18-Wheeler Crash Snarls I-45 South at Exit 32 in Heavy Rain

An 18-wheeler and a black truck collided on Interstate 45 South near Exit 32 around 5:05 AM on Wednesday, May 20, sending a major crash response to the scene in heavy rain. The crash blocked multiple lanes during the pre-dawn hours, backing up southbound traffic as crews worked to clear the roadway.

Harris County emergency personnel responded to the debris-strewn crash site and began clearing lanes. The incident unfolded as heavy-intensity rain fell across the area — conditions that amplified risk on an already volatile stretch of highway. TxDOT reports wet conditions contributed to over 14,000 Texas crashes in the most recent annual reporting period, underscoring how rapidly rain transforms driving conditions on high-speed corridors.

This location sits at the center of a severe crash concentration. According to LocalTrafficAccidents.com data, I-45 South at Exit 32 has logged 30 incidents over the past 30 days — 19 of them major — placing it in the extreme-heat category. Over the past 90 days, the corridor has seen 81 total incidents, including 46 major crashes and 5 fatalities. While this particular crash occurred during offpeak morning hours, the broader data shows most incidents here cluster outside traditional rush windows: the dominant incident time pattern across 90 days is offpeak, with only 34 percent of crashes occurring during rush hours.

The crash added to Harris County's ongoing incident load. The county recorded 19,365 incidents over the past 30 days, including 20 fatalities.

Delays persisted as crews managed lane closures and debris removal. Southbound I-45 traffic experienced significant backup near the exit as emergency response continued. The road was reopened to traffic following standard clearance procedures, though residual congestion lingered into the early morning commute.
