Each girder is 190 feet long and weighs more than 15,000 pounds. It takes eight of them to make up one giant piece of hardware for the new State Route 520 floating bridge. It’s called a hinged transition span and it’s critical to the floating bridge. The span will allow the new floating bridge to move with Lake Washington and serves as a connection between the floating bridge and the fixed-column approach of the highway in Medina. It took about three days this week to complete the work shown here.
