To provide the most accurate information about upcoming traffic impacts, the project team will provide as much notice as possible for lane closures and traffic switches. See below for a live map of traffic closures in San Antonio.

Loop 1604 North Expansion lane closures

Throughout construction of these improvements, drivers will experience temporary traffic shifts and overnight lane closures on the mainlanes and frontage roads, as well as temporary daytime and overnight ramp closures.

Daytime work is anticipated to take place 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.

Permanent and temporary digital message boards placed along the route will alert drivers in real-time to lane closures, traffic congestion and construction activity.

This page is updated weekly. To find the most up to date and current lane closures, follow us on the San Antonio TxDOT Facebook and X pages or visit the San Antonio District’s Go Ahead! Blog
