A video update on the I-10/Ina Road project, six months in

By Tom Herrmann / ADOT Communications

As you drive by Ina Road on Interstate 10, high above where Arizona Department of Transportation crews have been working hard in the dirt below, it’s been a little hard to see the progress our crews have been making on this massive project.

That’s all changing.

At the sixth-month point of this project, several things should catch your eye. The video above highlights those.

We’ve poured cement on a bridge that in a few months will carry Ina Road over the Santa Cruz River. That will allow us to remove and replace the old bridge. A year from now we’ll have two bridges carrying traffic over the river and through the desert, doubling the capacity of Ina Road west of I-10.

Closer to I-10, huge cement pillars are in place to hold a new bridge that will carry Ina Road traffic over I-10 and the Union Pacific Railroad tracks. Girders will be placed on those pillars next month so we can build the western half of that bridge.

Looking east from I-10, more than a dozen 30-foot tall towers of steel rebar have been cemented into place. They will become the support structures for the eastern half of that same bridge over I-10 and the railroad tracks.

Barring something unexpected, we’ll be moving I-10 traffic to new eastbound lanes and beginning work on the east side of the freeway shortly after the first of the year. A year later, in early 2019, you’ll have a wider I-10, wider Ina Road, near bridges over the Santa Cruz River and no more delays as trains make their way north toward Phoenix and south toward Tucson.
