SR 520 Pontoon Construction in Aberdeen
The $367.3 million SR 520 Pontoon Construction Project includes designing and building a new pontoon construction facility, and constructing 33 new pontoons for the SR 520 Bridge. The existing bridge across Lake Washington in Seattle is vulnerable to windstorms, and is in need of replacement.
