A busy casting basin in Aberdeen as pontoon construction continues

Along the shores of Grays Harbor, the casting basin in Aberdeen is busy with construction workers building the third cycle of pontoons. Once complete, these pontoons will make the journey to Lake Washington where they will form the foundation of the new SR 520 floating bridge. Photo courtesy of Soundview Aerial Photography.

 

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.)
