English: Why preserve this big hunk of steel?
This steel structure looks like a bridge, but it is actually a dam. It is called the Emergency Swing Dam, since it was designed to swing out over the canal in an emergency and greatly slow the flow of water. Only nine emergency swing dams were constructed worldwide, and today, this is the only one remaining. Of the nine constructed, this is the only one ever put to the test under emergency conditions. The Emergency Swing Dam is an innovative engineering achievement designed and built by Canadians over 100 years ago, and is commemorated for its successful use during the accident in 1909. Parks Canada protects the dam and the canal to preserve our heritage for this and future generations.Français : Pourquoi préserver cette énorme structure d'acier?
Même si elle ressemble à un pont, cette structure d'acier est en réalité un barrage. Il s'agit plus précisément d'un barrage tournant de secours, car il a été compu pour pivoter en travers du canal en cas d'urgence afin de ralentir le débit d'eau Seulement neuf barrages tournants de secours ont été construits dans le mond; celui-ci est le seul à subsister, et le seul à avoir fonctionné en situation d'urgence. Le barrage tournant de secours est un réalisation technique innovatrice conçue et construite par des Canadiens il y a plus d'un siècle. On le commemore parce qu'il a été utilisé avec succès lors d'un accident survenu en 1909. Parcs Canada protége le barrage et le canal afin de préserver notre patrimoine pour les générations d'aujourd'hui et de demain. |
