For many years, there has been discussion about joining the east and west ends of the city with a third route – a bridge over the Cataraqui River.

The two existing routes from east-to-west are Highway 401 and the Lasalle Causeway – neither is owned by the City.

In 2013, an environmental assessment was finished to determine:

  • The need for a third crossing
  • The impacts a third crossing could have on the natural, social and economic environments
  • The best location for the bridge
  • The bridge design concept (Arch with V-Piers)

Frequently asked questions

The most commonly asked questions about the Third Crossing will be posted to the FAQ page over time.

Benefits of a third crossing

The environmental assessment found benefits of a bridge would be to:

  • Increase travel time savings while reducing greenhouse gas emissions
  • Decrease traffic congestion along the Lasalle Causeway
  • Provide additional access to the east end of the city for emergency vehicles and City services
  • Provide an alternative route during Lasalle Causeway closures
  • Provide an opportunity for active transportation with a multi-use trail
  • Accommodate future growth
  • Enhance the Rideau Canal


The environmental assessment studied a range of factors affecting location including: neighbourhoods, marine life, plants and wildlife, shorelines, noise, watercraft navigation, intersection with other transportation routes and more. 

Based on its findings, the best location for a bridge is a link between Gore Road and John Counter Boulevard.


There are four key phases of the project.

  • Phase I - The environmental assessment.
  • Phase II - The preliminary design phase – began in February 2016.
  • Phase III - Developing a business plan is the third phase and overlaps with phase II.
  • Phase IV - This plan will be developed if council directs staff to move forward with the project.


Construction costs for the proposed bridge are estimated at $120 million plus tax (2011 dollars) for a two-lane crossing with an accessible, multi-use trail for active transportation. 

Due to the significant capital costs associated with the Third Crossing, provincial and federal government grant funding has been identified as a major component of the anticipated funding for the overall project.

The cost estimate will be refined as the city progresses through the Third Crossing Action Plan.
