Historical Note

The Fremont Bridge in Portland, Oregon, which carries Interstate 405 and U.S. 30 traffic over the Willamette River, opened on November 15, 1973. With a main span length of 1,255 feet, it was the longest tied-arch bridge in the world until 2004. At the time, the March 1973 hoisting of the 900-foot, 6,000-ton center span, which was floated 1.7 miles up the Willamette on two barges from its assembly site at Swan Island, was the heaviest bridge lift ever completed. During the 50-hour lift, the span was raised 175 feet using 32 hydraulic jacks.

Content Description

The collection consists of fifty-six 35 mm color slides taken during construction of the Fremont Bridge in March 1973. The slides depict the bridge's main span being transported down the Willamette River by barge and lifted into place. The slides were taken for the Oregon Department of Transportation by an unidentified photographer. The collection also includes typescript descriptions of each slide. Researchers should note that the descriptions include incorrect dates for some images. Though the descriptions give a date of March 21, 1973, for slides showing the bridge span before it was lifted into place, the lift actually occurred several days earlier, on March 15-16.
