Demolition of overpasses: explanations
In 2010, Jacques Cartier and Champlain Bridges Incorporated (JCCBI) responsible for the maintenance of the federal portion of Highway 15, decided to rebuilt three overpasses (on and beside A15) because they had reached the end of their service life and could not be further repaired. It was determined the work needed to go ahead to address immediate safety concerns. The reconstruction of those overpasses was done from 2012 to 2015.
Signature on the Saint Lawrence (SSL) was selected in April 2015 when the overpass reconstruction was very advanced and the final design of the new Champlain Bridge corridor was not known.
Once the design work started, it became apparent that the recently built structures could not be used because they did not meet the technical requirements nor the road geometry for the new Champlain Bridge corridor alignment.
In 2014, Infrastructure Canada which oversees SSL and JCCBI was aware of the possibility that the selected consortium might need to replace the structures in the near future dependent on the final design of the new Champlain Bridge corridor.
SSL wishes the timing had been different. The works in this sector will considerably improve fluidity in the corridor, and it will improve access to the new Champlain Bridge and to the downtown core with the construction of the new Gaétan Laberge urban boulevard.
