Scope and Design

TxDOT District: San Antonio is the owner of record for Csj: 0521-04-285, which aims to improve traffic flow through direct connector improvements from US 281 to IH 410 Westbound. The scope includes ramp revisions, frontage road upgrades, and intersection improvements designed to handle the volume typical of this busy junction. Lina T. Ramey & Associates, Inc. is the registered design firm, bringing experience from several other TDLR-registered projects across the state, including work in Denton and Terrell.

Construction is scheduled to begin in July 2026, following the completion of plan review in March 2026. The project is scheduled to finish in January 2029, resulting in a build window of 918 days. This timeline is longer than the 208-day median build window for new construction projects in Bexar County, reflecting the complexity of modifying active interstate and U.S. highway infrastructure. The cost per square foot is $1,483, which is above the county median of $115 for new construction filings.

The project is located in ZIP code 78216, an area with a population of about 42,044 and a median household income of $55,488 according to U.S. Census estimates. Nearby businesses include H-E-B, Little Caesars Pizza, and the ECK Temple of South Texas. The area is characterized by a mix of residential and commercial activity, with housing that is mostly renter-occupied. The unemployment rate in Bexar County was 4.7 percent in July 2026, higher than a year earlier.

TDLR registration for Csj: 0521-04-285 was completed in March 2026, with the status marked as Review Complete. Frank Fonseca is the registered accessibility specialist for the project. The filing includes documentation of a virtual public meeting held on November 5, 2021, indicating early community engagement for this long-term improvement plan. The project represents a significant investment in the region’s transportation infrastructure, aiming to reduce congestion and improve safety for drivers and pedestrians alike.
