Aerial Lift Bridge: Close-up of the Aerial Bridge lift span, Duluth, Minnesota

View of the lift span taken from the southeast corner of the U.S. Army Corps of Engineers building (1906). The canal’s piers have walkways, and there are benches for visitors to linger to watch the ships enter and exit the harbor. The Aerial Lift Bridge is the largest tourist attraction in the state of Minnesota. The enclosed portion on the lift span is the operator’s house or the power house of the bridge. On one side of the operator is Lake Superior and the other side is Superior Bay and the Duluth Harbor Basin. Leonard P. Green was the bridge operator for 36 years (died September 16, 1944). He was supervisor when the Aerial bridge was altered to become the lift bridge. In 1932, Mr. Green’s seven operators worked in eight-hour shifts, two operators to a shift.
