Papineau-Leblanc Bridge


Conception

Ingenuity, solidity and elegance are all words that apply to the Papineau-Leblanc Bridge. In silhouette, it suggests a twin-masted ship with its stays and cables running from the top of the towers to the deck of the bridge. These cables are, in fact, coated with polyethylene, to avoid corrosion. Suspended by stays, the steel decks contain six lanes paved with a new material: asphalt treated with natural rubber.

Measuring 425 metres in length and 27 metres in width, the structure had to respond to two distinct challenges: to avoid ice buildup at the Hydro-Québec dam 1,000 metres downstream and to facilitate pleasure boating on the Rivière des Prairies. The answer was to build the minimum number of piers possible, circular in shape, widely spaced and clad with a steel plate anchored to the concrete to protect against premature wear caused by the ice.

At the time of its inauguration, the 425-metre Papineau-Leblanc Bridge was the longest cable-stayed bridge in North America.
