A major traffic accident shut down Post Oak Boulevard at Garrettson Lane early Sunday morning, creating significant delays during the typically lighter weekend commute. Houston Police Department responded to the crash at 7:13 a.m. on February 22, 2026, with officers securing the scene and beginning their investigation into the collision.
The incident struck during the morning hours when Post Oak Boulevard typically carries steady traffic from the Uptown area toward downtown and the Texas Medical Center. Drivers heading through the Uptown corridor should expect significant backups along Post Oak between Westheimer and San Felipe, with delays potentially extending 20 to 30 minutes. Those traveling northbound or southbound through the area have several alternatives: drivers can divert to nearby Sage Road, which runs parallel to Post Oak and offers a less congested route, or take Westheimer Road to access surface streets heading toward their destination. Vehicles traveling to the Medical Center can use South Braeswood or Hermann Drive as bypass routes.
Post Oak Boulevard remains one of the busier thoroughfares in the Uptown area, handling substantial traffic volumes even on weekends. The stretch near Garrettson Lane sits directly in the heart of Houston's upscale Uptown neighborhood, with multiple high-rise office buildings, hotels, and retail centers lining both sides of the road. Major intersections nearby include Westheimer and San Felipe, making this a critical corridor for commuters accessing downtown, the Medical Center, and points west. Weekend traffic here rarely reaches weekday congestion levels, making this Sunday morning crash particularly disruptive for early-morning travelers.
Houston Police had the roadway secured by mid-morning, though full details about which direction faced the most significant impact were not immediately released. Cleanup and investigation operations continued through the morning hours as officers worked to clear the scene. Drivers in the area should remain alert for residual congestion and slower-moving traffic as crews complete their work and lanes reopen to normal operations.
