Where the Columbia River meets the Pacific, 4.1 miles of steel truss connects Oregon to Washington.
The Astoria-Megler Bridge, completed in 1966, is the longest continuous truss bridge in North America.
It spans the mouth of the river where Meriwether Lewis and William Clark stood on November 15, 1805, and looked at the Pacific after eighteen months of travel.

That is how it tends to go with the ones built to last: they become invisible through use.
