San Antonio Sets Plans for $500 Million US Highway 90 Expansion
San Antonio, Texas – The Texas Department of Transportation (TxDOT) has initiated a significant $500 million expansion project on US Highway 90, aiming to alleviate congestion and enhance mobility in the rapidly developing areas west of San Antonio. The project commenced in late 2025 and is expected to span several years, with completion anticipated in 2029.
Project Overview
The expansion focuses on widening US Highway 90 from a four-lane divided highway to a six-lane expressway between Loop 410 and Loop 1604. Key components of the project include:
- Phase One: Expansion of US Highway 90 from Loop 410 to Loop 1604, increasing capacity from four to six lanes. This phase also involves the construction of a flyover ramp connecting westbound US 90 to northbound Loop 1604. Estimated cost: $161 million. Completion expected in 2029.
- Phase Two: Extension of the six-lane expansion from Loop 1604 to State Highway 211. Estimated cost: $339 million. Completion expected in 2032. Funding for this phase is currently partial and subject to change.
Rationale and Impact
Traffic on US Highway 90 is projected to more than double over the next 20 years, increasing from 70,000 to 150,000 vehicles per day. The expansion aims to reduce future travel times by up to 90%, significantly improving connectivity and reducing congestion in the region. The project is strategically located near major residential and commercial developments in West Bexar County and East Medina County, addressing the growing transportation needs of these expanding communities.
