Westbound Interstate 10 east of Tucson to close overnight Nov. 17

First of six planned closures for bridge replacement project will require 67-mile detour

TUCSON – A bridge replacement project on Interstate 10 westbound between Tucson and Benson will require a 67-mile detour from 9 p.m. Tuesday, Nov. 17, to 5 a.m. Wednesday, Nov. 18. Westbound I-10 motorists should expect up to two additional hours of travel time and consider avoiding the stretch if possible, according to the Arizona Department of Transportation.

Eastbound I-10 will remain open.

It’s the first of six planned closures to allow crews to replace the bridge at Davidson Canyon, between State Route 83 east of Tucson (Exit 281) and State Route 90 west of Benson (Exit 302).

Detour signs will guide westbound I-10 motorists south on SR 90 (Exit 302), west on SR 82 to Sonoita and north on SR 83 to reconnect with I-10 at Exit 281.

The $15.1 million bridge replacement is in Davidson Canyon, approximately 20 miles east of Tucson. It includes repaving three segments of I-10, totaling approximately 17 miles between Tucson and Benson.

The six full westbound closures are needed to allow crews to set girders and pour new bridge decks. The project is replacing a bridge built in 1961 near milepost 285.

ADOT will provide advance notice of subsequent closures, which will all be overnight and will not affect weekend or holiday travel.

ADOT advises drivers to proceed through the work zone with caution, slow down and be alert for construction equipment and personnel.

ADOT works to inform the public about planned highway restrictions, but there is a possibility that unscheduled closures or restrictions may occur. Weather can also affect a project schedule.
