- Design: St. Lawrence Bridge Co.; Engineers: Henri Vautelet, Maurice Fitzmaurice, Ralph Modjeski, Charles MacDonald, Charles N. Monsarrat, and C.C. Schneider; After the collapse of the 1st bridge the Canadian government took over the project and appointed a board of engineers which included Henri Vautelet, Maurice Fitzmurice, and Ralph Modjeski. However, by the time of the bridge's completion Ralph Modjeski was the only original board member still involved with the project. A new design was chosen for the bridge by the St. Lawrence Bridge Co. which involved building the two sides of the bridge then floating the center span into place and lifting it up from the river with the use of jacks. The first attempt to lift the center ended with its collapse on Sept. 11, 1916, due to a steel casting failure. A new span was quickly created and the bearings re-designed so that the 2nd attempt was successful and the bridge was completed in 1917. At 1800 ft the Quebec Bridge has the longest cantilever span in the world. For more information see: William D. Middleton, The Bridge at Quebec (Bloomington: Indiana Univ. Press, 2001)

- From the early 19th century on many plans had been proposed for building a bridge at this site, but it was not until the early 20th century that plans for a bridge began to be carried out. Many commissions and committees in both Pensylvania and New Jersey were formed and in 1918 the consulting engineers Waddell and Son were hired to examine the possibility of a Delware River crossing. In 1919 the states of Philadelphia and New Jersey worked together to create the Delaware River Bridge Joint Commission and they were given permission to build. The chief engineer for the bridge was Ralph Modjeski with Clement E. Chase as assistant engineer, Leon S. Moisseiff as the engineer of design, and Paul P. Cret as the architect. By 1921 a site for the bridge was chosen and construction began in January of 1922. The bridge opened on July 1, 1926 and is today known as the Benjamin Franklin Bridge.

- Notes:
- Due to the increasing weight and train traffic the Michigan Central RR Bridge was built to replace the Michigan Central Cantilever Bridge. Its construction was delayed by WWI, but it was completed in 1925 by Michigan Central's engineer H. Isben and still exists today. For more information see: Spanning Niagara: The International Bridges 1848-1962 (Seattle: Univ. of Washington Press, 1984).
