- Historic_BR_Passaic.pdf quote "J. B. Strauss invented the pivoting counterweight linkage used at the Eighth Street bridge, and he applied for a patent in 1905, the same year the first bridge of this type was built in Cleveland. That year he also founded the Strauss Bascule and Concrete Bridge Company in Chicago to market his bridge designs. Strauss went on to become the most widely respected moveable-span bridge engineer of the pre-World War II era. Strauss reasoned that if, unlike the traditional trunnion bridge, which operates like a seesaw and moves in a vertical plane on a horizontal steel pivot, the entire weight of the counterweight could be concentrated at the end of the moveable leaf, it would then be possible to use a lighter counterweight. Such an arrangement also meant a shorter tail end to the leaf, thus saving on materials that the "counterweight could be made in such shape that no pit is required to receive it when the leaf is in the upright position'" . The patented linkage, or arms, ensures that the counterweight will always move in a series of parallel positions and thus maintain the position of the weight at the tail end of the leaf.".
- Historic_BR_Passaic.pdf quote "The thru truss rim-bearing swing span bridge on an ashlar substructure was erected in 1906 by the Owego Bridge Co. It is of riveted construction with the exception of the center tower, which has pinned top chords composed of stamped eye bars. The bridge has been altered. In 1985 the operating machinery and operator's house located above the roadway were removed. The flooring system was replaced, and additional section was bolted onto some verticals and diagonals. However, the changes do not preclude the individual eligibility of this structure for listing in the National Register of Historic Places under Criterion C as a representative example of a through truss rim-bearing span. All of the key visual elements of the bridge - the trusses by the Owego Bridge Company, the center pier, the wheels that run on a track making it a rim - bearing span, and the ashlar abutments retain integrity.".
