The first pontoons finally float into Grays Harbor
It’s been almost 18 months since the groundbreaking of the SR 520 pontoon construction site in Aberdeen, and the first pontoons have finally been pulled out into Grays Harbor.
Aberdeen Mayor Bill Simpson was at the ground breaking in February of 2011, and at the launch last night said how gratifying it was to see the project in action.
Washington State Department of Transportation Secretary Paula Hammond said that it you can see all of the progress on the faces of the workers locally.
The pontoons were scheduled to float out months ago, but cracking and flaking was found after post-tensioning tests on the giant cement structures. Crews had to remove concrete and insert additional rebar to endure the pontoons were able to hold up to the massive weight of the SR 520 bridge.
Construction can now begin on the next five cycles with 27 more pontoons planned for construction in Aberdeen between now and 2014.
