A project to improve the ride on Interstate 17 between State Route 74 and Anthem Way is scheduled to start June 22, state transportation officials said.

Work on the $15.1 million effort to resurface the freeway and make other improvements will occur during overnight hours. It will not require any immediate lane restrictions along I-17.

Instead, crews initially will work on cross street sidewalks and replace guardrails near the Anthem Way interchange, according to the Arizona Department of Transportation.

No full closures of I-17 are planned as the project moves along, but drivers should expect on- and off-ramp closures at times, ADOT officials said. In August, crews will start resurfacing work at night by removing a top layer of the existing I-17 pavement and replacing it with fresh asphalt. 

The project will also resurface on- and off-ramps and seal bridge decks, replace signs and guardrails, maintain highway shoulders install drainage pipes and provide new pavement markings, a release stated.

ADOT anticipates the work to be completed by spring 2026. The project is funded through the federal National Highway Performance Program.
