Original Champlain Bridge deconstruction | Lowering of the suspended span: An amazing feat of engineering!
The lowering of the main span of the original Champlain Bridge in January was the result of nearly two years of detailed design, coordination and planning. With support from our suppliers in Europe, the United States and Ontario, teams from JCCBI and Nouvel Horizon Saint-Laurent (NHSL) performed each step in this continuous operation that lasted over 17 hours.
Although this type of work is carried out around the world, it has never been done on this scale in Canada and especially not in changing winter conditions and under multiple operational constraints. Teamwork and innovation both helped make this project a success.
See how our crews lowered a 2,200-tonne and 117.5-metre span in one piece and kept it perfectly balanced all the way down the 33-metre descent.
