The Lewis and Clark Bridge is a cantilever bridge that spans the Columbia River between Longview, Washington, and Rainier, Oregon. At the time of completion, it had the longest cantilever span in the United States.[1]

The bridge was opened on March 29, 1930, as a privately owned bridge named the Longview Bridge. The $5.8 million cost (equivalent to $73 million in 2020 dollars) was recovered by tolls, $1.00 for cars and $.10 for pedestrians (equivalent to $12.53 for cars and $1.25 for pedestrians in 2020 dollars). At the time it was the longest and highest cantilever bridge in the United States. The state of Washington purchased the bridge in 1947 and the tolls were removed in 1965 after the bridge was paid for. In 1980, the bridge was rededicated as the Lewis and Clark Bridge in honor of the Lewis and Clark Expedition. The deck was replaced in 2003–04 at a cost of $29.2 million.

The bridge is 8,288 ft (2.5 km) long with 210 ft (64 m) of vertical clearance. The main span is 1,200 ft (366 m) long and the top of the bridge is 340 ft (104 m) above the river. It was designed by Joseph Strauss, the engineer of the Golden Gate Bridge.

In 1982, the bridge was entered on the National Register of Historic Places, as the Longview Bridge.[3] A feasibility study commissioned by the Washington State Legislature in 1990 recommended the construction of a second bridge to handle future traffic volumes.[4]
