Sam Houston Tollway westbound crash in heavy rain Saturday

A major crash brought westbound traffic to a standstill on the South Sam Houston Tollway at SH 35/Telephone on Saturday, June 20, around 11:55 AM. Heavy rain was falling at the time, with temperatures near 81°F—conditions that can make high-speed freeway driving treacherous.

This stretch of the tollway has emerged as a persistent crash hotspot. According to LocalTrafficAccidents.com data, the corridor logged 39 incidents in the past 30 days, with 29 of them rated major—the kind that tie up traffic for hours. Over the past 90 days, the location has seen 98 total incidents, 57 classified as major. Since January 2020, the corridor has recorded 774 crashes in the vicinity of this intersection, per TxDOT CRIS public crash records.

Weather played a role in Saturday's incident. TxDOT reports wet conditions contributed to over 14,000 Texas crashes in the most recent annual reporting period. When rain cuts visibility and reduces tire grip, even routine maneuvers on a busy freeway become high-risk. The timing—midday Saturday—falls outside the typical weekday commute pattern. According to LTA data, the single busiest hour at this location is 2 to 3 PM, but crashes here occur throughout the week.

Historically, Fridays see the most activity at this intersection, with 16 crashes recorded on that day across the past 90 days. Contributing factors as recorded by investigating officers, per TxDOT CRIS, show that "Failed To Control Speed" is the most common notation at this location, appearing in 251 of the corridor's 774 crashes since 2020.

Responders cleared the scene and traffic flow resumed. Drivers heading westbound on the tollway during that stretch should expect residual delays as the roadway returned to normal operations. If you were in the area when this happened, remember that rain-slicked pavement can persist for some time after precipitation ends—roads are still slick out there.
