Major Motor Vehicle Incident on I-45 North at Airtex Exit Ramp in Houston — Sunday, March 22, 2026

A major motor vehicle incident brought traffic to a crawl on northbound I-45 near the Airtex exit ramp early Sunday morning. Houston Fire Department responded to the scene at 1:24 AM, finding a significant collision that would impact the commute for hours to come. The incident occurred in a critical stretch of the interstate that funnels traffic between downtown Houston and the northern suburbs.

The timing of this crash—just before the early morning commute—created substantial backups on I-45 northbound. Drivers heading toward The Woodlands, Conroe, or points north faced major delays as lanes were reduced. Commuters had several alternatives available, including taking US-59 north or shifting to local roads like the Hardy Toll Road, though those routes also experienced heavier-than-normal traffic as drivers rerouted. The Eastex Freeway offered another option for those with flexibility in their travel plans, though it runs parallel to the affected corridor and would see its own volume spike.

The Airtex corridor represents one of the busier segments of I-45 north, serving as a primary gateway out of Houston's metro core. This stretch regularly handles heavy commercial traffic alongside commuter vehicles, making any incident here particularly disruptive to the region's transportation network. The exit ramp itself feeds into a busy commercial and industrial area, meaning the incident affected not just through-traffic but also local business deliveries and early-shift workers.

The northbound direction bore the brunt of the incident's impact. Houston FD remained on scene managing the response, with the exact status of lanes and clearance time still being determined in the early morning hours. Drivers who had to navigate this corridor Sunday morning experienced significant delays, and the ripple effects extended to connecting freeways throughout north Harris County as traffic diverted to alternate routes.
