Spectators watch as the first of the new 520 bridge pontoons is squeezed through the Ballard Locks as it makes its way to Lake Washington on Saturday, August 11, 2012. The pontoon was constructed in Grays Harbor and moved with tugboats to Seattle. It is the first of 77 pontoons of different sizes that will be used to build the floating span across Lake Washington.
