Vertical-lift bridge
Generally speaking, they cost less to build for longer moveable spans.[1] The counterweights in a vertical lift are only required to be equal to the weight of the deck, whereas bascule bridge counterweights must weigh several times as much as the span being lifted.As a result, heavier materials can be used in the deck, and so this type of bridge is especially suited for heavy railroad use.The biggest disadvantage to the vertical-lift bridge (in comparison with many other designs) is the height restriction for vessels passing under it, due to the deck remaining suspended above the passageway.An example of this kind was built in Portland, Oregon, United States in 1912.
