The $1.7 million dollar project is located near the Pinal/Pima County line between Tucson and Casa Grande (milepost 232). The existing bridge was built in 1963.

Work began in November 2018 and is expected to run through spring 2019.

Key elements of the project include:

  • Replacing the bridge deck
  • Repairing steel girders
  • Updating the guardrail

The project will require closure of the bridge over I-10 for about four months tentatively starting the night of November 26. During that time, traffic between Pinal Airpark Road and westbound I-10 will need to use alternate routes.

Motorists going from westbound I-10 to Pinal Airpark Road will be directed to the Red Rock interchange (6 miles to the northwest) and back to Pinal Airpark Road using eastbound I-10. Motorists going from Pinal Airpark Road to westbound I-10 will take eastbound I-10 to the Marana Road exit (5 miles to the southeast), where they can access westbound I-10. 

Traffic to and from eastbound I-10 will not be affected.

In addition, I-10 will be reduced to two lanes in each direction during certain phases of the project.

Drivers should proceed through the work zone with caution, slow down and watch for construction personnel and equipment. Expect possible delays and consider alternate routes.
