The first recorded proposal to span the Columbia River at Astoria, by E.M. Elliott and Associates of Chicago.
The bridge at Longview, Washington was completed. The design of that span was done by the designer of the Golden Gate Bridge in San Francisco, California, Joseph Strauss.
Completion of the original Oregon Coast Highway.
The Port of Astoria formed a partnership with the Oregon State Highway Department, the Washington Toll Bridge Authority, and Pacific County, Washington, to assess the feasibility for building a joint bridge.

The legislatures of both states agreed to fund the project. Governor Mark O. Hatfield signed Oregon House Bill 1457 authorizing $24 million in Bonds to pay for the construction of the bridge.

This was the ceremonial groundbreaking, as the actual construction began later that year. The governor was assisted by Miss Oregon Estrellita Schid and Miss Washington Sandra Lee Marth
