Piedmont & Northern Steel Bridge in Mount Holly, North Carolina

I shot these photos of this interesting little bridge in Mount Holly, NC. The bridge is located near the front entrance of the Clariant Chemical Plant on South Alexandria Street. I can't tell if it was built to expand the number of tracks and never did, or had the tracks but the bridge sections were removed. Its in rough shape but still used by the CSX to service Clariant. This bridge is NCDOT New Piedmont & Northern trackage.
