The East Channel Bridge is a motorway bridge in the U.S. state of Washington, which carries Interstate 90 from Mercer Iceland over Lake Washington to Bellevue. It crosses here the East Channel, which separates Mercer Iceland from east coast of the lake.
The first bridge was opened on 10 November 1923 and was the first firm connection to the island. The only six -meter wide wooden trestle bridge was 366 m long and was equipped with a rotating bridge that could be opened for navigation. It was operated by George Lightfoot, who started later for the construction of the Lake Washington Floating Bridge. The bridge was demolished in 1940 and replaced by a new building made of steel.
The present bridge consists of two steel box girders. The one for the carriageway to the west was completed in 1981, that for the carriageway to the east in 1988.
