ADOT begins work on US 89 widening project near Cameron

Bridge over Little Colorado River to be replaced, new roundabout added
March 07, 2014

PHOENIX — The Arizona Department of Transportation has started a project to expand US 89 from two lanes to four lanes through the community of Cameron within the Navajo Nation, approximately 50 miles north of Flagstaff. 

Major work on the $36.7 million project includes widening US 89 to two lanes in each direction between State Route 64 and the Little Colorado River (mileposts 464-467) and removal and replacement of the existing US 89 Cameron Truss Bridge, which was built in 1959, with two new bridges at that location.

Additional improvements on US 89 through Cameron include constructing a roundabout at the existing intersection of US 89 and SR 64, new sidewalks, streetlights, and four pedestrian/livestock underpasses.

Construction is anticipated to be completed in two major phases with completion expected fall 2016.

Traffic delays may occur during construction with traffic reduced to one lane. There will be directional signage and flaggers present during construction. ADOT advises motorists to be alert for construction equipment and personnel, and to proceed through the work zone with caution.

US 89 is the primary travel route that connects Flagstaff, southern Utah, and the popular tourist destinations in the Page/Lake Powell region. US 89 between Bitter Springs and Page is currently closed due to the Feb. 20, 2013 landslide.

Motorists traveling on US 89 between Page and Flagstaff can bypass the landslide closure by using the newly paved, 44-mile-long US 89T route that runs parallel to US 89 from The Gap to LeChee. US 89T is the former Navajo Route 20 that connects with US 89 approximately 17 miles north of the US 160 junction (Tuba City exit).

With the reconstruction of the landslide-damaged portion of US 89 not expected to start until early this summer, ADOT, along with the Navajo Nation and Federal Highway Administration, pursued paving Navajo Route 20 (which became the US 89T route) to serve as a short-term solution.
