Bridge Documentation

This bridge was completed in 1912 and was designed by Waddell and Harrington, a firm that led the way in the development of the modern vertical lift bridge and was always a major proponent of that type of movable bridge. With a 1912 construction date, this is an early surviving example of a bridge by that firm. In 1925, the bridge deck was raised 16 feet to accommodate newly built railroad tracks nearby. Evidence of this project is most visible on the piers for the plate girder approach spans, where unusual little metal bents were added on top of the concrete piers.

This bridge continues to raise and lower as needed for the boats and trains it serves.

This bridge is right next to the historic Robert Street Bridge.
