The I-10/Ina Road Traffic Interchange project in Marana just north of Tucson continues its first phase of construction, in which Ina Road remains open while crews finish building a traffic detour for drivers to use when the Ina Road traffic interchange closes. Work includes drainage improvements and major utility work.
Drivers should proceed through the work zone with caution, slow down and watch for construction personnel and equipment while the following closures and restrictions are in place:
Interstate 10 Frontage Road
- The eastbound I-10 frontage road south of Ina Road and north of Starcommerce Way is reduced to one lane daily through the end of the year.
- The westbound I-10 frontage road is closed between Ina and Cortaro roads through the end of the year.
- Access to all businesses will be maintained. Traffic control signs will guide drivers through the work zone.
- Ina Road, just east and west of I-10, is narrowed to one lane through late 2016.
- Ina Road, east of I-10, has left-turn lane restrictions at Camino de Oeste (in both directions) and at Camino de la Cruz (from eastbound Ina Road only) through late 2016 for utility work. Watch for possible U-turn restrictions while work is underway.
- Massingale Road is closed at the westbound I-10 frontage road through 2017 while the frontage road is reconstructed. Drivers should use Camino de Oeste instead.
- The project to reconstruct the interchange fully will improve traffic operations on I-10 and on the Ina Road traffic interchange. The project consists of widening I-10 to accommodate an additional lane in each direction and widening Ina Road from Silverbell Road to Camino de la Cruz.
Managed by ADOT, this project is funded by the Regional Transportation Authority of Pima County. The voter-approved, $2.1 billion RTA plan will be implemented through 2026. Details about the full plan are available at www.RTAmobility.com.
ADOT works to inform the public about planned highway restrictions and closures, but it’s possible that unscheduled impacts might occur because of weather or other factors.
