ADOT Reopens State Route 87 After Landslide

The Arizona Department of Transportation (ADOT) today has reopened State Route 87. The highway was closed in both directions on Good Friday after a landslide created unsafe conditions in the Slate Creek area (milepost 224). Drivers will travel through a work zone with one lane in each direction and a reduced speed limit as they pass through the area affected by the landslide. "Our team has moved quickly since the landslide to make State Route 87 safe for motorists and restore this critical link between Northern Arizona and the Phoenix area," said ADOT Director Victor Mendez. The decision to reopen State Route 87 was made after thorough inspections, removal of unstable soil and assessments by ADOT engineers who have been at the site of the landslide since it occurred. The northbound lanes have been determined to be safe for drivers, meaning one lane in each direction will use this side of the highway to pass through the Slate Creek area. Motorists will travel through a two-mile long construction zone with one lane in each direction. The speed limit on State Route 87 will be reduced to 45 miles per hour through the work zone. Motorists must slow down and drive safely through the work zone. After touring the construction zone with ADOT engineers, Payson Mayor Bob Edwards said, "I witnessed first hand how fast ADOT is working to safely restore this section of highway which is vital for Payson's economy." The landslide caused sections of the highway's southbound lanes to buckle and shift, creating unsafe driving conditions. In cooperation with the U.S. Forest Service, ADOT will keep this side of the highway closed for an extended period while construction crews excavate and flatten the slope where the landslide occurred. Crews also will reconstruct the southbound lanes damaged by the landslide. Driver safety continues to be the first priority for ADOT. As the highway reopens, crews will continue to monitor the roadway and slope for additional movement or other safety concerns. ADOT will monitor pavement and soil movement laterally and vertically through GPS coordinates, 3D laser scanners and underground devices. ADOT appreciates the patience and understanding of drivers who have been detoured between the Phoenix area and Payson. We ask for continued patience in the coming weeks as repairs are made to State Route 87. The Arizona Department of Transportation (ADOT) began repairing an embankment along northbound State Route (SR) 87 between Sunflower and Rye, in the Slate Creek area, on Monday March 24. Winter storms that produced large amounts of rain caused an embankment and wall to fail between milepost 224 and milepost 225 on SR 87. ADOT immediately took action to limit the damage by placing temporary concrete barriers that kept soil from eroding onto the roadway. Crews have placed message signs to warn motorists, and additional concrete barriers that will separate work crews from motorists throughout the project. Lane restrictions will be kept to a minimum but it will be necessary to narrow the northbound section to one lane. Just prior to the Memorial Day weekend crews will remove the barriers and temporarily halt work, so motorists can travel unrestricted for the holiday weekend. The project should be completed by mid-June. ADOT's Motor Vehicle Division has approved a 12-foot maximum wide load restriction for both northbound and southbound lanes beginning Monday and running through Memorial Day. This will prevent vehicles with wide loads from blocking the construction zone and slowing other motorists. The U.S. Forest Service has partnered with ADOT to ensure proper drainage, erosion control and environmental stewardship throughout the project. ADOT advises motorists to proceed with caution, obey all posted speed limit signs, and be alert for construction equipment and personnel.
