2 through the Rio Grande Valley by January 2016. They reflect the distance from Laredo, the long range planned west end of IH 2.

U.S. 83 was rerouted between Mission and Harlingen between 1963 and 1966. This bypass was upgraded to a freeway in 1971-72.

The U.S. 77 freeway southeast from Harlingen to San Benito was constructed at the same time as the U.S. 83 freeway.
