I-45 northbound major crash at Tidwell; 33 incidents in 30 days

A major crash brought I-45 northbound to a standstill at the Tidwell exit ramp around 10:27 AM on Thursday, June 18, snarling traffic during a stretch of the freeway already dealing with extraordinary crash frequency. Responding officers worked the scene as backups built through the corridor during mid-morning hours.

The crash hits a location that's become a persistent flash point on the north Harris County freeway. According to LocalTrafficAccidents.com data, the I-45 northbound corridor near Tidwell has logged 33 incidents in the past 30 days—16 of them major crashes. Over the past 90 days, the location has recorded 148 total incidents, including 74 major crashes and one fatal. That pace is starkly different from the broader Harris County picture: the county saw 18,319 incidents in the same 30-day window, with just 15 fatals.

This particular location has been caught in a cycle of serious collisions. Texas Department of Transportation crash records from January 2020 to the present show 1,571 crashes within about a quarter-mile of this spot, resulting in 7 fatalities. Among all crashes recorded here by investigating officers, the most commonly cited contributing factor was "Failed To Control Speed"—accounting for 712 crashes over that six-year span, per TxDOT CRIS public crash records.

The timing of incidents here is scattered rather than concentrated into one predictable window. While the single busiest hour is 5–6 PM (with 11 crashes), collisions occur throughout the day. Thursday morning's wreck is a reminder that this interchange carries risk across the clock.

Conditions at the time of the crash were scattered clouds and 91 degrees—clear weather, with no adverse conditions contributing to the incident. However, the sheer volume of crashes at this location over recent weeks underscores the sustained pressure on this corridor.

Traffic was being diverted as crews cleared the wreckage. Motorists heading northbound were advised to avoid the immediate area and seek alternate routes during cleanup. No estimate was immediately available for full clearance, though the major classification suggests the closure extended into the late-morning hours as lanes were being reopened.
