A major crash closed IH-610 West Loop northbound at W 18th Street early Wednesday morning, backing up traffic across the inner loop and forcing commuters to find alternate routes.
The wreck happened at 2:36 AM on Wednesday, July 29, 2026. Harris County fire and law enforcement crews responded to the scene and worked to clear the roadway.
With the northbound lanes blocked, traffic that normally flows freely on the loop in the pre-dawn hours got bottlenecked. If you're heading north on 610 during the early morning commute, expect residual congestion even as crews work to reopen the affected section.
Surface streets paralleling the loop offer relief—Westheimer, Richmond, or Bellaire heading west; Irvington or Fulton heading north. These routes add travel time but will get you moving if 610 is still sluggish by the time you hit the road.
According to LocalTrafficAccidents.com data, crashes are the most common incident type on this section of the loop over the past 90 days. Harris County as a whole recorded 17,439 incidents in the past 30 days, including 29 fatalities.
Check traffic apps for real-time conditions before you leave. Crews typically clear major incidents on the loop within a few hours, but early-morning wrecks can trap commuters if you're not monitoring conditions closely. The loop should reopen as crews finish their work, but give yourself extra time if you're heading through this area Wednesday morning.
