In May 2018, the Texas Department of Transportation awarded a $108.9 million contract to construct mainlane improvements along an approximately 6.7 mile section of Interstate 10 East, from I-410 to Loop 1604, in San Antonio, Texas.
Construction of this three-year project began in October 2018. Once complete, the project will improve safety and mobility and reduce congestion by:
This project complements other ongoing construction in the area to improve overpasses and shift from two-way to one-way frontage road access, as well as proposals to widen the entire I-10 corridor between San Antonio and Houston to six lanes.
Construction Impacts to Traffic
As currently planned, the freeway will be reconstructed and widened in segments, with initial work focused on construction of new temporary pavement on the shoulders of both eastbound and westbound lanes near the I-410 interchange. While a minimum of two travel lanes in each direction will be maintained throughout the construction period, motorists will experience temporary traffic shifts and overnight lane closures.
Permanent and temporary digital message boards placed along the route will alert motorists in real time to lane closures, traffic congestion, and construction activity.
Daytime work is anticipated to occur Mondays through Saturdays, while nighttime work and any necessary lane closures are anticipated to take place between 9 p.m. and 5 a.m., Sunday evenings through Friday mornings.
Work Zone Safety
Roadway work zones can be hazardous, both for workers and motorists who drive through the complex array of signs, barrels and lane changes. Please keep the following tips in mind when driving through work zones:
