A motor vehicle incident struck I-10 outbound at the Washington entrance ramp in Harris County at 1:47 AM on Saturday, April 25, 2026. The incident was classified as major severity.
Mist and reduced visibility—4.0 miles at the time of the crash, with a temperature of 76°F—marked conditions at the location during the incident.
The incident occurred in a corridor experiencing extreme heat. Over the past 30 days, the location at I-10 outbound westbound near the Washington entrance ramp has recorded 42 total incidents, including 17 classified as major. The 90-day incident count stands at 147 total incidents, with 73 major. This concentration reflects a sustained pattern of repeated crashes at this specific merge point.
Historically, this corridor's incident activity skews toward off-peak hours. Over a 90-day window, 37 percent of incidents here occur during rush hour, meaning the dominant pattern occurs outside traditional commute windows. Crash incidents represent the most common incident type at this location over the past 90 days.
The Saturday timing placed the incident outside the traditional weekday rush period. Harris County, which encompasses the greater Houston area and surrounding jurisdictions, recorded 18,620 total incidents over the same 30-day period, with 41 classified as fatal.
The data indicates a persistent structural vulnerability at this merge point. The Washington entrance ramp serves as a high-frequency collision zone independent of time of day, suggesting factors related to the geometry, sight lines, or traffic flow dynamics of the ramp itself may be contributing to the repeated incidents.
LTA's 30-day corridor heat analysis classifies locations with 16 or more incidents in a rolling 30-day window as extreme. This location exceeds that threshold significantly and has maintained that classification across multiple rolling periods.
