A significant crash brought southbound traffic to a crawl on the West Sam Houston Tollway near Richmond Avenue at 4:57 p.m. on Tuesday, March 24, 2026. Fort Bend County authorities responded to the incident, which occurred during the tail end of the afternoon commute when the tollway typically sees heavy volume heading toward Sugar Land and points southwest.
Commuters heading south through this corridor should expect substantial delays lasting at least several hours. The West Sam Houston Tollway is a major artery for people traveling from central Houston to Sugar Land, Missouri City, and Stafford, making afternoon collisions particularly disruptive. Drivers looking to bypass the affected stretch might consider taking Bellaire Boulevard westbound or US-59 southbound as alternatives, though both routes will likely experience increased traffic as drivers divert. Those heading to the airport or points further south should add significant time to their commutes or wait for the all-clear from traffic management.
The Richmond Avenue intersection marks a critical junction on this section of the tollway. It's one of the busier crossings in the Sugar Land area, with heavy traffic feeding to and from the nearby commercial districts and residential neighborhoods. This particular stretch of the West Sam Houston Tollway sees consistent congestion during peak hours, particularly between 3 and 6 p.m., as commuters head outbound from Houston. The proximity to major employers and retail centers in the immediate area means the tollway carries a steady stream of through-traffic even outside traditional rush periods.
TranStar reported the incident was still being cleared as of late afternoon. The southbound direction bore the brunt of the impact, with backup extending well northbound toward the Beltway 8 interchange. Drivers using this stretch Tuesday evening should plan for extended travel times and monitor traffic updates from local stations for information on when lanes fully reopen.
