TxDOT has begun improvements to SH 151 between Loop 1604 and I-410 in Bexar County. The SH 151 project is designed to increase mobility, enhance safety, and reduce congestion along the corridor. Improvements include:

Increase traveling lanes to six lanes
Add inside shoulders and concrete median barrier
Improve entrance and exit ramps, intersections, and frontage roads
Add turnarounds for Military Drive W, Westover Hill Blvd, and Wisemen Blvd.
Direct connector allowing easy access to westbound 1604 northbound
This corridor has experienced an influx of growth over the last decade. This growth has led to the need for expanding and updating existing infrastructure. Road improvements are needed to enhance safety and mobility, including addressing the increase in traffic along this corridor.

Construction started in May 2023 and is estimated to be completed in December 2026.
