Big progress on Cycle 3

In-basin construction of the Cycle 3 pontoons built in Aberdeen began in early May 2013. This photo, taken June 20, 2013, shows just some of the progress that's been made since then.

 

Construction crews are underway on the third cycle of SR 520 bridge pontoons in Aberdeen. In this cycle, crews will build six total pontoons:

 

• Four longitudinal pontoons (360 ft. x 75 ft. x 29 ft.)

• Two supplemental stability pontoons (98 ft. x 60 ft. x 28 ft.)
