"The Sauvie Island Bridge crosses the Multnomah Channel of the Willamette River near Portland, Oregon, United States. The original Parker truss bridge, built in 1950 with a 200-foot (61 m) main span, was replaced with a tied arch bridge with a 360-foot (110 m) span in 2008 due to cracks discovered in 2001."

"...this historic Parker truss bridge was completed in 1950 but will soon be relocated, and another bridge, which will arrive via barge on the Multnomah Channel, will replace it."

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 (365 m) long, with the main span measuring 200 feet (61 m) in length. The approach spans were built of reinforced concrete girders. Green in color, the bridge was 41 feet (12 m) wide and carried two lanes of traffic and had sidewalks on both sides. The main span, a Parker truss, sat 80 feet (24 m) above the water line and handled an average of 3,800 vehicles per day.[1]
