In a matter of days, drivers used to stop-and-go traffic on Loop 1604 on San Antonio’s rapidly growing Northwest Side will find some relief.

Work is just about complete to convert the section from Bandera to Culebra roads into a four-lane expressway with new overpasses at the intersections of Braun, New Gilbeau and Shaenfield roads.

Minus stop lights, the two southbound lanes are expected to open as early as Monday, and the two northbound lanes will likely be ready within three weeks after that.

“The southbound lanes are the priority,” said Texas Department of Transportation spokesman Josh Donat. “Once those lanes are in and done, the northbound lanes are going to get hit really hard. All of the contractor’s assets will be working on those northbound lanes.”

TxDOT built new frontage roads on either side of the highway to allow drivers access to the intersections below the overpasses.

It’s also working on a flyover to connect southbound Loop 1604 and eastbound Texas 151 and a direct connector between Texas 151 and Alamo Ranch Parkway, a $44 million undertaking that won’t be complete until later this year.
