Ottawa LTR

Ottawa, Canada

The new Light Rail Transit alignment runs in an underground scheme along 2,533 meters and three stations are allocated on it, Lyon (West), Parliament (East) and Rideau. Being a concession contract the scope of it is not only the design and construction of the infrastructure but also the maintenance for the next 30 years of the 12,5 km Confederation line.

Sequential excavation method SEM has been the solution for the mined portion. Three Roadheaders sandvik MT-720 were allocated to excavate the overall scheme since the ground is basically sound limestone.
