Pontoons being towed from Shilshole Bay
A sunny Saturday evening in Seattle, Washington set the stage for the largest pontoons ever built in the state to be floated in through the Hiram M. Chittenden Locks. Photo taken Aug. 11, 2012.
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.
