State Route 89A Improvements

The Arizona Department of Transportation will begin making improvements to SR 89A located through the Oak Creek Canyon switchbacks within the Coconino National Forest in summer 2014.

The work will include milling the existing asphalt and repaving from milepost 386.60 to 390.07, replacing and improving guardrail, repairing the Pumphouse Wash bridge deck and "rock scaling," or rock-fall mitigation.

What to Expect

To complete the work in a safe and timely manner, SR 89A will be closed up to five weeks to all traffic, except emergency vehicles, between Pine Flat Campground and Oak Creek Vista overlook between Memorial Day and July 4, 2014.

In addition to the full closure, there will be other lane restrictions needed, including single-lane closures for work the entire time of the project.

A single-lane restriction will be maintained at either end of the full closure to allow access to both the Pine Flats Campground on the southern end and the Oak Creek Vista overlook at the northern end. Drivers must turn around at the closure points (either the campground or the overlook) at either end. DPS will be on-site.

Emergency vehicles will have access through the work zone to reach residential, recreational and business areas.

Signage and message boards will be used in advance of the closure to ensure traffic is properly detoured via State Route 179 to Interstate 17.
