TUCSON - Drivers are being urged to avoid the area around the Canada del Oro Wash, between Overton Road and Magee Road in the northwest side.
Pima County Sheriff's Department Deputy Tom Peine says the roads are shut down.
The roads are in danger of collapsing because of the recent rain and construction.
Earlier Saturday morning, crews rescued a man stuck in the CDO wash at Overton Road.
They helped him get out of the car, but his car is still stuck there.
He was not hurt.
