The warning seems dire enough: Anchorage’s docks could start closing in about nine years due to corrosion and obsolescence, and possibly sooner if there is another big earthquake.
Corrosion in some of the 36-inch steel piles that support the dock is so bad that the steel wall thickness on some piles is down to less than one-eighth of an inch, said Steve Ribuffo, director at the port.
Luckily, the port’s piling seems to have withstood the Nov. 30 earthquake, but that is based on only preliminary inspections. A more complete examination will be done this spring when the ice is gone and there will be better light and tide conditions.
