Pivot Bridge capsized.
--Yesterday morning the pivot bridge across the Dock at 17th street capsized, one end going down to the water's edge. The bridge was about being completed preparatory to use, and while being turned on the pivot, to enable the painters to paint it, the gearing gave way, precipitating one and to the water, snapping off the cast iron pivot, and crushing the cog wheel.--We presume the gearing will be repaired as speedily as possible.
