Towboat "Betty June Walker" (doc. # 248942) upbound in Portland Canal approaching lift span of Conrail (later L&I) Bridge The lift span was built in 1918, replacing an earlier swing span at this location. This was about the time that the canal was widened from 90 to 200 feet, the 600-foot lock was built and the pool above the dam was raised eight feet to 420 feet above sea level. The span is 260 feet long (horizontal clearance for boats is 242 feet) and weighs about 2.6 million pounds. In the lowered position, vertical clearance above the river (at pool stage) is 39 feet; when raised, the clearance is 70 feet. The weight of the span is supported by a total of 64 two and one-eighth inch steel cables which pass over sheaves at the tops of the towers and connect to two huge counterweights. Because the weight of the span is balanced by the counterweights, it can be raised and lowered by a relatively small electric motor inside an enclosure on top of the span. The towers and machinery of the lift span were designed by Waddell and Son, Inc., and there is a plaque on the span reading, "Waddell Vertical Lift Bridge, Waddell and Son, 1917". The bridge tender's building can be seen left of center in this photo. See "Engineering News-Record", Vol. 82, No. 21, pp. 1007-1011 (May 22, 1919) In distance at left (with water tank on top) is LG&E's Canal Substation. Electricity is no longer generated there, but at one time it generated electricity for the Louisville Railway Company At time of photo, railroad tracks next to canal extended a few hundred feet upriver from bridge, on present-day (2014) route of Riverwalk. In the more distant past, I think they ran all the way through downtown.
