A crash on the North Sam Houston Tollway westbound at Wilson Road shut lanes down Thursday afternoon and backed up traffic during the middle of the day. The wreck happened at 1:36 PM on September 10, and responding officers worked to clear the scene.

The crash is the fourth major incident on this stretch of the tollway in just the past 30 days, according to LocalTrafficAccidents.com data.

Harris County saw 16,153 incidents across the county in the past 30 days, with 23 of those fatal. But this particular corridor on the North Sam Houston Tollway is running well above typical frequency. Across a full 12 months, 20 crashes have been recorded at this same location, 13 of them major.

Contributing factors as recorded by the investigating officer, per TxDOT CRIS, show "Failed To Control Speed" as the leading factor, cited in 297 crashes at the corridor.
