Pont ferroviaire Pie-IX


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.

Project objectives

  • Integrate sustainable materials, including glass powder from crushed glass bottles in the concrete mixes used.
  • Assure the long-term viability of a strategic asset essential to the Port’s freight capacity
  • Increase the Port’s rail capacity
  • Support the growth of Lantic Inc. sugar company, which has a $200 million investment plan to increase its annual refining capacity by 80,000 tonnes
  • Achieve workforce savings and reinforce modal interconnection across the port site
  • Ensure the safety of rail operations at the site
  • Contribute to reducing environmental impact by promoting rail freight transport over road transport
