Houston Traffic Week in Review: 7,239 Incidents Mark Busy March as Weekend Congestion Peaks

Houston area roadways experienced significant congestion during the week of March 2-8, 2026, with traffic management officials documenting 7,239 total incidents across the greater metropolitan region. Among those incidents, 2,783 were classified as major crashes, underscoring persistent safety concerns on some of the nation's busiest highways. The data reveals a consistent traffic burden throughout the week, with weekend days matching or exceeding weekday congestion levels—a pattern that defies typical commuting expectations and suggests sustained regional congestion regardless of the day.

Saturday emerged as the busiest day of the week with 1,163 total incidents, including 483 major crashes. Friday followed closely with 1,160 incidents and 445 major crashes, while Sunday recorded 1,160 incidents with 401 major crashes. The weekend's elevated traffic levels stood in stark contrast to Monday, which proved to be the calmest day of the week with 838 incidents and 349 major crashes. Thursday and Tuesday also saw relatively lighter traffic, recording 966 and 955 incidents respectively. This inverse pattern—where weekends rival or exceed weekday congestion—suggests that recreational travel, commercial logistics operations, and construction-related activities may be contributing factors beyond traditional rush-hour commuting patterns.

Harris County dominated the week's traffic incidents, accounting for 6,664 of the 7,239 total incidents reported across the region. This represents approximately 92 percent of all traffic activity tracked during the period. Fort Bend County followed distantly with 418 incidents, while Montgomery County reported 104 incidents. The remaining counties—Galveston (35), Milam (8), Liberty (4), Waller (3), Brazoria (2), and Trinity (1)—collectively accounted for less than one percent of regional traffic incidents. The overwhelming concentration of traffic in Harris County reflects the greater Houston metropolitan core's population density and serves as a critical reminder of the infrastructure demands placed on this region's transportation network.

Several serious incidents during the week highlighted ongoing safety concerns on major thoroughfares. A multi-vehicle crash with injuries at I-45 South and Broadway Street was reported multiple times throughout the week, suggesting this intersection experienced repeated collision activity. A white Kia overturned following a crash at I-610 East and Broadway Street, while a white Ford Explorer was involved in a freeway collision at US-59 North and Westpark Drive. Additional significant incidents included a rollover on Highway 506 North Clay Road, a major vehicle crash at Southmore Boulevard and Emancipation Avenue, and multiple motor vehicle incidents at the I-45 outbound and Broadway exit ramp area. The frequency of incidents at these locations warrants heightened driver vigilance and potential infrastructure review.

Geographic clustering of incidents reveals concerning patterns in specific corridors. The I-45 corridor—particularly near Broadway Street and the Howard exit ramp—emerged as a particular hotspot for traffic incidents throughout the week. Similarly, the intersections of major east-west arteries in south Houston, including Southmore Boulevard, demonstrated repeated collision activity. These concentration points suggest potential issues ranging from inadequate signage and lane markings to congestion-related bottlenecks that may require traffic engineering intervention or enhanced law enforcement presence.

As the greater Houston area continues to experience robust population growth and commercial activity, drivers are urged to exercise heightened caution, particularly during weekend periods when congestion rivals weekday levels. Motorists should allow additional travel time, maintain safe following distances, and remain alert for sudden traffic disruptions—especially in known incident-prone corridors. Traffic management officials encourage commuters to utilize real-time traffic applications and consider alternate routes during peak periods. Additionally, drivers should reduce speeds in areas experiencing active incidents and be prepared for unexpected lane closures. With major crash activity consistently exceeding 300 incidents daily, safety remains paramount on Houston's roadways.
