I-10 San Antonio Area Freeway System
Interstate 10 East (Josť Lopez Freeway)

This page last updated September 10, 2023

I-10 East highlight map This page covers Interstate 10 south and east of downtown San Antonio from I-35 to Pfeil Rd. Two miles of I-10 is concurrent (multiplexed) with I-35 north of the western end of this segment; see the I-35 South page for details on that segment. Interstate 10 then continues northwest of downtown; see the I-10 West page for more info.

Length: 11 miles

Special features
& notes


This unassuming freeway serves San Antonio's East Side neighborhoods as well as industrial areas south of downtown and near 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 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 cities of Kirby and Converse. While the I-10 corridor itself east of Foster Rd. is still mostly lightly developed, heavy residential and commercial development exists just a few miles north of I-10 along FM 78, and that development is now creeping southward all the way out to FM 1518. 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. 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.

I-10 traffic map
Traffic volume legend

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.

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 expected to start construction in 2021. A five-level "stack" interchange was proposed at Loop 1604 as part of the Loop 1604 managed lanes project, but it will now be done as a standalone toll-free project. TxDOT plans to eventually widen all I-10 between San Antonio and Houston to six lanes.


US 90 and its predecessor SH 3 headed 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 Josť 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.

  • 1945: The earliest expressway plans would have routed this freeway from the WW White Rd. area northwest to join I-35 near AT&T Center Parkway.
  • 1952: An new proposal for this freeway would have used today's I-10 from Loop 410 to Salado Creek. From there, the route would have followed the Aransas Ave. corridor to near New Braunfels Ave. where it would have turned west and followed the Indiana St. corridor. After crossing today's I-37, it would have turned northwest and crossed Presa St. and St. Mary's St. at Sadie St. Continuing northwest, it would have crossed Alamo St., the King William District, and the San Antonio River between Sheridan St. and Beauregard St. It then would have continued along Arsenal St. and El Paso St. to an interchange with I-35.
  • 1956: The proposed alignment was shifted further south and included today's route between I-35 and I-37. From there, it would have continued east along the Bailey Ave. corridor to Clark Ave. before turning northeast to meet Houston St. just east of Commerce St. This route generated significant controversy.
  • 1959: The alignment for the route inside Loop 410 was finally settled. Meanwhile, the freeway segment from just inside Loop 410 to just west of FM 1516 was completed.
  • 1962: The freeway from FM 1516 to the county line was completed.
  • 1963: The first Interstate rest area in Texas opens on I-10 just west of FM 1518. (It was removed sometime around 2006.)
  • 1964: The section from Commerce St. to Loop 410 was completed as was the Loop 410 interchange.
  • 1967: The segment between I-35 and I-37 opened.
  • 1968: The section from Commerce St. to I-37 opened.
  • 1995: TransGuide coverage was added to the section west of Roland Ave. as part of the original TransGuide project.
  • 2009: Various operational improvements were made to the section between Loop 410 and Foster Rd.
  • 2010: Operational improvements were made at the Loop 410 interchange.
  • 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.
  • 2021: The section from Loop 410 to Loop 1604 was widened to six lanes.
