A deadly crash earlier today shut down the northbound lanes of Loop 410 at the Highway 151 interchange on San Antonio's West Side, stalling the pre-dawn commute and sending emergency crews racing to the scene. Traffic quickly stacked up as drivers were forced off the loop at nearby exits while investigators worked around the wreckage.
According to WOAI, the collision was reported at about 4:30 a.m. and shut down the northbound main lanes of Loop 410 at the Highway 151 interchange. The outlet shared a TransGuide traffic camera clip that showed emergency vehicles blocking multiple lanes at the junction. Officials told the station that crews remained on scene and that traffic was being diverted around the closure while the investigation continued.
Recent crash history at the interchange
This stretch of Loop 410 has seen serious incidents in recent weeks. On Jan. 20, a woman was struck and killed near the same Highway 151 interchange, according to the Bexar County medical examiner and police. KSAT covered that investigation.
Traffic impacts and what drivers should know
Major collisions at this junction regularly back traffic up for miles and push motorists off at exits like Culebra and the SeaWorld ramps, creating long detours. MySA documented similar diversion patterns during a Jan. 20 closure. Drivers heading through the West Side are urged to allow extra time and follow posted detours and traffic-control directions. Local traffic feeds such as TransGuide and live broadcast updates will carry the latest lane-closure information.
By midmorning, police had not released the names of those involved or an official cause of the crash, and investigators remained at the scene. This story will be updated as agencies provide new details.
