Four pontoons to leave Aberdeen in the next week

ABERDEEN – Two new State Route 520 bridge pontoons will leave Aberdeen for Seattle this weekend, while another two pontoons will follow next week.

Currently, eight pontoons are located in the Grays Harbor area: two pontoons completed in Cycle 2 – longitudinal pontoons Q and R – and six pontoons completed in Cycle 3 – longitudinal pontoons M, N, O and P and supplemental stability pontoons BSW and BSE.

The Cycle 2 pontoons are currently at a moorage site in Grays Harbor, while the Cycle 3 pontoons are at the Port of Grays Harbor. Pontoons BSW and BSE will be towed this weekend, and pontoons Q and R will leave next week. Pontoons M, N, O and P will move to the Grays Harbor storage site.

Prior to ocean towing, all pontoons are inspected by pontoon contractor Kiewit-General Joint Venture, the Washington State Department of Transportation, floating bridge contractor Kiewit/General/Manson, A Joint Venture, and the floating bridge contractor’s insurance agent. Additional inspections will take place on Lake Washington after the pontoons arrive in Seattle.

Pontoon tracking details are posted online.

Construction is underway on the next cycle of six pontoons in Aberdeen. An additional cycle of eight pontoons is due this winter from Tacoma. A new staging area is under construction on the west end of the SR 520 floating bridge on Lake Washington.
