A two-vehicle collision brought significant congestion to the intersection of W Greens Road and Tomball Parkway on Friday, February 20, 2026 at 11:28 AM. The crash resulted in injuries to occupants and created a traffic bottleneck during the late-morning period when the area typically experiences steady commuter flow heading toward The Woodlands and surrounding business districts.
The incident occurred at a critical juncture where northbound and southbound traffic on Tomball Parkway intersects with W Greens Road, one of the busier east-west corridors in this section of north Harris County. Drivers heading through the area during the incident faced significant delays, with backups extending onto nearby surface streets. Those seeking to avoid the gridlock had several options: commuters traveling north could divert to Kuykendahl Road or Champion Forest Drive, while drivers heading south found relief by using Grogan's Mill Road or staying on local streets through The Woodlands area.
This stretch of W Greens Road and Tomball Parkway serves as a vital connector between residential neighborhoods and commercial centers, handling daily traffic from both local commuters and through-traffic heading toward downtown Houston or northern corridors. The intersection sits in a zone that regularly experiences congestion during peak hours, particularly where Tomball Parkway feeds into the Tomball area proper. Major shopping centers and office parks in the vicinity mean this location handles substantial midday traffic beyond typical morning and evening rush patterns.
Emergency responders reached the scene and worked to clear the roadway. The collision affected traffic in both directions along Tomball Parkway, with the northbound lanes experiencing the heaviest impact. Drivers in the area during late morning and early afternoon should have anticipated extended travel times, with delays potentially backing up onto connecting roads throughout the Tomball area. By afternoon, traffic began returning to more typical Friday patterns.
