Roads are in danger of breaking apart near the Overton Wash on the northwest side, Pima County Sheriff's Deputy Tom Peine told Tucson News Now.
The sheriff's department says Overton Road and La Cholla Boulevard are collapsing because of rainfall and construction in the area.
"Drivers who are used to driving in the area after rain need to be careful," Peine said Saturday night. "It's easier to see when it's daylight. It could be dangerous tonight."
Peine said drivers should heed all warning signs and not drive around them.
"Use extreme caution," Peine added.
