A major collision shut lanes on I-45 near McKinney Street around 11:48 AM on Monday morning, adding to one of the busiest stretches in Harris County.
Responding officers worked to clear the wreckage and move traffic, but the backup was immediate. This intersection has become a flashpoint for crashes in the Houston area — 61 incidents in the past 30 days alone, according to LocalTrafficAccidents.com data. Over the past year, this location has seen 562 total crashes, including 294 major incidents and three fatal collisions.
The timing here is revealing. While the single busiest hour at I-45 and McKinney is 4–5 PM (averaging 15 crashes), collisions occur at varied times throughout the day and week. This morning's 11:48 AM wreck fits a broader pattern — crashes aren't concentrated in one commute window but scattered across the week.
According to state crash records from the Texas Department of Transportation, the broader corridor (within about a quarter-mile) has logged 1,818 crashes since January 2020. Contributing factors as recorded by investigating officers, per TxDOT CRIS, show "Failed To Control Speed" as the leading factor, cited in 564 crashes. The hit-and-run rate at this location stands at 13.3 percent — 497 vehicles involved in hit-and-run crashes out of 3,735 total units involved.
Monday's conditions were clear — 95 degrees and sunny — so visibility wasn't a factor. The data here speaks to volume and repetition rather than weather-related risk.
If you're traveling on I-45 through downtown during the afternoon, expect heavy traffic as crews worked the scene. Lanes were beginning to reopen by early afternoon, though residual delays persisted along the corridor. The road's capacity at this intersection means even cleared wrecks leave a ripple effect for an hour or more.
This stretch of I-45 remains one of the most incident-dense in the Houston-Galveston region.
