Project to expand and improve I-17 north of Phoenix Advances

PHOENIX (AP) – State transportation authorities have begun negotiating with a construction and engineering consortium on a massive project to expand and improve Interstate 17 in the hill country north of Metro Phoenix.

The Department of Transportation said it has selected the Keiwit-Fann joint venture from among three finalists as an “apparently preferred developer” to make improvements to the 37-kilometer I-17 between Anthem Way and. to design, build, operate and maintain sunset point.

The project is designed to help reduce the clutter of traffic on the freeway that connects the Phoenix Metro to the Prescott, Sedona and Flagstaff areas and the Verde Valley to the north.

A key component will be the construction of 8 miles (13 kilometers) of new two-lane road that will be adjacent to the current interstate lanes south, but will be used for either south or north traffic as appropriate.

ADOT said the final cost will be determined after contract negotiations, but that $ 362.5 million in funding from the state and other sources has already been secured for the project.

Once there is a final contract, planning and construction is slated to begin in 2022, with construction being completed in about three years, the department said.
