A major crash closed I-45 southbound at Woodlands Parkway and Robinson Road at 3:01 AM on Wednesday, September 23, 2026, snarling traffic during the early morning hours.
The incident forced crews to shut down southbound lanes while emergency responders worked the scene. The closure backed up traffic significantly on one of Harris County's busiest freeway corridors—I-45 handled over 14,000 incidents in the past 30 days alone, according to LocalTrafficAccidents.com data.
