Person struck on Loop 410 near Texas 151 prompts full northbound closure during afternoon rush

Northbound Loop 410 shut down on West Side as emergency crews respond

All northbound main lanes of Loop 410 near the interchange with State Highway 151 were closed Tuesday afternoon, January 20, 2026, after a person was struck by a vehicle in the area, triggering a large emergency response and major rush-hour delays on San Antonio’s West Side.

The incident was first reported shortly after 4 p.m. and unfolded near the elevated sections of roadway under and around the Highway 151 overpass. Traffic cameras in the area showed emergency vehicles positioned across multiple lanes as first responders worked at the scene.

What is confirmed so far

• The incident occurred Tuesday, January 20, 2026, near the Loop 410 and Highway 151 interchange.

• Northbound Loop 410 lanes were closed, with traffic diverted away from the main lanes.

• San Antonio Fire Department crews and law enforcement responded, and the scene required an active investigation.

Conflicting early reports on lane status and injuries

Initial traffic updates described the closure as affecting all northbound lanes. Subsequent roadway status information indicated that at least one northbound lane may have remained open at points during the response, reflecting how lane availability can change as crews reposition vehicles, establish safe working zones, and adjust traffic control.

Authorities had not publicly confirmed the person’s condition or released identifying information by early evening. The circumstances leading to the collision also remained under investigation, with no official determination immediately available on factors such as visibility, speed, impairment, or whether the person was attempting to cross the roadway.

Traffic impacts and driver guidance

The closure quickly created backups and slowed travel approaching the Highway 151 interchange, a key connector for West Side commuters. Motorists were routed off the freeway, with at least one diversion point reported at the Marbach Road exit as crews limited access to the affected stretch.

Drivers were urged to use alternate routes and plan for delays while first responders worked and investigators documented the scene.

Officials did not provide an estimated time for reopening. In incidents involving potential serious injury, reopening can depend on medical response needs, crash reconstruction, evidence collection, and roadway cleanup. Updates were expected as investigators completed on-scene work and traffic control was adjusted.
