SR 520 email update - April 18, 2014
Pontoon A moves into its final location on Lake Washington
On Saturday, April 19, Pontoon A, the western-most pontoon for the new floating bridge, will be towed from its current location on the east end of the lake, 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.
The pontoon will be located on the west side of the west navigation channel, reducing the channel width from 206 feet to 120 feet. The narrower channel will be marked by traditional red and green buoy channel markers. This new, temporary configuration will be in place until additional pontoons are joined with Pontoon A. This change does not affect the vertical clearance of 45 feet at the west navigation channel.
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.
