On Saturday 4/19/14, Pontoon A, the western-most pontoon for the new floating bridge, will be towed from its current moorage location on the Eastside, near Medina. The pontoon will be secured to a large marine crane barge over the weekend and will be connected to its permanent anchors next week. This is a major milestone for the SR 520 program as this is the second pontoon to be placed on its permanent anchors. With Pontoon W, the eastern-most pontoon for the new floating bridge already in place, the new floating bridge is beginning to take shape.

Repairs on Pontoon U continue within the coffer cell on Lake Washington. These repairs will be completed later this spring.
Construction of the segmental bridge, or balanced cantilever, near Lake Washington's Medina shoreline is well underway for the south (eastbound) section of roadway.
Pontoons are currently being stored in the lake's west side staging area. Crews have also begun adding rock to some of the pontoons to prepare them for joining.
West Connection Bridge construction is underway on Lake Washington near Madison Park. Crews have completed pile driving activities and have begun to install girders for this new bridge. Check out the progress graphic for more information on current construction activities.
Construction activities and project barges completely block the east navigation channel. These obstructions alter use of the east navigational channel and SR 520 drawspan. Read more information for boaters and SR 520 drivers.
