and notes


This unassuming freeway serves San Antonio's East Side neighborhoods as well as industrial areas south of downtown and around Loop 410. Residential areas line most of the route between I‑37 and E Houston St., while commercial and industrial uses front the corridor east of there and also between I‑35 and I‑37.

While the I‑10 frontage east of Foster Rd. is still mostly lightly developed, heavy residential and commercial development exists just north of I‑10 in the FM 78 corridor, and that development is now spreading southward to I‑10 all the way out to FM 1518, and, in the area around Loop 1604, now has even crossed over to the southern side of I‑10. As a result, commuter traffic is growing in this corridor. New industrial development is also occurring within and south of the I‑10 corridor in the Foster Rd. area, which has increased truck traffic in the corridor.

The corridor provides access to the Frost Bank Center and Freeman Coliseum, the San Antonio Missions Trail National Park, and the suburban cities of Kirby and Converse.

Heavy between I‑35 and Roland Ave. Moderate east of Roland Ave.

Recurring congestion occurs in the mornings and evenings in both directions between I‑35 and I‑37, and westbound approaching I‑37. Previous congestion in the Ackerman Rd. area has been relieved by the recent freeway expansion there.

Future plans

TxDOT has plans to upgrade both the Loop 410 and Loop 1604 interchanges. The first phase of a fully-directional, five-level "stack" interchange at Loop 410 is currently under construction. A future phase(s) will construct the remainder of the interchange.

A five-level "stack" interchange was proposed at Loop 1604 as part of an earlier Loop 1604 project, but it is now expected to be done as a standalone project.

A project to widen I‑10 through Seguin is started construction in early 2024. TxDOT plans to eventually widen all of I‑10 between San Antonio and Houston to six lanes.


US 90 and its predecessor SH 3 heading east to Seguin originally followed today's FM 78. A new alignment for US 90 that followed today's I‑10 east of Commerce St. was built in 1932 as part of the Arneson Plan to improve state highways in Bexar County. Most of that original alignment is where the westbound frontage road is today.

This freeway was originally called the "East Expressway" and was also known for a short time as the "Highland Park Expressway." It was renamed in 1994 for José Lopez, a Medal of Honor recipient. The designation as I‑10 was authorized on October 1, 1959.

The routing of the freeway between Loop 410 and downtown was subject to several revisions and some controversy before today's alignment was finalized in 1959. Planning for this route was done in conjunction with the planning for I‑37.
