The Alexandra Bridge, also known as the Interprovincial Bridge, connects the cities of Gatineau, Quebec and Ottawa, Ontario, Canada’s national capital. It allows more than 9,000 pedestrians and over 150,000 vehicles to cross the Ottawa River daily. The Alexandra Bridge, built in 1901, is a cantilever bridge, making it an easy target for corrosion of its steel structure. Now 100 years old, this bridge has undergone several repairs.

In 2013, Brisson Peinture won its first call for tenders in the civil engineering sector for the rehabilitation of a portion of the Alexandra Bridge. The repair work lasted one year, during which we had the opportunity to work with very competent project managers from the company Stellaire Construction, general contractor.

The services rendered consisted of repairing the steel structure by sandblasting and waterblasting the old paint that had accumulated over 120 years on the steel beams and gratings. The stripping work is considered to be rough work. However, in the case of surface preparation of bridge steel structures, attention to detail is required to prevent rust from re-establishing itself on exposed surfaces.
