The Longest Trusses in America

The longest truss bridge in America, and second-longest in the world, is the Astoria-Megler Bridge, which held the world record from 1966-1991. The Astoria–Megler Bridge is a steel cantilever through truss bridge that spans the Columbia River between Astoria, Oregon and Point Ellice near Megler, Washington, in the United States. Located 14 miles (23 km) from the mouth of the river, the bridge is 4.1 miles (6.6 km) long and was the last completed segment of U.S. Route 101 between Olympia, Washington, and Los Angeles, California.
