West Sam Houston Tollway crash at Tanner Rd; 39 incidents in 90 days

A crash on West Sam Houston Tollway northbound at Tanner Road brought traffic to a halt Thursday morning around 9:28 AM, adding to a stretch of the corridor that's seen significant incident activity in recent months.

The wreck blocked lanes and backed up traffic during what should have been a lighter part of the morning commute. Responding officers worked to clear the scene, though exact clearance time wasn't immediately available.

This crash marks the latest in a notable pattern at this location. According to LTA data, the West Sam Houston Tollway northbound at Tanner Road has recorded 39 total incidents over the past 90 days—31 of them major. In just the last 30 days alone, seven incidents have occurred here, six classified as major. Looking at the longer view, Texas Department of Transportation crash records show 420 crashes within about a quarter-mile of this corridor since January 2020, with no fatalities in that span.

Thursdays appear particularly active at this location: the 90-day data shows 13 incidents recorded on Thursdays. While the corridor experiences crashes at varied times throughout the day rather than concentrating in a single peak window, the single busiest hour historically is 4 to 5 PM, which has recorded four crashes.

Contributing factors as recorded by investigating officers, per TxDOT CRIS, show "Failed To Control Speed" as the most common factor at this corridor, cited in 157 crashes since 2020. The hit-and-run rate here stands at 7.5%, with 67 of 893 units involved in crashes fleeing the scene.

Conditions at the time of this morning's incident were clear—broken clouds and 82 degrees—so weather wasn't a factor in this particular wreck.

The road should reopen once debris is cleared and lanes are confirmed safe. If you're heading through the area, expect residual delays until crews finish their work.
