I-45 northbound crash at Sam Houston Parkway; 36 incidents in 30 days

A crash shut down northbound I-45 at the Sam Houston Parkway entrance ramp early Saturday morning, adding to what's become a persistently troubled stretch of highway in north Harris County.

The wreck happened at 2:45 AM on July 11. Responding officers cleared the roadway, but the incident underscores a pattern that's hard to ignore: this exit has been the site of 36 crashes in the past month alone, according to LocalTrafficAccidents.com data.

Over the past 90 days, the location has recorded 90 total incidents, with 54 classified as major. In the past year, that number climbs to 155 incidents, 90 of them major crashes. The data shows this isn't a sporadic problem—it's a recurring one.

Weather conditions at the time of the early-morning crash were clear, with few clouds and a temperature near 78 degrees. Despite favorable conditions, the crash still occurred at a location where speed-related issues have been historically significant. According to TxDOT CRIS public crash records, the corridor near this exit has recorded 1,386 crashes since January 2020, with "Failed To Control Speed" listed as the most common contributing factor in 558 of those incidents.

LTA data shows that while crashes at this exit occur throughout the day and week, the busiest hour for incidents is 5-6 PM, though crashes happen at varied times rather than concentrating in just one window. Mondays have historically been the highest-incident day at this location, with 13 crashes recorded over the past 90 days.

The intersection sits in Harris County, which recorded 18,244 total incidents over the same 30-day period that saw 36 crashes at this single exit—a concentration that reflects the location's outsized share of regional traffic incidents.

For drivers heading northbound on I-45 in the early morning hours, this stretch continues to demand extra caution. The roadway has since reopened to normal flow.
