US-90A crash at Post Oak ramp; 33 incidents in 30 days

A major crash at US-90A outbound near the Post Oak entrance ramp disrupted early-morning traffic Tuesday when a vehicle collided on the freeway at 4:59 AM, August 18.

Responding officers cleared the scene, but the incident adds to a troubling pattern at this location. According to LocalTrafficAccidents.com data, the Post Oak ramp area has logged 33 incidents over the past 30 days—16 of them major crashes. Over the past three months, that number climbs to 103 total incidents, with 51 classified as major.

The corridor's heaviest traffic hour is between 5 and 6 PM, when crashes peak at 10 incidents per hour. However, crashes here don't cluster neatly into rush hour—they're spread throughout the day and night, which is unusual for freeway segments. This Tuesday's pre-dawn collision underscores that pattern.

State crash records tell part of the story. According to TxDOT CRIS public crash records, the area within a quarter-mile of this ramp has recorded 682 crashes since January 2020. Contributing factors as recorded by the investigating officer, per TxDOT CRIS, show "Failed To Control Speed" as the leading factor, cited in 241 crashes.

Hit-and-run incidents are also notable in the corridor: 13.1 percent of vehicles involved in crashes here leave the scene, compared to the statewide average.

Weather conditions at the time of Tuesday's incident were clear—scattered clouds and 80 degrees—ruling out wet pavement or reduced visibility as factors in this particular crash.

Commuters heading westbound on US-90A should expect residual delays through the morning commute. If you're planning to use the Post Oak ramp during peak hours, consider alternate routes. Traffic typically moves more freely on surface streets in the immediate area, though delays may occur across the broader corridor given its history of incidents.

The road classification as a freeway means crashes here ripple through the region quickly. With 33 incidents in just 30 days, this location remains one of the higher-activity spots in Harris County, which recorded 17,809 total incidents in the same period.
