The middle piers for that bridge were removed but you can just barely see the base of a pier on the western side just below the surface of the water. The abutments are still there on either side and can be accessed by the pedestrian bridge that goes from Columbia, NJ to Portland, PA. The huge Lehigh Gap bridge suffered the same fate and only the abutments remain for that bridge as well. There are however a ton of smaller bridges along the main including the one sizable truss bridge over the Paulinskill just a stones throw away from the old Delaware River bridge site.
