4th cycle of SR 520 pontoons completed in Aberdeen

SR 520 Bridge Replacement

Another six State Route 520 bridge pontoons began floating out of the Aberdeen casting basin late Tuesday night, April 15, marking completion of the fourth of six cycles of pontoons being built in Grays Harbor. “With the fourth cycle complete, we’ve reached another important milestone for a new SR 520 floating bridge,” said Julie Meredith, SR 520 program director for the Washington State Department of Transportation. “We’re now two-thirds of the way done with all pontoon construction. In the coming months, the public will start to see the new floating bridge take shape as we begin to align, join and anchor the pontoons together on Lake Washington.” The fourth cycle of pontoon construction included four longitudinal pontoons and two supplemental stability pontoons. The 360-foot-long longitudinal pontoons will form the backbone of the new bridge, while the smaller, supplemental pontoons provide additional stability and flotation. Crews lifted three 50-ton gate sections last night to clear the way for the pontoons to float into Grays Harbor. The first pontoon exited the casting basin around 10:30 p.m., with the final pontoon expected out around 3 a.m. today, April 16. The new pontoons will be inspected at the Port of Grays Harbor and will then be temporarily moored. They’ll later be towed to Lake Washington for construction of the new SR 520 floating bridge. Full pontoon tracking details are posted online.
