Third Crossing - About Phase 4
ABOUT THE BRIDGE
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.
