Steel Bridge in Portland, OR

[/caption] Portland’s Steel Bridge was opened in 1912 but its precursor was built in 1888. This bridge is the only double-deck vertical lift bridge of its type in the world and it’s one of the most multimodal in the world. It has three steel double-deck truss spans and two fixed side spans. The lower deck of the lift span was built for trains and may be lifted independently, telescoping into trusses of the upper deck that was built for street railways, pedestrians, automobiles and horse-powered vehicles. Eventually, the light rail train travels over the upper deck and pedestrians and the Union Pacific Railroad use the lower deck. However, both decks may be lifted together. This makes it one of the most amazing and spectacular bridges in the world. An it’s hard to imagine that it was built in 1912. Its main span length is 211 feet and the center height above water is 72 feet. The Steel Bridge is what most people use to cross the Willamette river when they are jogging, walking or bicycling around the city. There are also several Osprey or Hawks that can be seen resting on the tops of the bridge. This photo was taken from the east side of the river with parts of downtown Portland in the picture.
