From the Richmond Dispatch, 11/14/1860, p. 1, c. 7
The Pivot Bridge, which capsized on Monday last, will be repaired and put in working order with as little delay as possible. The accident occurred by attempting to turn the bridge on the pivot with too much weight on one end, before the balance wheel had been placed in position. When completed, it will be a handsome superstructure, and one of great convenience to vessels in the dock.
