This bridge is significant as one of the group of historic bridges on Fort Point Channel. It is a pony truss Strauss trunnion bascule bridge with overhead counterweight. The bridge no longer operates for boats and the weight portion of the counterweight has been removed, although the framework remains.

The bridge tender building is next to the bridge and has been adaptively reused as a museum. Like the nearby Northern Avenue Bridge once had, this bridge's bridgetender building is a large, sprawling building which is in stark contrast to the tall and narrow bridgetender buildings familiar to the Chicago movable bridge collection.

The bridge was being rehabbed during the visit, so photography is limited. Photos of the bridge from Historic American Engineering Record, showing the bridge before counterweight removal and also the builder plaque are shown below.
