Aberdeen workers are over the halfway point in the State Route 520 pontoon building project, shipping off the latest batch of pontoons Oct. 5.
The Aberdeen facility will be responsible for constructing 33 pontoons, and crews have constructed 18 pontoons since 2011. The remaining 44 pontoons are being built in Tacoma. Each pontoon is about 360 feet long, 75 feet wide and 30 feet tall.
A new floating bridge spanning Lake Washington between Seattle and Bellevue should open to traffic some time in late 2015 or early 2016
