Petro-Canada unveiled plans to construct a 1,162 m-long 3.05 m-diameter tunnel under Marien Avenue linking the storage area of its Montreal refinery south of Sherbrooke Street with its facilities in the Port of Montreal. Four petroleum product pipelines will be installed in the tunnel which will replace existing pipelines currently situated beneath 2nd and 3rd Avenues. Quebec-based BFC Foundation has been hired as project contractors to excavate the tunnel at a depth comprised between 11.5 and 27.5 metres, using a hard rock TBM. The tunnel will be lined with concrete to reduce the risk of water infiltration. The cost of the proposed project is estimated at over $27 million. Visit www.petro-canada.ca 07/02.
