This unassuming freeway serves San Antonio's Eastside neighborhoods as well as industrial areas south of downtown and near Loop 410.  Residential areas line most of the route between I-37 and Loop 410; commercial and industrial uses front the corridor outside Loop 410 and between I-35 and I-37.  The corridor provides access to the AT&T Center and Freeman Coliseum, the San Antonio Missions Trail National Park, and the suburban city of Kirby.  New residential areas are sprouting-up between I-10 and FM 78 outside of Loop 410, especially along Foster Rd.  While the I-10 corridor east of Foster Rd. is mostly undeveloped, heavy residential and commercial development exists just a few miles north of I-10 along FM 78 and extending beyond Loop 1604.  Therefore, this route has become a favorite commuter route for motorists in the FM 78 corridor wanting to avoid the heavy traffic on I-35.

Future plans

TxDOT has long-range plans to widen I-10 to six lanes from Loop 410 to Loop 1604 and for major interchange improvements at both loops.  A fully-directional "stack" interchange was proposed at Loop 1604 as part of the Loop 1604 managed lanes project.  TxDOT is currently studying the feasibility of toll lanes from Loop 410 to Seguin.  These local plans dovetail on plans to widen I-10 to six lanes between San Antonio and Houston.

A project to add a WB entrance from and EB exit ramp to Roosevelt Ave is expected to start in 2017.


Authorized on October 1, 1959.  Named for Josť Lopez, a Medal of Honor recipient.  Was originally called the "East Expressway."

The section from Commerce eastward was completed by 1964.  West from WW White, the route was originally proposed to head northwest and meet I-35 near N. New Braunfels Ave.  By 1964, however, the present alignment was proposed and was completed by 1968.

TransGuide coverage was added to the section west of Roland Ave. in 1995.  Modifications to the section from Loop 410 to Foster Rd. were completed in 2009 and additional improvements at the Loop 410 interchange were made in 2010.

In September 2011, the Texas Transportation Commission approved extending the SH 130 designation along I-10 from the terminus of the SH 130 toll road east of Seguin to Loop 410, then south along Loop 410 to I-35 South.  Signage was installed in 2013.
