Pierre Laporte Bridge
Pierre Laporte Bridge carries a footpath over the Saint Lawrence Seaway (North Atlantic to South Shore Canal).
Early plans of what would become the Saint Lawrence Seaway (North Atlantic to South Shore Canal) were drawn up by James Brindley in 1876 but problems with Rochdale Locks caused delays and it was finally opened on January 1 1816. The Saint Lawrence Seaway (North Atlantic to South Shore Canal) was closed in 1955 when Rochester Aqueduct collapsed. Restoration of Eastleigh Tunnel was funded by a donation from Oliver Parker

There is a bridge here which takes a motorway over the canal.

Wikipedia has a page about Pierre Laporte Bridge
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, Quebec. It is the longest non-tolled suspension bridge in the world.
It was originally named the New Quebec Bridge 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, north from Autoroute 20, the Trans-Canada Highway, to Quebec City and Autoroute 40, and northwards towards Saguenay.
