FLAGSTAFF, Ariz. -- The Arizona Department of Transportation said it could be more than two years before motorists can again travel a now-closed section of northern Arizona highway between Flagstaff and Page.
The department said it plans to rebuild the highway atop a new rock retaining wall at the base of a Feb. 20 landslide where the ground slipped out from under U.S. 89. Cost has been estimated at $40 million. ADOT said it considered building a whole new road around the collapse or repaving the highway where it is now.
The Arizona Daily Sun reported that pre-construction processes will take 12 to 18 months and that construction would take 6 to 12 months.
The paper reported it would take longer to build a whole new road around the collapse.
The detour in use adds 50 miles to the trip. A shorter detour is being prepared.
