Interstate 17 and JW Powell Traffic Interchange Improvements

Coconino County Fair This Weekend

ADOT is urging motorists headed to the annual Coconino County Fair this Labor Day weekend (Aug. 29 – Sept. 1) to allow extra travel time as traffic delays are expected. The main entrance to the Fort Tuthill County Park along State Route 89A remains closed due to an ongoing improvement project and traffic is routinely backed up onto Interstate 17 and SR 89A during special events at the park.

The park's main entrance at Fairgrounds Road, which intersects with JW Powell Boulevard and SR 89A/Beulah Boulevard, has been closed since early June while ADOT continues construction of the realignment of SR 89A and two new roundabouts at this location.

During the fair, attendees will enter and exit the fairground at two alternate locations north of Fairgrounds Road. The first location is Fort Tuthill Loop, approximately 300 yards north of the main entrance. The second location is at West Purple Sage Trail, which is slightly more than one-half mile north of the main entrance on SR 89A.

Law enforcement officers will be in the area and signage will be placed to guide fairgoers into and out of the park through the holiday weekend.

Project Background

An improvement project to reconstruct the interchange at I-17 and JW Powell Boulevard has begun.

The improvement project will realign State Route 89A / Beulah Boulevard in the vicinity of Fort Tuthill County Park and construct two roundabouts, one at the entrance of the park and the other at the I-17 southbound ramps, to provide a safer transition for traffic through the intersections.
