A motor vehicle incident shut down the exit ramp at Exit 121B on southbound US-59 near the Westpark exit early Saturday morning. The crash happened at 4:35 AM on October 10, 2026, with clear skies and temperatures around 69 degrees.
Authorities responded to clear the roadway. Lane and clearance details weren't immediately available, but the incident added to a troubling pattern at this stretch of freeway.
This exit ramp sits at one of the region's most crash-prone locations. According to LTA data, the Exit 121B corridor logged 23 incidents over the past 30 days—14 of them major. Over the past 90 days, the count climbs to 91 total incidents, including 55 major crashes and 3 fatalities. State records paint an even starker picture: since January 2020, TxDOT CRIS data documents 1,976 crashes within about a quarter-mile of this location, resulting in 11 fatalities.
Saturdays are the single busiest day here. LTA data shows 14 of the corridor's 90-day incidents occurred on Saturdays—more than any other day of the week. Most crashes here fall outside weekday commute peaks, but when they do cluster, it's between 8 and 9 PM.
Contributing factors as recorded by investigating officers, per TxDOT CRIS, show "Failed To Control Speed" as the leading factor, cited in 766 crashes at this location. Hit-and-runs occur in 12.6 percent of crashes here—518 of the 4,117 vehicles involved fled the scene.
Harris County recorded 11,768 incidents in the past 30 days, including 2 fatalities. This single exit ramp accounts for a fraction of the county's overall incident load, but its frequency relative to its limited geography underscores why crews and drivers know it well.
The Saturday-morning timing of this incident fell outside the corridor's typical 8-9 PM peak, but that offered little consolation to early-morning travelers navigating around the closure. As of publication, the roadway status and expected clearance time were not yet confirmed. Motorists heading south on US-59 should monitor real-time traffic conditions and consider alternate routing if delays persist.
