About the bridges

The ownership and custody of the five interprovincial crossings in the NCR is divided between Public Service and Procurement Canada (PSPC) and the National Capital Commission (NCC). PSPC owns and operates the Alexandra Bridge, the Chaudière Crossing and the Macdonald-Cartier Bridge, while the NCC is responsible for the Portage Bridge and Champlain Bridge.

The interprovincial crossings are vital links between Ottawa and Gatineau. In 2017, the five interprovincial crossings carried close to 150,000 vehicles and 9,000 pedestrians and cyclists on a daily basis.

Transportation studies conducted over the last 10 years have consistently shown that the existing crossings and connecting roadways are at full capacity during morning and evening peak hours.

Budget 2019 updates

Budget 2019 announced $80.4 million over 10 years to rehabilitate and maintain the Chaudière Crossing, the Alexandra Bridge and the Macdonald-Cartier Bridge. Over the longer term, Budget 2019 also made a commitment to replace the Alexandra Bridge as it is now more than 100 years old and nearing the end of its lifecycle.

Interprovincial crossings in the NCR are the responsibility of the Government of Canada. As the NCR population continues to grow, there is an acute need to increase bridge capacity in the region. That’s why Budget 2019 made the commitment to refresh existing studies for an additional NCR crossing. The NCC has awarded a contract to WSP Canada Group Limited to carry out this work.

Budget 2019 also committed to developing a long-term, integrated interprovincial crossing plan, led by the NCC with both provincial governments and the cities of Gatineau and Ottawa. Over the long-term, this plan will take into account all means of transportation, including Light Rail, public transit, vehicles, cyclists and pedestrian requirements.

In the interim, both PSPC and the NCC will keep working together to ensure bridges remain safe for commuters. Both organizations along with their partners are also developing new and innovative ways to minimize the impact of construction on commuters. This includes appropriately coordinating bridge projects and using barges, when possible, to complete work.

Earlier this summer, the NCC accelerated the Portage cyclist barrier project, while PSPC delayed the start of the Alexandra Bridge steel replacement project, to avoid having closures on both bridges. Additionally, the Alexandra Bridge steel replacement project will be completed using barges, which minimizes the required lane closures to complete the project and allow traffic to continue without disruption.
