Heavy morning storms on Wednesday turned key Houston freeways into a slog, with crashes and lane closures tangling traffic across the northwest and central corridors. Commuters ran into poor visibility and standing water in low-drainage spots while emergency crews hustled from scene to scene. The morning rush featured long slowdowns on several major routes as tow trucks and cleanup crews worked to clear wreckage. Officials urged drivers to expect delays, take it slow on slick pavement, and give themselves extra room and time.
Which freeways were affected
According to Houston TranStar, a heavy-truck crash shut down all eastbound main lanes on the I‑610 North Loop at McCarty Street, while a separate accident blocked all westbound main lanes on U.S. 290 Northwest after Tidwell Road. The I‑10 (Katy Freeway) eastbound also took a hit near Blalock Road, where frontage-road lanes and an exit ramp were reported closed.
TranStar's incident list, updated at 6:21 a.m. Wednesday, showed crews verifying and clearing several scenes between about 5:00 a.m. and 6:20 a.m. Some closures lingered into the heart of the morning commute, and drivers in northwest Harris County were advised to use alternate routes until lanes fully reopened.
Local reporting and conditions
Local station CW39 reported similar trouble spots and said the I‑610 crash involved multiple big rigs, pointing to heavy rain and ponding in areas with poor drainage. CW39’s update came as part of rolling coverage of the fast-moving storms that kept traffic desks and emergency crews busy across the region. The station urged motorists to steer clear of water-covered stretches and be ready for delays while wreckage was cleared.
Weather snapshot
The National Weather Service's Houston/Galveston office warned that "locally heavy rainfall of 1–3 inches is expected and localized flooding is possible." NWS Houston/Galveston radar showed rounds of thunderstorms pushing through the area overnight into Wednesday, upping the risk of rapid ponding and reduced visibility on high-speed corridors. That short-duration heavy rain can overwhelm drainage in known trouble spots, officials said, creating sudden hazards for drivers. Travelers were urged to plan for lingering impacts during the morning commute.
Where to get updates
Officials reminded motorists not to drive through standing water: "Turn Around, Don't Drown." They also asked drivers to move over for tow trucks and first responders.

Travelers should allow extra time for commutes and consider delaying nonessential trips until conditions improve.
