The Quebec Bridge was 20 years in the making, from the found­ ing of the Quebec Bridge Company in 1887 to the bridge’s col­ lapse in 1907. Ethical Issues from the Tacoma Narrows Bridge Collapse . Efforts to promote ethical practice continue. Abstract: In the late 19th century, the transportation needs of Quebec led to proposals for bridging the St. Lawrence River. Woven from transcripts of the inquiry into the collapse, the report of the commissioners, and other sources including the coroner's inquest, On Cold Iron plays out like a fast-paced thriller. This course will examine the ethical issues that arose from the 1940 collapse of the Tacoma Narrows Bridge in Washington State. The bridge project was … The Quebec Bridge was the longest cantilever structure attempted until that time. The engineer that knew the problem only sent letters to the lead engineer and waited to go to talk to him. It was constructed to cross the Tacoma Narrows, part of Puget Sound, between the city of Tacoma and the Kitsap Peninsula. The University of Houston's College of Engineering presents this series about the machines that make our civilization run, and the people whose ingenuity created them.

A study on bridge failures carried out by the author concluded that most failures occur during construction or erection. In addition to the professional societies and chartering organizations efforts with their members, the Canadian Iron Ring and American Order of the Engineer trace their roots to the 1907 Quebec Bridge collapse. The Quebec Bridge was to be one of the engineering wonders of the world. Quebec Bridge collapse of 1907: • Bridge constructed over the St. Lawrence River (Levis to Quebec City) collapsed in 1907 • Several engineers worked on calculations at different times • Later engineers relied on calculations of prior engineers • Some engineers had no experience with this type of bridge The bridge is immense, not only in length and weight but in width. While a functional bridge may only have a few vehicles on it when it collapses, it takes hundreds of workers to build a bridge -- all of whom may be in dangerous positions in case of collapse. Ideas over building a bridge that connected the north part of the St. Lawrence River to the south part were popular in the mid to late 1800’s to allow ease of transport. Historically, the most infamous bridge failures include the Ashtabula bridge (Ohio, 1876), Tay Bridge (Dundee, Scotland, 1879), Quebec Bridge (St. Lawrence River, 1905), and Tacoma Narrows Bridge (Tacoma, Washington, 1940), which achieved notoriety because the catastrophic collapse was captured on an amateur’s movie camera. Major engineering failures act as a catalyst for change in standards of practice and therefore create the opportunity for establishing better ethical practices for the profession. The American Society of Civil Engineers have been trying to make citizens and politicians see that increasing taxes to make much needed repairs on America’s crumbling infrastructure is worthwhile.
