Notes
Parsons Transportation Group was responsible for designing the longest main span bridge in Canada. The bridge, originally called the New Quebec Bridge, with a main span of 667.5 m (2,190 ft) and side spans of 186.5 m (612 ft) each for a total length of 1041 m (3,414 ft) between anchorages, crosses the Saint Lawrence River 198 m (650 ft) upstream from the famous old Quebec Cantilever Bridge and 8.1 km (5 mi.) southwest of historic Quebec City. The six-lane bridge, with a capacity of 90,000 vehicles per day, is the keystone of the Quebec regional highway network. It was constructed for the Department of Roads of the Government of the Province of Quebec with Parsons Transportation Group, in a joint venture, performing the construction supervision. Subsequently, in 1980, Parsons completed an in- depth condition inspection of the entire structure including the cable system in accordance with the Maintenance Manual that had been developed by Parsons about 10 years earlier. In 1993, Parsons conducted a preliminary aerodynamic study to evaluate the feasibility of adding a seventh reversible traffic lane on the bridge by converting the median barrier and shoulders.
Excerpt from Wikipedia
The Pierre Laporte Bridge (French: Pont Pierre-Laporte) is the longest main span suspension bridge in Canada. It crosses the Saint Lawrence River approximately 200 metres (660 ft) west (upstream) of the Quebec Bridge between Quebec City and Lévis. It spans 1,041 metres (3,415 ft).
It was originally named the New Quebec Bridge (Nouveau pont de Québec) and was supposed to be called Pont Frontenac (Frontenac Bridge) until it was renamed in honour of Quebec Vice-Premier Pierre Laporte, who was kidnapped and murdered during the October Crisis of 1970 as construction of the bridge was nearing completion. The bridge was constructed for the Province of Quebec, Department of Roads in a joint venture with the private firm of Parsons Transportation Group.
It carries Autoroute 73 northbound from Autoroute 20, the Trans-Canada Highway, to Quebec City and Autoroute 40 and also northwards towards Saguenay.
