The original bridge was opened November 10, 1923, and was the first bridge to reach the island. George Lightfoot, known as the father of the other bridge on Mercer Island, the Lacey V. Murrow Memorial Bridge, had the charge of opening the bridge for boats. In 1940, it was demolished and replaced. Currently, two parallel bridges carry I-90 traffic at this location. A steel box girder bridge, built in 1981, carries westbound I-90 traffic. Another steel box girder bridge, built in 1988, carries eastbound I-90 traffic.
