Beginning Tuesday, motorists on westbound Interstate 10 southeast of Tucson can expect significant delays.
A bridge replacement project on I-10 westbound between Benson and Tucson will require a 67-mile detour from 9 p.m. Tuesday, Nov. 17, to 5 a.m. Wednesday, Nov. 18.
The detour will divert westbound traffic from Arizona 90 (Exit 302), west on Arizona 82 to Sonoita and north on Arizona 83, reconnecting with I-10 at Exit 281.
Westbound I-10 motorists can expect up to two additional hours of travel time and should consider avoiding the stretch if possible, according to the Arizona Department of Transportation.
Eastbound I-10 will remain open.
This is the first of six planned closures to allow crews to replace the bridge at Davidson Canyon, between Arizona 83 east of Tucson (Exit 281) and Arizona 90 west of Benson (Exit 302).
