San Antonio Area Freeway System
PROJECT INFO: Loop 410 from Ingram to US 90

This page last updated May 20, 2023

ADVERTISEMENT

Project locationLocation
Loop 410/SH 151 interchange including Loop 410 from Ingram Rd. to US 90

Status
Phase 1: Completed in 2018
Phase 2: Completed in 2023

Timeline
Future projects to complete the remainder of the SH 151/Loop 410 interchange are currently unfunded and therefore have no timeline.

Description
Phase 1 of this $81.8 million project constructed the first two flyovers at the interchange at Loop 410 and SH 151, widened Loop 410 to eight lanes from Ingram to SH 151, and made various ramp improvements on Loop 410 and on SH 151.

Phase 2 built the eastbound SH 151 to southbound Loop 410 and northbound Loop 410 to westbound SH 151 flyovers. This project also widened Loop 410 to ten lanes from Ingram to SH 151 and to eight lanes from SH 151 to US 90.

How this project will help
The additional flyovers at the Loop 410/SH 151 interchange will improve operations and reduce congestion in the interchange and adjacent access roads. The additional lanes on Loop 410 should accommodate expected future traffic volumes.

FAQ

  • Why is construction starting again less than a year after the first phase was completed and before the work south of SH 151 is done?
    This is because TxDOT's funding was increased significantly a few years ago, so backlogged projects are getting funded much sooner than expected. Phase 2 of this project is one of those backlogged projects that has been expedited due to the new funding; it was originally expected there would be five or more years between phases.
