Ina Road Traffic Interchange Construction Moves into Second Phase

The I-10/Ina Road Traffic Interchange project in Marana just north of Tucson has entered the next phase of construction in preparation for the traffic interchange construction at I-10 and Ina Road. The following work is scheduled beginning this weekend:

  • Ina Road will be narrowed to one lane between I-10 and Silverbell Road from 7 p.m. to 6 a.m. Sunday, Jan. 29, through Wednesday Feb. 1. Traffic will be alternated to the open lane. Work crews and traffic devices will guide drivers through the work zone.  
  • Beginning Wednesday morning, Feb. 1, and continuing through fall of 2017, traffic on Ina Road will be shifted to the north side of the road and the roadway will be narrowed to one lane in each direction between I-10 and Silverbell Road.
  • Access to the intersection of I-10 and Ina Road is scheduled to close Wednesday, Feb. 15, barring weather-related or other unforeseen delays. Ina Road, east and west of I-10 will remain open and access will be maintained to all businesses in the work zone for the duration of the project.
  • Massingale Road is closed at the westbound I-10 frontage road through late 2018 while the frontage road is reconstructed. Drivers should use Camino de Oeste instead.
  • The project also includes reconstruction of the Ina Road bridges over the Santa Cruz River. This work has closed the Pima County Loop Trail, south of Ina Road at Ted Walker Road and north of Ina Road at the Crossroads at Silverbell District Park, for approximately two years. Once the bridge project is completed, there will be Loop Trail underpasses on each side of the Santa Cruz River, new bike lanes and sidewalks along Ina Road, and ramps to Ina Road that are compliant with the Americans with Disabilities Act.

The interchange reconstruction project will improve traffic flow in the area. 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
