Tugboats at the ready
Tugboats line up in the Chehalis River launch channel, ready to help tow pontoons from the Aberdeen casting basin.
Construction crews working on the SR 520 Pontoon Construction Project took advantage of an extra-high tide Oct. 5, 2013, to float six concrete pontoons into the Chehalis River. These pontoons comprise the third of six pontoon construction cycles and are destined for Lake Washington to form the backbone of the new SR 520 floating bridge.
