In 1953, Oregon began construction of a highway bridge just east of the ferry landings to carry what became Interstate 5. The four-lane, north-south aligned bridge was finished in 1954 and opened to traffic in July, with the ferry ending service at that time. The state named the bridge Boone Bridge in honor of the Boone family. At the time there was a bronze marker in one of the bridge's piers to commemorate the name, but it was removed when the bridge was later widened.
