Houston-area roadways saw a dramatic surge in traffic incidents over the weekend of March 27-29, 2026, with authorities responding to a total of 3,132 incidents across three days, according to traffic data. Major crashes accounted for 1,810 of those incidents, underscoring the severity of conditions that challenged drivers throughout the region. Harris County bore the brunt of the congestion, accounting for 2,866 incidents, while Fort Bend County reported 181 incidents and Montgomery County documented 53 incidents. Several outlying counties, including Galveston, Brazoria, Milam, Waller, Burleson, and Grimes, reported significantly lower numbers.
The weekend's traffic troubles escalated progressively, with Friday recording 1,272 incidents and 739 major crashes. Saturday proved to be the most problematic day, with 1,055 total incidents and 599 major crashes, including a significant multi-vehicle collision on IH-10 Katy Eastbound at Gessner Drive and another major crash on IH-10 Katy Westbound at SH-6. Sunday rounded out the troublesome weekend with 805 incidents and 472 major crashes, though activity remained elevated compared to typical traffic patterns. The data reveals that Friday's incident count, while highest overall, suggests that Saturday experienced a higher concentration of severe accidents relative to total incidents.
A notable pattern emerged throughout the weekend: the vast majority of incidents occurred during late evening hours, with clusters of crashes reported between 11:27 PM and 11:59 PM across all three days. This suggests that nighttime conditions—potentially including reduced visibility, driver fatigue, and increased speeding—played a significant role in the elevated accident rates. Critical incidents included a major crash at the intersection of Almeda Genoa Road and Randolph Street late Sunday evening, and multiple collisions concentrated on major thoroughfares including Sam Houston Parkway, Hillcroft Avenue, and various Interstate 10 segments.
While freeway incidents dominated the weekend's most serious crashes, surface streets throughout Houston's core also experienced substantial congestion. The concentration of major incidents on I-10, I-45, and Sam Houston Parkway underscores the vulnerability of the region's primary arterial routes during peak traffic periods. Traffic officials recommend that weekend travelers remain vigilant during evening commutes and consider alternative routes when possible.
Drivers are urged to exercise caution on Houston-area roadways and to stay updated on real-time traffic conditions through local traffic management centers and navigation applications. The Texas Department of Transportation and local law enforcement continue to monitor conditions closely as spring weekend travel patterns persist.
