Two people were killed early Thursday in a wrong-way rollover crash at the Interstate 35 and Interstate 37 interchange near downtown San Antonio. The wreck happened at about 2:30 a.m., and first responders tried to rescue one of the drivers, but both were pronounced dead at the scene. San Antonio police said a woman was traveling the wrong way when her vehicle collided with another car, and investigators have opened a probe.
According to WOAI, officers arrived to find both vehicles heavily damaged at the interchange while emergency crews worked the scene before it was cleared. The station reported that authorities have not yet released the victims' names or additional details about what led up to the crash.
Interchange history and traffic
The I-35 and I-37 connector ramps form a tight weave of lanes just north of downtown, and the area has a history of serious wrecks that can quickly choke off traffic. A multi-vehicle crash in March shut down parts of I-35 at the I-37 junction and snarled commutes for hours, according to MySA.
Wrong-way driving and safety measures
Wrong-way crashes most often happen at night and are frequently tied to impairment or driver confusion, a risk TxDOT has highlighted in its safety research. The department and regional mobility authorities have tested lower-mounted “Wrong Way” signs and reflective pavement markings to help reduce ramp-entry mistakes, a countermeasure detailed in a TxDOT mobility release.
SAPD's traffic investigators remain on the case and the department has not yet released additional information, WOAI reported. The investigation is ongoing.
