Interior wall setting at Satsop SR 520 test pontoon site
A crane lowers an interior wall into the test pontoon at the Advanced Construction Methods and Engineering site in Satsop. WSDOT’s work at Satsop is improving the way pontoons are constructed in preparation for the SR 520 project, which replaces that floating bridge on 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.
