Final concrete pour on SR 520 test pontoon
Work on the test pontoon at the SR 520 test pontoon site in Satsop wraps up April 16, 2010 during the final concrete pour. The work gives WSDOT a leg up on upcoming pontoon construction in Grays Harbor County, during which 33 new pontoons will be built in order 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.
