A major motor vehicle incident blocked traffic on the eastbound Exit 30A ramp of Interstate 610 South near the Waller exit around 9:13 AM on Wednesday, September 23. Responding officers worked the scene as southbound lanes backed up significantly during the mid-morning period.
The crash occurred during what's typically one of the busier hours at this location. According to LocalTrafficAccidents.com data, the 9 to 10 AM window has historically recorded the highest incident count at this exit — three crashes over the past 90 days — though crashes here occur throughout the day rather than clustering in a single rush period.
This incident adds to a growing pattern at the location. Over the past 30 days, eight total incidents have been recorded at Exit 30A, with four classified as major severity — meaning today's crash is consistent with recent activity rather than an isolated event. Over the past 90 days, 27 incidents have occurred at this interchange, including 11 major crashes and one fatal incident, according to LTA data.
Looking at the longer historical record, state crash data from the Texas Department of Transportation shows 252 crashes within about a quarter-mile of this location since January 2020. Contributing factors as recorded by investigating officers, per TxDOT CRIS, show "Failed To Control Speed" as the leading factor, cited in 78 crashes at the corridor. The hit-and-run rate at this interchange stands at 11.3 percent, with 63 of 556 vehicles involved in reported incidents failing to remain at the scene, according to state records.
Weather conditions at the time of the incident were scattered clouds and 91 degrees — clear conditions that did not appear to be a contributing factor. Responding officers cleared the scene, and traffic flow returned to normal.
Drivers using 610 South should expect occasional backups at Exit 30A given the location's incident history. The ramp is a high-traffic interchange serving the Waller corridor, and even routine incidents here tend to create noticeable delays during peak hours.
