ADOT reconstructing I-17 intersection at JW Powell south of Flagstaff

Project will realign SR 89A, add roundabouts near Fort Tuthill County Park
June 03, 2014

PHOENIX – In order to provide a safer flow for traffic, the Arizona Department of Transportation will realign State Route 89A and reconstruct the intersection of southbound Interstate 17 and JW Powell Boulevard three miles south of Flagstaff.

Crews began construction of new alignments of SR 89A, and southbound on- and off-ramps at JW Powell Boulevard near Fort Tuthill County Park and Flagstaff-Pulliam Airport on June 2.

The project will also include the construction of roundabouts at the entrance to the park and the southbound I-17 ramps. The roundabouts will help facilitate the safer flow of traffic through the area, and will be designed to meet current and future traffic demand.

Drivers can expect restrictions and lane closures throughout construction.

Preparations for this project began last September when ADOT worked closely with Coconino County, the city of Flagstaff and the local utility company to remove trees to allow space for project construction while saving as many trees as possible. The area will be re-seeded with native vegetation once the project is complete.

The project is anticipated to be complete by summer 2015.
