Bridge Documentation

This bridge has an unusual design and history that makes it difficult to describe and to date. In 1887, a pin-connected railroad deck truss bridge was built near the current bridge's location. In 1922-1923, the trusses from this bridge were moved slightly to the current location to accommodate a new railroad line alignment. At this time, a third truss line with riveted connections was added in between the two 1887 truss lines. Because original 1887 truss lines remain a part of this bridge, HistoricBridges.org is retaining the 1887 date as the construction date for the bridge. However, much of this bridge material does date to 1922-1923. Additional rehabilitation work occurred in 1955. In 1999, the bridge deck was converted for pedestrian use.
