A motor vehicle incident shut down southbound I-45 at the Griggs entrance ramp early Saturday morning at 12:46 AM, creating a major backup in the predawn hours.
Responding officers worked to clear the wreckage and reopen the affected lanes. The incident occurred under clear skies with temperatures around 81 degrees — conditions that typically wouldn't factor into crash risk, but speed control remains the leading cause of collisions at this location.
This crash is the latest in a troubling pattern at Exit 43A. According to LTA data, the corridor logged 51 incidents over the past 30 days, with 27 of those classified as major. Over 90 days, the count reaches 177 total incidents — 84 major. In the past 12 months, this single interchange has recorded 274 total incidents, including 135 major collisions and 3 fatalities.
State crash records paint a stark picture of the underlying patterns here. Per TxDOT CRIS public crash records, the corridor has logged 1,430 crashes since January 2020. Contributing factors as recorded by the investigating officer show "Failed To Control Speed" cited in 399 of those crashes — nearly 28 percent of all collisions documented at this location. Hit-and-run incidents account for 12.0 percent of all vehicle units involved here, well above typical corridor averages.
Timing at Exit 43A varies considerably throughout the day. The single busiest hour is 4–5 PM, which recorded 12 crashes in recent data, though collisions occur at varied times rather than concentrating in one window. This early-morning incident fits that pattern — crashes here don't follow a predictable rush-hour rhythm. Historically, Sundays see the highest incident count at this location, with 25 crashes recorded over the 90-day period.
For context, Harris County as a whole processed 17,928 incidents over the past 30 days, including 21 fatalities. Exit 43A's incident rate — 51 in 30 days — makes it a persistent flashpoint on the Gulf Freeway corridor.
The roadway was brought back into service following standard incident clearance. Motorists using I-45 southbound in the predawn hours should expect residual delays to clear within the next cycle.
