Final Flyover Ramp Opens at Loop 1604 and I-10 Interchange
The $463 Million Project Aims to Ease San Antonio Traffic
San Antonio, Texas – The Texas Department of Transportation (TxDOT) has marked a significant milestone with the recent completion of the final flyover ramp at the Loop 1604 and Interstate 10 interchange. This essential infrastructure, which opened at 5 a.m. on February 5, 2026, connects westbound Loop 1604 to westbound I-10 heading towards Boerne, facilitating smoother traffic flow in an area known for congestion.
The completion of this ramp is part of a larger $463 million project dedicated to enhancing traffic conditions and accommodating San Antonio’s expanding population. The interchange now boasts a total of eight flyover ramps, initiated to streamline connections between Loop 1604 and I-10, showcasing a commitment to improving daily commutes for residents and visitors alike.
A Comprehensive Expansion Effort
This project was launched as part of TxDOT’s Loop 1604 North Expansion Project, which began in 2021. The overarching goal is to widen Loop 1604 from four to ten lanes between SH16 (Bandera Road) near Helotes and I-35 in Universal City. Additionally, it includes the reconstruction of the Loop 1604/I-10 interchange, transitioning from a previous cloverleaf design to a more effective five-level stack interchange. These upgrades are crucial in supporting the region’s economic growth by reducing travel times and fostering better access to businesses and neighborhoods.
The construction of the flyover ramps began with the first one opening in December 2024, followed by additional ramps being unveiled between June and November 2025. Each new ramp has progressively enhanced the operational capability of the interchange. The completion of the upper-level ramp system marks a pivotal moment for traffic management in this heavily traveled area.
Impact on Local Traffic
With the introduction of the final ramp, drivers can now seamlessly access the new flyover on westbound Loop 1604 just past Lockhill-Selma Road, entering the westbound main lanes of I-10 beyond La Cantera Parkway. This development is anticipated to significantly alleviate congestion around the interchange, as drivers benefit from a more efficient route while also contributing to potential economic activity in the vicinity, particularly within the thriving commercial district near The Rim.
As the region continues to experience robust growth, infrastructure improvements like these play a vital role in supporting local entrepreneurs and businesses. Improved traffic flow can lead to increased customer access for small businesses, thereby fostering a resilient economic environment.
Future Developments
While the completion of the flyover ramps is a significant achievement, the project is not fully complete. Ongoing work on the lower-level infrastructure and frontage road enhancements is expected to continue until 2027. As these improvements progress, TxDOT encourages residents to stay informed on potential traffic impacts by following their updates on social media platforms and the official TxDOT website.
The ongoing enhancements along Loop 1604 contribute to a broader vision of a connected and economically vibrant San Antonio. Such developments underscore the importance of strategic planning and investment in infrastructure that responds to community needs.
Conclusion
As San Antonio navigates its growth trajectory, the completion of the Loop 1604 and I-10 interchange’s final flyover ramp reflects a community poised for progress. These efforts exemplify the entrepreneurial spirit inherent in our city, encouraging local businesses to thrive. Residents and visitors alike can expect a more efficient travel experience—a vital step as we collectively support the continued economic prosperity of San Antonio.
Supporting local businesses and staying engaged in developments like these will help ensure a prosperous and connected future for our community.
