New 520 pontoon arrives

SEATTLE -- The latest 520 bridge pontoon is expected to come through the Ballard Locks on its way to Lake Washington, according to a WSDOT press release.

Pontoon "A" will arrive from Grays Harbor Friday afternoon or evening. WSDOT reports it's the second of two pontoons that will form the ends of the new floating bridge.

Later this month crews will begin work on repairing cracks in the walls of four of the Cycle 1 pontoons built in Aberdeen.

According to WSDOT, one of the pontoons will be moved to a dry dock in Portland for repairs and another to a dry dock on Harbor Island in Seattle. The remaining two pontoons will be repaired on Lake Washington.
