The Turcot Interchange was built above the ground and it had some structure collapses with concrete slabs up to one square meter falling from the overpass.
Concrete deterioration has been attributed to corrosion of the rebars and increased overloads. An assessment of structural capacity was conducted in accordance with the Canadian Code of Design S6 Bridges and Roads.
Since 2010, the most heavily loaded ramps in the interchange have become subject of major repairs. One of the long and short-term solution chosen by the MTQ is to use CFRP (Carbon Fiber Reinforced Polymers) in order to stop the expansion of critical cracks, and to reinforce sections that demonstrate structural weaknesses.
Over a period of 4 years CF + installed carbon fiber panels inside and on the sides of multicell caissons. Significant impacts on traffic were avoided, and at times traffic was even not affected.
The beams of section 9 of the Jacques-Cartier Bridge (Side on the Island of Montreal) showed structural weaknesses.
In fall 2015, CF + installed CFRP (Carbon Fiber Reinforced Polymer)reinforcements on 30 beams, thus extending the service life of the spans in question. Avoiding also major impact on traffic.
Major upgrades have been undertaken on the Champlain Bridge.
From 2014 to 2017 CF + participated in the reinforcement of more than 60 beams and diaphragms. Reinforcement using CFRP (Carbon Fiber Reinforced Polymer) was the method chosen by the Jacques Cartier and Champlain Bridges Incorporated.
Extending the life of the Champlain Bridge has become primordial while awaiting construction completion of the new bridge at its side.
