The Sauvie Island Bridge crosses the Multnomah Channel of the Willamette River near Portland, Oregon, United States. The steel truss bridge, which is 1,500 feet (460 m) long, was built in 1950. It is currently being replaced by a new bridge.
Old bridge
Opened on December 30 1950, the first bridge to Sauvie Island replaced the Sauvie Island Ferry. The $900,000 bridge was designed by the Oregon Department of Transportation and built by Gilpin Construction. Oregon transferred ownership to Multnomah County in 1951. Composed of three steel truss spans, it was a total of 1,198 feet long, with the main span measuring 200 feet in length. The approach spans were built of reinforced concrete girders. Green in color, the bridge was 41 feet wide and carried two lanes of traffic and had sidewalks on both sides. The main span, a Parker truss, sat 80 feet above the water line and handled an average of 3,800 vehicles per day.
New bridge
After cracks were found in the 1950 span in 2001, Multnomah County restricted weight and speed on the bridge. Early designs for a new bridge were submitted in July 2004, and groundbreaking was held on January 4 2006. The new $38 million span was designed by H2L2 Architecture with David Evans & Associates as the design engineers, and built by Max J. Kuney Company. Located at river mile three, the main span is 360 feet long and rests 80 feet above the water. The main span is of a tied-arch design constructed of steel, while the approach spans are a box-girder style using pre-stressed concrete. The bridge has two lanes of traffic with shoulders and sidewalks on both sides for a total width of 66 feet. The bridge was floated into place after it was constructed.
In March, 2006, then-city commissioner Sam Adams proposed reusing the Sauvie Island bridge span as a bicycle/pedestrian bridge over Interstate 405 in downtown Portland, as part of the Burnside/Couch Transportation and Urban Design Plan. A coalition of Portland community groups including the Pearl District Neighborhood Association and the Bicycle Transportation Alliance have supported the idea. Adams ultimately retracted the proposal.
The new bridge opened June 23, 2008, and the old bridge was demolished after it opened.
