Floating in the first SR 520 bridge pontoon
Crews worked together closely on Aug. 11, 2012 to float in an 11,000 ton bridge pontoon from Shilshole Bay to Lake Washington.
Crews floated in the first longitudinal pontoon for the new SR 520 bridge through the Hiram M. Chittenden Locks on August 11, 2012. Arriving just after 6 p.m., the entire operation took around 45 minutes and was observed by hundreds of spectators enjoying the sunny Saturday in Seattle, Washington. This pontoon is the first of 77 that will make their way from their casting basins to Lake Washington during the next two years.
