As this aerial view from 1968 shows, the two pylons and the 62-cm-diameter suspension cables of the Pierre-Laporte Bridge were well anchored. The many segments of these structures were made in a shop and then assembled on site. Two elevators make it easier to maintain the imposing architecture over time.

The Pierre-Laporte Bridge, a feat of Quebec engineering

As automobiles became widespread in the 1950s and 1960s, the Quebec Bridge reached capacity. In June 1966, construction began on a second road link between Québec City and Lévis, 200 metres from the Quebec Bridge. It would connect several highways. Originally intended to be called the Frontenac Bridge, it was renamed before its inauguration in November 1970 as a tribute to Pierre Laporte, a minister in the Bourassa Administration who died during the October Crisis. It is considered the longest main span on a suspension bridge in Canada. Today, 120,000 vehicles cross it every day.
