A major crash shut down westbound I-10 at SH-6 around 5:11 AM on Tuesday, July 21, backing up traffic during the early morning hours and forcing drivers to reroute across the region.
Responding officers found significant damage at the scene. Lanes remained blocked as crews worked to clear debris and move vehicles. The backup stretched for miles in both directions, creating a bottleneck that persisted through the early shift change.
I-610 loop, the Westpark Tollway to the west, and Washington Avenue or Memorial Drive through inner-loop segments all offered alternate routes for westbound travelers. Those heading downtown faced delays on every major approach until the roadway reopened.
