New Champlain Bridge Corridor Project

  • One of the largest infrastructure projects in North America, due for completion in 2019.
  • Design driven to be technically sound with a high-quality architecturally pleasing solution.
  • New approach to Canadian public-private project (PPP) procurement of bridges.

The Champlain Bridge Corridor Project highlights Arup's use of global expertise to bring an innovative approach to the procurement of a multi-billion dollar infrastructure project in Canada. By providing timely, comprehensive technical and procurement advice, we have helped the Government of Canada to meet all project deadlines and thus realise an incredibly aggressive schedule.

Since 2012, Arup has been providing expert technical advice to the Government of Canada to facilitate the replacement of the 3.4km-long Champlain Bridge over the St Lawrence River and Seaway and 4km of congested urban highway. It is one of the busiest corridors in Canada and hence is vital to both the local and national economy.

Led by Arup’s local office in Montreal, our global team delivered a technically viable, affordable solution for inclusion in the 2013 business case which established the project costs, and the best means of procurement. When the condition of the existing bridge deteriorated in the fall 2013, Arup accepted the challenge of developing the design and technical requirement for this complex $4.239bn (CDN) PPP project so that the RFQ and RFP could be released within nine months.

The challenge was compounded by the objective to deliver a high quality architectural solution, whilst achieving a bridge with a 125-year design life. Arup led a team of international and local architects and specialists to create a unique signature bridge design, sensitive to the needs of Montreal and with the appeal to become a new icon on the St. Lawrence River for the city of Montreal and Canada as a whole.

The curved alignment and sculptural piers create an instantly recognisable shore-to-shore design with the elegant main tower and its harp of cables adding a unique accent to the bridge. The design accommodates future public transport plans by retaining the flexibility to run buses or a light rail train on a central transit corridor.
