Major I-10 crash near The Dominion shuts eastbound lanes, triggering long backups and detours Thursday
Crash closes a key stretch of I-10 on San Antonio’s Northwest Side
A multi-vehicle crash shut down a portion of eastbound Interstate 10 near The Dominion on Thursday morning, February 26, 2026, disrupting one of the region’s busiest commuter corridors and causing extended delays for drivers approaching San Antonio from the west.
Traffic backups were reported beginning shortly after 10:20 a.m. on the eastbound main lanes, with the collision reported around 10:40 a.m. The impacted area was described as spanning the segment between Camp Bullis Road and the La Cantera Parkway area, with congestion stretching back toward Leon Springs during the late morning and early afternoon hours.
Injuries reported; investigation ongoing
Officials said at least three vehicles were involved in the crash. One person was transported to a hospital, though the severity of that person’s injuries had not been released as of Thursday. The circumstances that led to the collision were still under investigation, and early assessments had not definitively established a cause.
Authorities treated the scene as active while responders worked to assist those involved, document the crash, and clear vehicles and debris from the roadway. Initial reports indicated the incident was being evaluated for severity as the investigation continued.
Traffic impacts and driver guidance
The closure forced eastbound drivers off the main lanes and onto frontage roads, creating stop-and-go conditions and significant travel-time increases. With I-10 serving as a primary connection between the western suburbs and central San Antonio, the shutdown affected mid-day traffic patterns well beyond the immediate crash location.
Drivers were advised to anticipate extended delays and to plan alternate routes when possible, especially those traveling into the city from the Boerne area. Commuters were also urged to use caution near the scene as emergency vehicles and tow operations moved through the corridor.
- Location: I-10 near The Dominion, Northwest Side
- Direction affected: Eastbound main lanes
- Vehicles involved: At least three
- Medical response: One person transported to a hospital
Context: A corridor under frequent pressure
The crash occurred in a part of Northwest San Antonio where traffic volumes routinely spike due to commuting, retail and entertainment destinations near La Cantera, and ongoing roadway work in the broader Loop 1604/I-10 interchange area. Even short-term lane closures in this zone can rapidly produce miles-long backups because frontage-road capacity is limited compared with the interstate’s main lanes.
Updates on reopening times and any additional medical or investigative details were still pending Thursday afternoon.
