Portland-Milwaukie Light Rail Bridge


A central piece of the Portland-Milwaukie Light Rail Project is a new bridge across the Willamette River. In Portland, this will be the first span built over the river since the addition of the Fremont Bridge in 1973. The Portland-Milwaukie Light Rail Bridge will be a multi-use transit bridge with a total length of 1,720 feet. It will be distinctive in the United States, carrying light rail trains, buses, cyclists and pedestrians and, in the future, streetcars. The bridge will not accommodate private vehicles, although the structure will be designed to allow emergency responders to drive on to it if necessary. This photo shows one of the two in-water towers in construction. After the two towers are built, creation of the bridge deck will begin using a balanced-cantilevered method whereby an equal section of the bridge deck is constructed on each side of the tower followed by installation of its cable supports.
