There are only a few covered bridges left in Canada. In Quebec, despite over 1,200 existing in the last century, today there are only 88 remaining.[1][2] In New Brunswick, 58 covered bridges have been identified.[3]
Canada's longest bridge is the Confederation Bridge in the Gulf of St. Lawrence with a total of 12,910 metres (8.02mi) between abutments, it's also the world's longest bridge over ice-covered water. More than 5,000 local workers helped with the project, which cost about $1 billion.[16][17]
The Quebec Bridge has been the longest cantilever bridge span in the world since 1917, measuring 549 metres (1,801ft) between its two piles.[H 12] It held the record of all-categories longest span in the world until the opening of the Ambassador Bridge. It’s the last bridge that broke such a record before suspension bridges hold the award by far.[18] It was designated a National Historic Sites of Canada in 1995.[H 12]
In 1929, the Ambassador Bridge between Canada and United States surpassed the Quebec Bridge with a 564 metres (1,850ft) main span and became the longest crossing in the world[19] until the inauguration of the George Washington Bridge in 1931 in New York City which almost doubled the range hitherto achieved.[20]
Studies have been carried out for crossing the Saguenay River near Tadoussac just before the confluence with the St. Lawrence River,[21] the latest project presented by the COWI A/S company includes the construction of a 1,145 metres (3,757ft) span suspension bridge with a 70 metres (230ft) clearance above the river.[22]
This table presents the structures with spans greater than 100 meters (non-exhaustive list).
↑ The Victoria Bridge has originally one railway track, it was modified into a truss bridge in 1901, in order to widen it and accommodate a second railway track, as well as a track for trams. Today it is a Railroad Bridge.[4]
↑ The length given only takes into account the main bridge, central span(s) and shore span(s), approach viaducts are not counted.
↑ The bridge's span has been given lengths that ranged from 800 to 825ft by various sources. This article takes the length stated by McCullough.[85]
↑ The covering of the towers was carried out in 1872, in 1884, the wooden towers were replaced with steel, finally all the wooden components were replaced with steel in 1888 and the deck was widened.[88] The bridge can then have very different appearances depending on the year.
