ADOT begins work on 89A north of Cameron

CAMERON, Ariz. - The Arizona Department of Transportation (ADOT) has started work on improvements to a nine mile segment of U.S. 89 at Moenkopi Wash, beginning about 10 miles north of Cameron and continuing north about five miles past the junction of U.S. 89 and U.S. 160.

The project includes new pavement and striping, new guardrail, shoulder and drainage improvements.

Work will take place Monday through Thursday during daylight hours, with some night work to occur during the paving portion of the project. Drivers can expect reduced speeds and lane restrictions at various locations during work hours. Flaggers will guide vehicles through the work zone.

This project is scheduled to finish in the fall of 2014.

Work to widen U.S. 89 to four lanes through Cameron, a primary travel route that connects Flagstaff, southern Utah and popular tourist destinations in the Page/Lake Powell region is also ongoing.

U.S. 89 runs through the community of Cameron within the Navajo Nation, approximately 50 miles north of Flagstaff.

During construction ADOT will expand U.S. 89 to two lanes in each direction between State Route 64 and the Little Colorado River (mileposts 464-467). The construction also includes the removal and replacement of the existing U.S. 89 Cameron Truss Bridge, which was built in 1959, with two new bridges at that location.

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

ADOT expects the two major phases of construction to be complete by the fall of 2016. During phase I of construction, all traffic will remain on the current alignment. During phase II, ADOT will move all traffic onto the newly constructed roadway, which ADOT expects to be completed by the summer of 2015.

U.S. 89 between Bitter Springs and Page is currently closed because of a Feb. 20, 2013 landslide, with construction on the emergency repair of the roadway expected to start in early summer of 2014, if there are no environmental, utility or right-of-way hurdles. The repair on this section of the roadway is currently estimated to cost $25 million. The project will include moving the roadway about 60 feet toward Echo Cliffs and using that rock to construct a down slope buttress to stabilize the area.

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

With the reconstruction of the landslide-damaged portion of U.S. 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.
