A major crash on I-10 westbound at Washington Avenue brought traffic to a halt early Tuesday morning, April 07, 2026, at 12:54 AM. The collision involved multiple vehicles and forced authorities to close lanes on one of Houston's most critical east-west corridors during the overnight period.
The incident struck during a typically lighter traffic window, but the westbound closure immediately created backups extending several miles behind the crash site. Drivers heading toward Katy or points west faced significant delays, with traffic being diverted onto surface streets including Washington Avenue itself and alternate routes through nearby neighborhoods. Local commuters familiar with the corridor shifted toward US-59 or the feeder roads to bypass the slowdown, though even those routes showed signs of congestion as drivers sought passage around the disabled vehicles.
The I-10 corridor at Washington Avenue has emerged as one of Harris County's more problematic stretches in recent weeks. Over the past 90 days, the intersection has logged 59 major incidents among 117 total crashes—a stark reminder of the challenges this busy thoroughfare presents, particularly during hours when visibility is reduced and driver fatigue may be a factor. This section of I-10 marks a critical juncture where traffic from the Houston Ship Channel area converges with westbound commuters, creating a complex merge pattern that has repeatedly proven treacherous.
Westbound lanes remained affected through the pre-dawn hours as recovery crews worked to clear the scene. The exact clearance time was not immediately available, but crews were actively removing the vehicles and debris that had blocked travel. Drivers heading into the central business district or toward the western suburbs faced extended commute times as the incident unfolded and cleanup operations continued.
For anyone planning travel in the area during the morning commute, delays persisted in the westbound direction. The backup from this overnight collision had the potential to affect the start of the Tuesday morning rush, with residual congestion likely lingering even after the initial lanes reopened.
