Ontario, Canada Has Some Odd 'Bridges', Too
There is the Burlington Canal Lift Bridge <http://historicbridges.org/bridges/browser/?bridgebrowser=ontario/burlingtoncanalliftbridge/>. Nothing too exciting.
Peterborough Lift Lock on the Trent-Severn Waterway. It is a Hydraulic type built in 1904 and upgraded in the1980s. Length 43 metres (141 ft); Width 10 metres (33 ft); Fall19.8 metres (65 ft 0 in)
Coordinates 44°18′27″N 78°18′03″W.
The lock has two identical bathtub-like ship caissons in which vessels ascend and descend. Both caissons are enclosed at each end by pivoting gates, and there are pivoting gates at the upper and lower reaches of the canal at the junctions with the caissons. The gates on the caissons fit into slots on the gates on the reaches, so that they open in unison.
Each caisson sits on a ram, the shafts for which are sunk into the ground, are filled with water, and are connected with a pipe that has a crossover control valve. The caissons are guided up and down on either side by rails affixed to concrete towers. See Wikipedia: <https://en.wikipedia.org/wiki/Peterborough_Lift_Lock>
Kirkfield Lift Lock, Trent-Severn Waterway. Operation-Hydraulic. First built 1907 and upgraded in 1969.
Length 42.4 m; Width 10.1 m; Fall 14.9 m. Coordinates 44.58973°N 78.98981°W. See Wikipedia: <https://en.wikipedia.org/wiki/Kirkfield_Lift_Lock>
BUT OUR MOST UNUSUAL ONE is:
Big Chute Marine Railway
During WW1 the government decided improve the Trent-Severn river system. Located on south-east Georgian Bay there was a bloody great around which the river flowed. It had been decided to bypass the rick and they even built the beginnings of a canal and lock.
Then the war concluded.
So they ran railway lines over the rock. Boats were floated on to the carriages, which were submerged, and then inched up and the next boat was secured. Eventually the train was hauled over the rock and the baits released.
Big Chute Marine Railway is a boat lift at lock 44 of the Trent-Severn Waterway in Ontario. It works on an inclined plane to carry boats in individual cradles over a rock of about 60 feet (18 m). See Wikipedia: <https://en.wikipedia.org/wiki/Big_Chute_Marine_Railway>.
