Open since 1962, the Champlain Bridge in Montreal is one of the city’s main road links and Canada’s busiest bridge, with an average of 136,000 crossings per day. Due to the extreme climate conditions in Montreal, as well as the use of road salt on the pavement, the bridge is suffering a progressive deterioration that different maintenance and repair plans have not been able to stop. Thus, the Canadian government decided to build another bridge as a replacement.
FUTURE OF CHAMPLAIN
Since 2015, the Signature on the Saint Lawrence Group, formed by SNC-Lavalin, ACS, and HOCHTIEF, is working on the construction of the New Champlain Bridge, located in parallel and a few yards away from the current bridge, which is still open to traffic. The new bridge will feature a spectacular 558 feet tall main pylon, which is being built with the support of a Linden Comansa 21LC550 crane.
The crane arrived to the jobsite in early September 2017 and was erected on the deck of the bridge with a height under hook of 222.4 feet. When the work of the crane ends, the crane will be 591 feet tall from the base of the pylon, 403 feet from the deck of the bridge. Montreal’s 21LC550 has maximum load capacity of 55,120 pounds to lift large precast concrete structures and heavy formwork panel. Another version of this crane is available with maximum load of 44,090 pounds.
The works at the New Champlain Bridge are expected to finish by December 2018.
