A serious-injury vehicle collision has shut down a stretch of Houghton Road near Interstate 10 Friday morning, authorities said.
Both directions of travel on Houghton Road between Andrada Road and Dawn Road is shut down. The crash occurred south of I-10, said Sgt. Pete Dugan, a Tucson police spokesman.
At least one person was seriously injured.
Drivers should use an alternate route, including Wentworth Road to travel north and south, Dugan said.
An estimated time to reopen the road was not released.
