An oil spill has closed a portion of West Orange Grove Road in Marana Monday afternoon.
Westbound lanes on Orange Grove are closed between Camino de la Tierra and Interstate 10, said Sgt. Chris Warren, a Marana Police Department spokesman, in a tweet about 3 p.m.
The spill is expected to be cleaned and the road re-opened in a few hours, police said.
Motorists are asked to use alternate routes.
No further information is immediately available.
