Multi-vehicle crash during icy weather closes northbound Loop 1604 at Marbach Road in San Antonio

Closure impacts a key Far West Side corridor amid widespread winter travel hazards

A major multi-vehicle crash shut down northbound Loop 1604 at Marbach Road on Sunday, January 25, 2026, forcing traffic off the highway and onto nearby access roads as crews responded to hazardous conditions.

The collision involved seven vehicles and was reported at about 10:20 a.m. in the northbound lanes near Marbach Road. Authorities said ice on or near an overpass contributed to the crash, which occurred during a period of freezing temperatures affecting roadways across the region.

Following the wreck, lanes on the highway were closed and drivers were diverted away from the affected stretch. Transportation officials indicated the closure was expected to remain in place into the afternoon, with an estimated reopening time around 2:45 p.m. No major injuries were reported.

Regional context: winter weather and cascading traffic disruptions

The Loop 1604 closure unfolded as wintry weather contributed to additional roadway disruptions elsewhere in and around San Antonio. With temperatures at or below freezing and precipitation creating slick surfaces, traffic incidents were reported across major routes, prompting lane closures and slowdowns. Officials continued emphasizing that overpasses and elevated roadways can ice over first, creating sudden loss-of-traction risks even when nearby pavement appears passable.

For drivers who must travel during freezing conditions, public agencies repeatedly recommend lowering speeds, increasing following distance, avoiding abrupt braking or lane changes, and planning routes that reduce reliance on elevated ramps and bridges when icing is possible.
