Page 10 Aerial view of the American Locks at Sault Ste. Marie, Michigan. Locks from the left are: MacArthur, New second lock under construction, Davis and Sabin. On the right is the Hydro-Electric Power Plant and the rapids of the St. Mary's River. In the background is the International Highway Bridge from Sault Ste. Marie, Michigan to Sault Ste. Marie, Ontario, Canada and the International Railway Bridge. Compensating gates can be seen in the upper right of the photo at the rapids section of the river. Photo was taken Summer, 1962. battled National Steel's ERNEST T. WEIR and GEORGE M. HUMPHREY in the mid-1950's. Columbia Transportation's EDMUND FITZGERALD and Bethlehem's ARTHUR B. HOMER held the record in the early 1960's. The next major construction project was the Poe Lock opening in 1968, measuring 1,200 feet x 110 feet with 32 foot depth. Shortly thereafter in 1972, the first 1,000-foot vessel STEWART J. CORT became the largest vessel on the lakes. Today there are over a dozen 1,000-foot vessels transiting the Soo Locks. With the large number of 1,000-foot vessels and well as other vessels lengthened during their careers, the need for another large lock has been debated in Congress. Even though there has been a decline in the number of Great Lakes vessels, the majority of US-flag vessels require the Poe-size lock. The new lock would replace the Davis and Sabin Locks. Negotiations continue between the Army Corps of Engineers and surrounding states/provinces to find the necessary funds.
