Phoenix, Arizona — Eastbound lanes of Interstate 10 were shut down at 99th Avenue Monday evening, triggering significant commuter delays in west Phoenix.
According to the Arizona Department of Transportation, the closure was reported around 5:40 p.m. after a spilled load left debris across the eastbound lanes near the 99th Avenue interchange, west of central Phoenix and near the Tolleson area.
ADOT said cleanup crews were dispatched to remove the debris, but as of the latest update, there was no estimated time for reopening the eastbound lanes. Motorists traveling east through the area were advised to expect extended delays and to use alternate routes.
Westbound lanes of Interstate 10 were not affected by the incident and remain open, ADOT confirmed.
The closure impacts a heavily traveled stretch of I-10 that serves daily commuters traveling between the West Valley and downtown Phoenix, particularly during the evening rush hour. Traffic congestion was reported extending several miles west of the closure as drivers were diverted off the interstate.
ADOT did not specify the type of vehicle involved or the nature of the spilled load and said additional details would be released if they become available. No injuries were immediately reported.
Drivers are encouraged to monitor ADOT traffic alerts, check real-time traffic maps, and allow extra travel time when navigating through west Phoenix Monday evening. This corridor is frequently used by young workers and students commuting between Glendale, Tolleson, and Phoenix employment centers.
