Corps: New Soo Lock Project Gets Under Way

The U.S. Army Corps of Engineers will not fund a new lock in Sault Ste. Marie, Michigan, through the Recovery Act (economic stimulus) in favor of projects that could be done much quicker.

But, the Corps will start the lock replacement project this summer by building dams to hold back water to allow excavation and other work. It’s a step needed for lock construction, says John Niemiec, project manager.

Installing the dams with $17 million from Congress will take until fall 2010. The Corps had a groundbreaking ceremony June 30 for the new lock, to be built in the footprint of the outdated Sabin and Davis locks. It will serve as a backup to the Poe Lock, the only one large enough to give 1,000-foot freighters access to Lake Superior.

The Corps chose projects for stimulus funding that it could finish in the next couple of years, John says. The new Soo lock will take eight to 10 years to finish and “will probably need $450 million or more.”
