Ina Road Update: Jan 8

I-10 WB - Bridge  demo 1.5.18.jpg

Everyday more progress is being done on the Ina Interchange Project. Last month eastbound traffic was moved from the old roadway to the new surface and that paved the way for the old roadway to be dismantled.

Last week crews finished demolishing the old bridge at Ina Road. In its previous incarnation I-10 travelled over Ina Road. Now, Ina Road will travel over I-10 and the Union Pacific Rail Road, making it safer as and faster. It is similar to the project at Prince Road.

With the old bridge down, the new bridge can be completed. The bulk of the bridge on the west side of the freeway is complete, and eastbound traffic travels under the structure.

Another milestone in the project will be met by the end of January as westbound traffic will move to the new eastbound pavement. This will allow three lanes in both directions until the project is complete. Once the westbound traffic is moved the bridge and new westbound pavement can be completed.

When the work is complete in early 2019, I-10 will have four lanes in each direction, Ina Road will be two lanes in each direction and there will be two bridges over the Santa Cruz River west of I-10, each carrying two lanes of traffic.

ADOT is overseeing the $128 million project, which is funded by the Federal Highway Administration, the Pima Association of Governments and the Regional Transportation Authority. The town of Marana is contributing $7.9 million toward the cost of the new Ina Road bridges over the Santa Cruz River.
