the bridge has undergone extensive repairs and modifications. most notably, the top chord has had plates of steel welded to the top of the column. numerous rods and bars have been welded onto many of the vertical and diagonal members as well. a couple of added bars of steel run lengthwise through the middle of the truss. these modifications have affected the historic integrity of the bridge, but have no doubt helped keep it standing over 130 years. the original lattice guardrails remain on the sidewalk, albeit with a metal pole welded above them.
