Rehabilitation of the Pie-IX railway bridge
Spanning Pie-IX Blvd. north of the Port Road, the Pie-IX railway bridge is a key infrastructure at the core of the Port of Montreal’s rail network. The aim of the project is to ensure the long-term viability of the rail link, improve supply chain fluidity, increase rail capacity and optimize the flow of goods on the Port’s rail network.
Overview
Currently comprising three rail tracks, the structure is under heavy strain to accommodate growing rail transport needs, and requires major work on its foundations and decks. With a budget of $42.41 million, this project will restore the aging infrastructure, add a fourth rail track to the structure to create a 200-metre-long rail link over the bridge, and build three rail storage lanes for the Lantic sugar refinery northeast of the overpass. These three storage lanes will enable Lantic to increase its sugar-car storage capacity and boost production to meet demand from companies in Quebec and Ontario.
