Interior pontoon formwork
Tied-off for safety, crews set up wooden formwork that will be used to create the cast-in-place concrete that connects the internal panels. These internal cells enhance the durability and floatation of the pontoons.
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.)
