I-10 Traffic Switches to New Lanes This Weekend Near Tucson

Drivers heading from northwest Pima County toward downtown Tucson will start using new eastbound lanes of Interstate 10 at Ina Road this weekend.

Beginning Saturday night, Dec. 16, Arizona Department of Transportation crews will begin moving eastbound traffic to the new lanes of I-10 as part of a two-year project to improve both I-10 and Ina Road. The work is expected to be complete the morning of Sunday, Dec. 17.

Also on Sunday, about one mile west of the freeway, Ina Road traffic will switch to a new bridge over the Santa Cruz River. This bridge will carry one lane of traffic in each direction while the old bridge is removed and a second new bridge is built in its place.

The I-10/Ina Road interchange project, which remains on schedule approaching the halfway point, will add a lane in each direction to both I-10 and Ina Road and includes a bridge to carry Ina Road traffic over I-10 and the Union Pacific Railroad tracks. The improvements will allow traffic to move more smoothly through the area while enhancing safety.

Westbound I-10 traffic will switch to the new eastbound pavement in mid- to late January. ADOT will maintain three lanes of traffic in each direction until the project is completed in early 2019. When the work is complete, I-10 will have four lanes in each direction, Ina Road two lanes in each direction, and there will be two bridges over the Santa Cruz River, each carrying two lanes of traffic.

I-10 / Ina Road Construction Continues in Arizona

From now through mid-2017, the Arizona Department of Transportation will be constructing a bridge over I-10 and the Union Pacific Railroad tracks at Ina Road. When completed, this project will ease the flow of traffic at this intersection and improve the safety at this location for all users of Marana’s roads and I-10.

The Interstate 10/Ina Road Traffic Interchange project in Marana just north of Tucson continues its first phase of construction and is scheduled to last through early 2017. Work includes constructing a detour for traffic to use when the Ina Road traffic interchange closes, building temporary construction easements and major utility work. During this phase, Ina Road remains open. Drivers should proceed through the work zone with caution, slow down and watch for construction equipment and personnel while the following I-10 closures and restrictions are in place:

  • The left lane on eastbound I-10, from Ina to Orange Grove roads will be closed nightly from 8 p.m. to 5 a.m. Thursday, Sept. 29, through Friday, Sept. 30 and again Sunday, Oct. 2, to Wednesday, Oct. 5.
  • The westbound I-10 frontage road is closed between Ina and Cortaro roads through the end of the year and also closed south of Ina Road through September.
  • The eastbound I-10 frontage road south of Ina Road and north of Starcommerce Way is reduced to one lane daily through fall 2016.

Access to all businesses will be maintained. Traffic control signs will guide drivers through the work zone.

ADOT works to inform the public about planned roadway restrictions, but there is a possibility that unscheduled closures or restrictions may occur due to weather or equipment issues.

Drivers are reminded to share the road, be cautious, and slow down while traveling through the work zone.

I-10 East of Tucson to Close Overnight March 22

The Arizona Department of Transportation reports that a bridge replacement project on westbound Interstate 10 between Tucson and Benson will require a 67-mile detour overnight from 9 p.m. Tuesday, March 22, to 5 a.m. Wednesday, March 23.

Westbound I-10 motorists, traveling toward Tucson, should expect up to two additional hours of travel time and consider avoiding the stretch if possible.

Eastbound I-10 will remain open.

It’s the first of two planned closures this spring 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).

The full westbound closures are needed to allow crews to safely set girders and pour new bridge decks. The concrete girders, which are 119 feet long and weigh 45,000 pounds each, are lifted off truck beds and put in place by a crane.

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 improvement project includes replacing the bridge at Davidson Canyon, which was built in 1961 near milepost 285, and repaving three segments of I-10, totaling 17 miles between Tucson and Benson.

ADOT will provide advance notice of the next closure, which will be overnight during April and will not affect weekend or holiday travel.

Paving work, which is on a winter shutdown, is expected to resume in early April.

Drivers should proceed through the work zone with caution, slow down and be alert for construction equipment and personnel.
