Intersections remain a common place for crashes in San Antonio, but they are making up a smaller share of the overall total. Since 2022, intersection crashes as a percentage of all reported crashes have declined consistently each year from 18.7% in 2022 to 18% in 2025. As of May of this year, they stand at 17.5%.
Still, nearly one in five San Antonio crashes happened at an intersection in 2025, according to an Express-News analysis of Texas Department of Transportation crash data. That’s more than 8,400 crashes. In the first five months of 2026, there were about 3,000 crashes at intersections.
Crashes at the 10 most dangerous intersections on all regular streets and roads in San Antonio — excluding freeways, expressways, and ramps — accounted for 132 crashes and resulted in 129 injuries last year.
Topping the list is East Bitters Road at Heimers Road, just north of the airport and east of U.S. 281. In 2025, there were nine crashes resulting in 16 injuries — one of them serious. The primary cause of crashes at the multi-lane intersection is drivers failing to yield the right of way when turning left. Other factors included driver inattention and ignoring the light.
Driver inattention was a top factor for crashes at many other intersections, contributing to one in four crashes. Other common factors included disregarding traffic signals or stop signs and failing to yield the right of way.
As part of its most recent five-year safety plan, TxDOT has adopted Intersection Control Evaluation, a process meant to help transportation officials choose the safest and most effective design for an intersection or interchange. The process compares options based on safety, traffic flow, cost and community impacts, and is intended to push planners to consider alternatives beyond traditional signals and stop signs. Those options can include roundabouts, reduced-conflict U-turns and other designs meant to reduce crash risks by limiting conflict points and keeping traffic moving without requiring every vehicle to stop.
None of the top 10 most dangerous intersections, however, has been rebuilt or adapted to one of those alternative designs.
