Astoria–Megler Bridge

The Astoria–Megler Bridge is a steel cantilever through truss bridge in the Pacific Northwest region of the United States that spans the lower Columbia River. It carries a section of U.S. Route 101 from Astoria, Oregon, to Point Ellice near Megler, Washington. Opened in 1966, it is the longest continuous truss bridge in North America.

The bridge is 14 miles from the mouth of the river at the Pacific Ocean. The bridge is four miles in length, and was the final segment of U.S. Route 101 to be completed between Olympia, Washington, and Los Angeles, California.
