A major crash brought traffic to a crawl on the South Sam Houston Tollway eastbound at IH-45 Gulf Freeway around 10:33 AM on Monday, June 15, as very heavy rain and near-zero visibility made conditions treacherous across Harris County.
Responding officers found the roadway significantly congested with multiple vehicles involved. Heavy rain continued to hammer the area, with visibility dropping to just 0.2 miles. TxDOT reports wet conditions contributed to over 14,000 Texas crashes in the most recent annual reporting period, and Monday's downpour was no exception.
This intersection sits in a corridor with a troubling frequency of incidents. According to LTA real-time data, the South Sam Houston Tollway at IH-45 has recorded 48 crashes in the past 30 days alone. Over the past 90 days, the corridor logged 166 total incidents, with 104 classified as major. The data underscores that this location sees crashes at varied times throughout the day, though the single busiest hour remains 4–5 PM, when the corridor has experienced 14 crashes.
TxDOT CRIS public crash records show an even longer pattern at this intersection. Since January 2020, the corridor has recorded 1,013 crashes within about a quarter-mile, including 4 fatalities. The most common contributing factor recorded by investigating officers is "Failed To Control Speed," which appears in 496 of those crashes. Hit-and-runs also account for a notable share—12.6% of the 2,238 vehicle units involved in crashes here were involved in hit-and-run incidents.
Monday's rain-soaked conditions likely slowed recovery. Emergency crews worked to clear debris and assess the situation while traffic backed up significantly. Drivers heading eastbound should have used alternate routes—the Hardy Toll Road, SH-249 to the northwest, or local routes via Airline Drive were available options to bypass the bottleneck.
The incident was cleared, though exact clearance time was not confirmed. Drivers using this corridor during wet weather should exercise extra caution; the data shows this intersection demands attention regardless of conditions.
