Welcome home to the first pontoon!
The first of the SR 520 floating bridge pontoons completed its journey around the Olympic Peninsula and through the Puget Sound on Aug. 11, 2012 and now floats in Lake Washington near Medina. Construction workers will build the new SR 520 roadway on top of this longitudinal pontoon.
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.
