June 23, 2026 at 06:40 AMBy Dennis R. Mundy, Executive Editor📍 Harris County

A major crash at South Loop W and Timberside Drive backed up traffic on Tuesday morning. The wreck happened around 6:40 AM, just before the workday rush.

The intersection sits on one of Harris County's busier crash corridors. According to LocalTrafficAccidents.com data, this location has logged 16 incidents over the past 30 days, with 13 of those classified as major. Over the past 90 days, the count climbs to 42 total incidents, 25 of them major. In the past year alone, responding authorities have documented 62 crashes at this intersection.

Tuesday's timing placed the incident outside the intersection's typical peak window. LTA data shows most crashes here occur outside standard weekday commute hours, with the single busiest period falling between 9 and 10 PM—a pattern that points to evening congestion rather than morning rush impact. That said, any major wreck at 6:40 AM will catch drivers heading into the start of their day.

Weather conditions were clear at the time of the crash, with temperatures around 81 degrees. Road conditions appear not to have been a contributing factor.

The broader context matters here. Texas Department of Transportation crash records covering this corridor since January 2020 show 358 total crashes in the area, with speed control cited as the most common contributing factor—121 crashes recorded as "Failed To Control Speed," per TxDOT CRIS public records. Over that same period, hit-and-run incidents accounted for 14.3 percent of all crashes at this intersection.

Authorities cleared the scene and traffic returned to normal flow. Drivers should remain alert in the area, particularly during evening hours when this intersection's crash frequency peaks.

**Update (7:45 AM CT):** The major crash at 3498 S LOOP W @ 9499 TIMBERSIDE DR, first reported at 6:40 AM, has cleared after approximately 1 hour and 5 minutes. All lanes have reopened and normal traffic flow has resumed in the area.
