Sedona SR 89A Switchbacks Reduced to Single Lane

ADOT photoSedona AZ (May 1, 2015) Motorists traveling on Arizona State Route 89A between Sedona and Flagstaff should allow for extra travel time as the Arizona Department of Transportation starts a project next week to improve erosion protection along the eastern bank of Oak Creek at milepost 385, just south of the switchbacks.

Beginning on Monday, May 4, 2015, SR 89A will be reduced to one lane during the daytime, Monday through Friday, from the early morning hours to 4:00 p.m. while northbound and southbound traffic alternates driving through the work zone.

No night time, weekend or holiday work is anticipated.

state route sr 89a road signThe repair to the creek bank will fortify support to the roadway and prepare for strong storm water flows expected during the monsoon season. Following last yearÂ’s Slide Fire in Oak Creek Canyon, water flow in Oak Creek is expected to increase and if so will undermine the east bank of Oak Creek and roadway support at this location without the scheduled improvement work.

The bank protection work is anticipated to be fully completed this summer.

Flaggers will be on-site to provide alternating north and south bound travel through the work zone. Please allow for extra travel time as delays up to 15 minutes can be expected while work is performed.

  1. State Route 89: Hell Canyon Bridge Replacement about 18 miles North of Chino Valley

    The Arizona Department of Transportation and the Federal Highway Administration are planning a bridge-replacement project for the Hell Canyon Bridge on SR 89, approximately 18 miles north of the town of Chino Valley, Arizona.

    Construction to replace and remove historic Hell Canyon Bridge is expected to begin in early 2015. A new four-span steel plate girder bridge will be constructed to the east of the existing bridge, which will remain open during the 16-month construction time frame.

    Motorists should be prepared for brief delays while traveling through the work zone. The first phase of the project will include constructing the new Hell Canyon Bridge. Temporary access roads will be built along the north and south sides of the canyon to assist with bridge construction and removal.

    Once construction of the new bridge is complete, traffic will be switched to the new structure. The existing bridge will be dismantled and removed, which is expected to take two to three months.
