The Québec Bridge and the Pierre-Laporte Bridge were both major technological achievements. The former is still the longest cantilever bridge in the world, while the latter is the suspension bridge with the longest main span in Canada. Comparing the two public works also shows how techniques had evolved in just 50 years.

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.

Two bridges, two eras
