San Antonio, Texas – As Texas navigates rapid growth, the Texas Department of Transportation (TxDOT) is launching significant infrastructure projects in 2026 designed to improve mobility and reduce congestion across the state. These initiatives represent an opportunity for local entrepreneurs and businesses by streamlining transport routes, fostering connectivity, and supporting the resilient spirit of Texas entrepreneurs. By focusing on innovative solutions and infrastructure investment, the state is creating an environment ripe for economic growth and opportunity.
The need for efficient transportation systems becomes more pressing amid Austin’s booming economy and surrounding regions.

Major Infrastructure Projects in 2026
Loop 1604 North Expansion
The Loop 1604 North Expansion is a pivotal project for San Antonio, targeting a widening of the highway from four to ten lanes between I-35 and Judson Road. This expansion aims to decrease travel times by up to 80 minutes upon completion, projected for 2028. With an updated funding total of $215.8 million for phase six, the project represents a substantial commitment to improving transportation infrastructure in the region.
I-35 Capital Express Projects
The I-35 Capital Express program entails three significant segments: North, Central, and South. Each segment focuses on reconstructing and expanding I-35 to enhance traffic flow and ensure safety. With various phases expected to kick off or gain momentum throughout 2026, this effort aligns with the needs of growing urban populations and crowded roads.
Interstate 10–Loop 1604 Interchange Reconstruction
In San Antonio, the I-10–Loop 1604 interchange—popularly known as the Fiesta Stack—is undergoing reconstruction as part of the Loop 1604 North Expansion Program. This five-level stack interchange aims to boost mobility and alleviate congestion along one of the city’s busiest northern corridors, with an anticipated completion date set for late 2026.
Grand Parkway Widening
TxDOT’s Grand Parkway Widening project involves extending highway capacity between I-10 West and U.S. 290. With environmental and design work projected to conclude in early 2026, construction is set to commence later that year. This project reflects a commitment to supporting the region’s rapid growth and ensuring sufficient infrastructure.
Statewide Transportation Investment Plan
In a further demonstration of commitment to transportation improvements, Governor Greg Abbott announced a sweeping 10-year transportation plan, aiming to invest over $146 billion. This includes $101.6 billion earmarked specifically for capital projects to boost safety, connectivity, and efficiency across Texas highways. Key initiatives in the Austin area consist of the I-35 Capital Express Central, SH 71 overpasses in Bastrop County, and Loop 360 grade separations in Travis County.
Public Involvement and Feedback
Recognizing the importance of community input, TxDOT encourages public participation in the planning process. Feedback on the Unified Transportation Program (UTP) draft, which introduces $578 million in new funding for San Antonio-area roads, was actively sought, highlighting how community engagement plays a vital role in shaping essential infrastructure projects.
Conclusion
TxDOT’s ambitious 2026 infrastructure projects are poised to reshape Texas’s transportation landscape, significantly enhancing safety, mobility, and accessibility for residents and visitors alike. By fostering an environment conducive to economic growth while maintaining community involvement, Texas is meeting the challenges of today head-on and paving the way for a brighter economic future.
