Île-d'Orléans Cable-Stayed Bridge

Preliminary design

  • Île-d’Orléans, Québec

    Île-d’Orléans, Québec

Creating an iconic structure on a heritage site

Built in 1935, the existing Île-d’Orléans bridge in the Quebec City area no longer meets today’s requirements. This prompted Quebec’s Ministry of Transportation (MTQ) to launch the construction of a new 2.1-kilometre (1.3-mile) cable-stayed bridge to the west of the current structure. The new bridge, which is slated for completion by the end of 2027, will feature two wider lanes of traffic, shoulders, and a multi-use lane for pedestrians and cyclists in each direction. The project also includes redeveloping the northern interchange and adding new green spaces.

At the head of the project’s joint venture, Groupement Origine Orléans, Stantec and EXP produced the preliminary design of the new bridge connecting Île-d’Orléans and the north shore of the St. Lawrence River. The design was created in collaboration with world-class partners and took into account sustainability requirements as well as the site’s geography and climate. We carried out an environmental impact assessment on behalf of the MTQ to ensure the project would be fully integrated into the environment while respecting the island’s unique heritage and landscape.

The bridge concept is inspired by the island’s maritime history and showcases the river and the natural landscape of the site. It also tailors the experience to users and promotes active modes of transportation across the river. In addition to providing unparalleled views of the island, Quebec City, and Montmorency Falls, the bridge will also be lit at night to feature the elegant cable-stayed structure.
