East 15th Avenue is expected to be closed in both directions between Lake Otis Parkway and Orca Street until Friday evening as crews repair a sinkhole, a municipal official said.
Anchorage police issued an alert Thursday morning asking drivers to use another route as municipal street maintenance workers assess the situation. Crews initially responded to a report of a pothole that came in around 6:45 a.m., then discovered it was actually a deeper sinkhole, said municipal Street Maintenance Manager Paul VanLandingham.
An aging pipe below the road separated at its joints and collapsed, he said, which created a void that led to the sinkhole. Crews will replace that section of pipe Thursday night and resume work early Friday, VanLandingham said.
The goal is to reopen the road between 5 and 6 p.m. Friday, he said.
