Interstate 10 westbound is closed south of the Valley at milepost 164, according to the Arizona Department of Transportation.
The closure is due to a crash. There is no estimated reopening time.
Traffic is passing on the shoulder, however backups are expected. To avoid delays, motorists can take State Route 587 north to State Route 87 north. Motorists can then take Loop 202 Santan west to re-enter I-10.
