This bridge is the first example of a unique telescoping vertical lift bridge. Originally designed as a unique double-deck bridge, the upper highway deck was placed high enough to permit all boats to pass under. The lower railroad deck on the other hand would need to be raised for boats. The unique design suspended the railroad deck from telescoping vertical members, which can be raised up inside the vertical members in the main truss. In short, the railroad deck could be raised without any movement of the upper (highway) deck, preventing any disruption of highway traffic. Shortly after this bridge was built noted engineering firm Waddell and Harrington applied this patented design to a similar bridge in Portland, Oregon. The bridge in Oregon has the additional feature where after the railroad deck was lifted, the highway deck could also be lifted even further, to accomodate unusually tall boats.

The ASB Bridge has suffered a major detrimental alteration in that the highway deck has been removed. Not only does this make interpretation of this unusual design more difficult for visitors, it also resulted in removal of an immense amount of the bridge, considering the approach spans for the upper deck were much longer than the railroad deck.
