Construction started on what was the largest floating bridge of its time on January 1, 1939. It was the first floating bridge to be built with reinforced concrete. Then known as the Lake Washington Floating Bridge and renamed the Lacey V. Murrow Bridge in 1967, it took U.S. 10, (now I-90,) from Seattle, through Mercer Island and on to Bellevue.
