A major crash brought traffic to a standstill on IH-45 Gulf northbound at W Dallas Street on Thursday, February 26, 2026, at 3:07 PM, creating significant delays during the critical afternoon commute window.
The incident struck during peak traffic hours, when thousands of commuters typically funnel northward through downtown Houston toward Spring, The Woodlands, and beyond. Drivers heading north on the Gulf Freeway faced substantial backup extending well into Midtown and the Museum District area. Those looking to bypass the gridlock should consider using US-59 northbound as an alternative, or diverting east to I-10 toward I-610 North. Surface streets like Austin Street and Fannin Street provided additional escape routes for downtown-area traffic, though those roads also experienced heavy congestion as drivers sought workarounds.
This section of IH-45 Gulf near downtown is one of Houston's busiest corridors, serving as a critical artery for north-south traffic throughout Harris County. The area around W Dallas Street marks the transition between downtown proper and the Museum District, with major intersections and on-ramps creating natural chokepoints during rush hour. The Gulf Freeway typically handles upward of 200,000 vehicles daily at this location, making even minor incidents capable of triggering widespread delays across the regional network.
The northbound lanes remained affected as of the afternoon's final commute push, with cleanup and recovery efforts underway. Drivers should expect residual delays as traffic flows were restored and the roadway was cleared. Evening commuters planning to head north through downtown should allow extra travel time and monitor real-time traffic conditions before heading out.
