SR 89A Sedona City Limits to Bear Howard Dr Pavement Preservation Safety Improvement Project

The Arizona Department of Transportation, in coordination with the Federal Highway Administration and the U.S. Forest Service, is beginning an $8.2 million pavement preservation and safety improvement project on 12 miles of State Route 89A just north of Sedona in Oak Creek Canyon (mileposts 374-387). Crews will remove and replace the top three inches of pavement in both directions of the highway; replace more than 30,000 feet of guardrail; and remove trees identified as roadside hazards from both sides of SR 89A.  Work is scheduled to begin early September and is expected to be complete in fall 2020.

SR 89A north of Sedona has experienced rapid degradation due to significant winter weather conditions in recent years. This project will not only extend the life of the pavement, but also improve safety for all highway users by installing guardrail to meet current safety standards and making turnout modifications. Because SR 89A is a designated scenic corridor, the project team is committed to maintaining visual consistency through the entire length of the project.

Hazard Trees

  • Hazard trees are generally identified as dead or dying; pose a danger of falling into the roadway because of high winds, unstable soil or other factors; or otherwise can cause harm to life or property.
  • Removing hazard trees improves safety in the following ways:
    • Improves sight distance at cross roads, driveways and along curves.
    • Establishes open areas so drivers may see wildlife attempting to cross the roadway.
    • Keeps vehicle recovery areas clear of fixed hazards.
    • Removes unhealthy or dead trees that pose a threat of falling onto the roadway due to high winds, unstable soils or other reasons.
    • Prevents snow drifting and reduces ice on the roadway due to shading from trees too close to the pavement.
  • The approximately 700 hazard trees identified for removal as part of this project range in size from small/young to large.
  • Utility crews will also carry out hazard tree-removal work this fall, through permits issued by ADOT to improve safety near utility lines.

What To Expect

  • ADOT advises drivers to expect significant delays and allow extra travel time.
  • Tree removal work will occur 7 a.m. to 7 p.m., Mondays through Fridays, beginning in early September and continuing for about six weeks. Motorists are advised to expect lane closures and travel delays.
  • Pavement preservation work will occur overnight between 7 p.m. and 7 a.m., Sundays through Thursdays, beginning early October and continuing for about two months. During pavement work, SR 89A will be reduced to one lane only. A pilot car will escort alternating traffic through the work zone and direct traffic at crossroads and driveways.
  • ADOT will maintain access of businesses and residences while work is underway.
  • Drivers should use caution around construction personnel and equipment.
