Construction was ultimately completed in September 1917 at a total cost of $23 million and the lives of 88 bridgeworkers. On 17 October, the first train crossed the bridge from Quebec to Lévis, and on 3 December 1917, the Quebec Bridge officially opened for rail traffic, after almost two decades of construction. Its centre span of 549 m (1800&nbsp;ft) remains the longest cantilevered bridge span in the world and is considered a major engineering feat. The Quebec Bridge was declared an [[Historic Civil Engineering Landmark|International Historic Civil Engineering Landmark]] in 1987 by the Canadian and American Society of Civil Engineers.
