The Texas Department of Transportation is planning to expand a two-mile segment of Potranco Road (FM 1957) to six lanes to address traffic growth on San Antonio's far West Side. The project, which impacts travel between Texas 211 and Country Road 381, includes added drainage and pedestrian paths.
Why it matters
Daily traffic volumes on this roadway have surged from 3,000 vehicles in 2006 to 13,653 in 2025, necessitating infrastructure upgrades to manage the increased congestion. This project aims to improve local transit logistics and safety for residents in the growing corridor straddling Bexar and Medina counties.
The plan upgrades a two-mile stretch between Texas 211 and Country Road 381 to six lanes, following a 355% increase in daily traffic over the last two decades. The department is soliciting public feedback during an open house on October 21, 2026, at the San Antonio Glasshouse.
The players
Texas Department of Transportation
The state agency responsible for maintaining and expanding highway infrastructure and managing long-term transportation planning across Texas.
The details
The proposed expansion transforms the current roadway by adding travel lanes, raised concrete medians, and dedicated infrastructure for cyclists and pedestrians. Drainage enhancements are also included to manage stormwater along the corridor. Residents can review specific plans and provide feedback directly to the agency representatives during the upcoming scheduled open house.
Timeline
2006: Daily traffic count was 3,000 vehicles.
2025: Daily traffic count reached 13,653 vehicles.
October 21, 2026: Open house for the project at the San Antonio Glasshouse.
2031: Construction is expected to begin.
The Home Front
This project reflects the ongoing regional effort to scale roadway capacity in response to the rapid population growth on San Antonio's far West Side. Such infrastructure upgrades often influence long-term property values and commute logistics for households residing near major county corridors.
If you live along the Potranco Road corridor between Texas 211 and Country Road 381, review the expansion maps at the upcoming open house to understand how new medians may affect your property access. Plan for potential long-term construction traffic once the project commences in 2031.
The takeaway
Large-scale infrastructure shifts often have multi-year planning cycles that provide homeowners ample time to prepare for local changes. Keep an eye on regional transportation updates to see how the finalized 2031 construction schedule might align with your future home improvement or moving plans.
What happens next
Public feedback is requested at the project open house on October 21, 2026.
