| 摘要： | The need for an additional lock the size of the Poe Lock, at Sault St. Marie, Mich., was first cited by a U.S. Army Corps of Engineers report in 1986 and authorized in the Water Resources Development Act (WRDA). One of the two parallel locks enabling ships to travel between Lake Superior and the Lower Great Lakes, the "lynch pin of the Great Lakes Navigation System" has no backup. An aging and deteriorating infrastructure means unscheduled outages are increasing. |
