Keel slab pour at Satsop pontoon test site
Quigg Brothers Construction crews pour concrete and use a pencil vibrator to remove air and consolidate the mix during the pour Jan. 22, 2010, at WSDOT's Advanced Construction Methods and Engineering site in Satsop, Wash. The test floating bridge pontoon provides WSDOT with new construction methods that can be used when constructing the new SR 520 floating bridge pontoons in Grays Harbor County. The new pontoons will be used to replace the SR 520 floating bridge across Lake Washington. The test pontoon section is 120 feet long, 38 feet wide and 28.5 feet tall, roughly one-sixth the size of the largest of the final pontoons WSDOT will build for a new SR 520 floating bridge. A new bridge is scheduled to open to traffic in 2014.
