Manhattan Murders Lead to Miranda Rights

The Evergreen Point Floating Bridge opened on August 28, 1963, spanning 7,578 feet across Lake Washington to connect Seattle and Medina on the Eastside. The bridge used concrete pontoons anchored to the lake bottom because the water was too deep for conventional piers, reaching 200 feet in places. It was the longest floating bridge in the world upon completion and carried State Route 520. The original bridge served for over 50 years before being replaced by a wider span in 2016, which reclaimed the record at 7,710 feet. The floating bridge concept, pioneered in Washington state, proved that deep freshwater lakes could be crossed without the massive expense of deep-water foundations.
