IH 37 (CSJ: 0073-08-183)

TxDOT District: San Antonio is executing a major roadway expansion along Interstate 37 in San Antonio, a project valued at $32,801,454. The work, identified in filings as IH 37 (Csj: 0073-08-183), involves new construction of intersection operational improvements and ramp revisions between IH 410 and SL 13 (SE Military Dr). This infrastructure project covers 63,606 sq ft of designated work area, placing its estimated cost at $516 per square foot.

Project Scope and Design

The scope of work focuses on enhancing traffic flow and connectivity at key junctions along the highway corridor. Kimley-Horn & Associates, Inc. serves as the design firm of record for this undertaking. The project is registered with TDLR under the accessibility specialist Frank Fonseca, ensuring compliance with state standards for public infrastructure. This specific filing represents a significant investment in Bexar County transportation, with TDLR status marked as Review Complete.

Construction is scheduled to start in June 2026 and is scheduled to finish in September 2028. This timeline reflects a planned build window of 823 days, which is longer than the median scheduled build window of 208 days for similar new construction filings in the county. The project utilizes public funds and is situated on public land, qualifying it as a Federally funded roadway project under state oversight.

Local Impact and Context

The project is located in the 78223 ZIP code area, where the U.S. Census Bureau estimates a population of about 57,298 residents. Median household income in this area is reported at $50,352, with a median owner-occupied home value of $156,700. The construction activity will occur in a region where housing is mostly owner-occupied, potentially affecting local traffic patterns during the two-year build period.

Third-party coverage, such as a post by myneighborhoodnews.com, described the IH 37 Operational Improvements Project as a $32.8M TxDOT initiative stretching from IH 410 to SL 13. This aligns with the official filing details regarding the route and estimated cost.
