Major crash closes southbound U.S. 281 at San Pedro Avenue, triggering widespread North Side delays

Southbound lanes closed near a key North Side junction

A major traffic crash shut down southbound U.S. Highway 281 at San Pedro Avenue in San Antonio on Sunday morning, Feb. 22, 2026, disrupting one of the city’s primary commuter routes between the North Side and central San Antonio.

Transportation officials reported the incident at about 10:15 a.m., with multiple southbound lanes affected at the interchange area near San Pedro Avenue. As the response unfolded, the shutdown expanded into a full closure of southbound lanes in the immediate area, prompting drivers to seek alternate routes.

Congestion quickly extended beyond the crash scene

Real-time traffic monitoring during the closure showed severe slowdowns, with speeds dropping to single digits and delays reaching roughly 20 minutes in the heaviest congestion. Backups spread northward along the U.S. 281 corridor, affecting access to and from nearby arterial roads and ramps that typically serve as relief valves for freeway incidents.

Because U.S. 281 functions as a major spine for North Side travel, even short-notice lane closures can cascade into wider delays on parallel routes as drivers divert. The shutdown near San Pedro Avenue also complicated movement through an area already sensitive to bottlenecks created by closely spaced entrances, exits, and ramp merges.

What is known—and what remains unclear

By late morning, authorities had not released details on what caused the crash. Information on injuries, the number of vehicles involved, and whether any enforcement or reconstruction activity was required at the scene had not been confirmed publicly at the time of initial reports.

Officials urged motorists to avoid the area while crews worked, a standard request when lanes are blocked and responders need space to provide medical care, secure vehicles, clear debris, and restore safe traffic flow.

Why this location is especially disruptive

The U.S. 281 and San Pedro Avenue area sits within a broader network of high-volume connections that feed commercial centers and residential neighborhoods. When a crash forces closures here, detours often push traffic onto frontage roads and nearby surface streets, where signal timing and limited turning capacity can rapidly create secondary backups.

Drivers’ checklist during major freeway closures

• Use alternate corridors early rather than waiting near the backup, where turnaround options can be limited.
• Expect delays to persist after lanes reopen due to residual congestion and merging friction.
• Give emergency vehicles additional room and avoid stopping on shoulders unless directed.

Drivers were advised to take alternate routes as the southbound closure remained active Sunday morning.

The duration of the closure and the timeline for full reopening were not immediately confirmed in initial public updates, and additional details were expected as the investigation and cleanup progressed.
