Gov. Chris Gregoire and Washington Transportation Secretary Paula Hammond will visit Grays Harbor in two weeks to join the community in a groundbreaking celebration for the SR 520 pontoon construction project. The event is scheduled at 11 a.m. Saturday, Feb. 12, at the former Aberdeen Log Yard. Construction is expected to begin as soon as mid-February. The first order of work is to build a casting basin on the 55-acre property that will allow workers to construct 33 concrete pontoons for the SR 520 floating bridge. The pontoons will be available for emergency replacement of the floating bridge or stored until needed to form the backbone of a new SR 520 floating bridge scheduled to open by the end of 2014.
