Man of steel
A skilled ironworker helps assemble the inner steel rebar of a 360-foot-long longitudinal pontoon. Once complete, this single pontoon will weigh approximately 22 million pounds, making it heavier than the Eiffel Tower. Photo taken June 20, 2013.
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.)
