SAN ANTONIO – Drivers traveling through the Loop 1604 and Interstate 10 interchange should prepare for major closures this weekend as crews continue work on the Loop 1604 North Expansion Project.

The Texas Department of Transportation will close the eastbound and westbound Loop 1604 main lanes at I-10, along with the eastbound and westbound I-10 main lanes and I-10 frontage roads at Loop 1604.

The closures are scheduled to begin at 9 p.m. Friday, Aug. 21, and continue through 5 a.m. Monday, Aug. 24, weather permitting.

All flyover ramps at the Loop 1604 and I-10 interchange will remain open.

Drivers on Loop 1604 will be directed to exit before the interchange, travel along the frontage roads and re-enter the highway at the first available entrance ramp.

Drivers traveling on I-10 will detour using the Loop 1604 flyovers and frontage roads. Drivers traveling on the I-10 frontage roads will also be redirected through nearby turnarounds, including La Cantera Parkway and Vance Jackson Road.

TxDOT is asking drivers to follow posted detour signs and allow extra time when traveling through the area.
