Putting the final touches on SR 77 from Oro Valley to Tucson

If you’ve driven State Route 77 in Tucson in the past few weeks, you aren’t just seeing the results of a big improvement project, you’re also feeling it.

That’s because ADOT finished work earlier this month to replace 9 miles of worn and rough pavement with smooth new asphalt, nearly wrapping up a $34 million improvement project that’s been underway since early 2021. 

But there are a few improvements yet to be made beyond the pavement. Work crews will be in the area at times through the summer to wrap up final project details. On the roadway itself, that work includes installing permanent lane striping toward the end of August.

Most of the other work is off the road itself. That will involve installing signs and guardrail, along with some curb work, painting handrails and completing drainage improvements.

The SR 77 project spanned Oracle Road from Calle Concordia to Miracle Mile, and Miracle Mile from Oracle to Interstate 10. ADOT maintained access to all 1,100 businesses along the route through the project, and that will remain the case for these finishing touches.
