ABERDEEN, Wash. (AP) — The first concrete is being poured Friday at the casting basin in Aberdeen where pontoons will be built for the new Highway 520 floating bridge on Lake Washington.
KBKW reports that building the basin is the first step in the construction of big concrete pontoons that will be floated to Seattle and linked together on the lake to form the bridge.
