A contemporary observer unimpressed with the new structure concluded If the machinery used to open and close the water way is fixed on the span, then the bridge is called span drive vertical lift bridge, whereas the bridge is termed as tower drive vertical lift bridge if machineries applied to lift and down the lift span is fixed on towers, in addition to many other variations of vertical lift bridges. Our engineers designed the rehabilitation of the structural, mechanical, hydraulic and electrical systems. The upper framework of the lifting span generally consists of two independent steel towers with sufficient stiffness to prevent encroaching on each other, with the span itself consisting of a steel Pratt type truss arrangement. He wrote, Vertical-lift bridge-The biggest disadvantage to the vertical-lift bridge (in comparison with many other designs) is the height restriction for vessels passing under it. It is called span drive vertical lift bridge if the machinery which is responsible for the up and down movement of the span is fixed on the span itself and it is called tower drive vertical lift bridge if that machinery is fixed on the towers. These bridges can be used for locations where long spans are required and are substantially stable ones. The original vertical lift bridge, built in 1930, is 2,169 ft. long with 14 deck-girder spans and three through-truss approach spans, two tower spans and a 209-ft. vertical lift main span.
