Western Rock Products is working on the Bitter Springs to Fredonia Highway (US 89A) Project located in Coconino County in North-Central Arizona. Valued at $8.1M, this 15-mile highway rehabilitation project will provide safer mobility for those traveling through the area by incorporating an intermittent climbing lane and updating the roadway surface.

The project limits begin at an elevation of 6,000 ft., approximately 16 miles south of Fredonia, Arizona, and ascends to 8,000 feet into the Kaibab National Forest, ending at the Jacob Lake Inn, located at the North Rim and gateway of Grand Canyon National Park.

Work activities include incorporating an intermittent climbing lane and performing a 2-inch mill & fill. Crews worked to place a glass grid geogrid reinforcement in a test section before paving 2-miles of the highway.

Due to the weather restrictions, construction will resume in the Spring of 2023 to hot apply the chip seal application, supplied by a portable hot plant, and place the final pavement markings.

“Western Rock’s project team and the supporting operations groups have risen to the challenges & headwinds faced when working with a non-typical DOT entity. It takes coordination with people working tirelessly & timely to progress a portable plant/mill & fill highway project; throw in a transportation broker to boot!” – Joe Wilden, CM – Western Rock Products.
