HOUSTON – The Greater Houston area faced an exceptionally challenging traffic day on Tuesday, March 3, 2026, with emergency responders handling 916 total incidents across the region, including 367 major crashes and 549 minor incidents. The high volume of traffic disruptions created widespread congestion across multiple freeways and major roadways throughout the evening hours, with particularly severe incidents concentrated in Harris County.
Harris County accounted for the overwhelming majority of reported incidents, with 823 recorded cases, while surrounding counties experienced significantly fewer disruptions. Fort Bend County reported 65 incidents, Montgomery County 20, and Milam, Galveston, Waller, and Trinity counties combined for just 8 incidents. The concentration of traffic problems in the Houston metropolitan area suggests localized weather conditions or rush hour congestion may have contributed to the elevated incident count during the evening commute period.
Among the most serious incidents were multiple fatal traffic collisions reported on major thoroughfares. Significant crashes were documented at the Northwest Freeway near Fairbanks in North Houston, Loop 494 in the southwest portion of the region, and on Lawndale Street near Evergreen Drive. Additional major incidents included collisions on the Katy Freeway, IH-10 East, IH-610 South Loop, and Westpark Tollway, all of which created substantial delays for commuters traveling through those corridors.
Motorists are advised to exercise extreme caution during evening commute hours and consider adjusting travel times to avoid peak congestion periods. Drivers should remain alert for emergency vehicles, reduce speed in heavy traffic, and avoid distracted driving. Those planning to travel on major Houston freeways, particularly IH-10, IH-45, and the Northwest Freeway, should monitor real-time traffic conditions and allow additional time for their journeys.
