- 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)
