It won’t be done in time for this year’s Tucson Gem & Mineral Show, but Arizona Department of Transportation officials are getting close to showing off a widened two-mile section of Interstate 10 here in Tucson.

Commuters will soon be able to travel on four lanes in each direction between Ruthrauff and Prince roads.

A spokesperson for the state agency said work is in the final stages of the $76.4 million project designed to increase capacity, reduce congestion and improve traffic flow.

ADOT broke ground on the project in September 2011.

A new bridge over Prince Road, which will eliminate the at-grade crossing for Union Pacific Railroad lines, is expected to improve traffic flow at the intersection.

Some lane restrictions and ramp closures will begin in February, according to ADOT, in order to shift traffic onto the new westbound I-10 lanes.

The final delay will come in late April or early May, when state crews go back to repave the project area one final time.

ADOT is waiting until late spring for ideal temperatures in order to complete the project.

Down the Road
  • The Pima County Department of Transportation has extended the time frame on a crack-sealing project along Sabino Canyon Road, between Cloud and Kolb roads.

Work has been extended until Tuesday evening, and traffic will be reduced to one lane of travel in each direction.

  • A county project along Hacienda del Sol between Sunrise Drive and River Road is also taking longer than expected. Work has been extended through Tuesday evening.

Lane restrictions will be in place during construction.

  • The county will also be activating a new traffic signal on Orange Grove Road and Camino de la Tierra on Tuesday.

Traffic will be directed through the work zone by a Pima County sheriff’s deputy, and motorists should expect delays.


Q: Jim Kit writes that he knows Green Valley is low on Pima County’s list of repairs, but has concerns about Esperanza Boulevard.

“The 1/4 mile of westbound approach (Esperanza Blvd) to I-19 is in very bad shape,” he writes. “There are more than 20 potholes in that short stretch to I-19. It is impossible to avoid them, and cars swerve in and out of lanes to try to avoid (them.)”

A: Priscilla Cornelio, the director the Pima County Department of Transportation, offers some good news.

“This segment of Esperanza is scheduled as part of our Pavement Preservation Program for (this) fiscal year for a mill/fill two-inch asphalt overlay,” she said.

While there is no date on when the project will start, staff anticipates the work will break ground before June 30.

A tipster tells the Road Runner that there is also a work order to fill the potholes along Esperanza in the coming days.
