Barnsdale Road 416 Interchange Closer to Completion

Barnsdale Road 416 Interchange Closer to Completion  

 The Province of Ontario and the City of Ottawa signed a legal agreement allowing the Environmental Assessment to proceed benefitting the drivers of Barrhaven. 

NEPEAN — The Ontario government has reached a formal agreement with the City of Ottawa to proceed with an Environmental Assessment (EA) to facilitate a future Highway 416 interchange at Barnsdale Road in southern Barrhaven.

Lisa MacLeod, Minister of Heritage, Sport, Tourism and Culture Industries and MPP for Nepean, was joined by Councillor Jan Harder, Ward 3 Barrhaven, earlier today to provide an update.

“This is a major milestone in the efforts to establish a much needed 416 interchanges in Barrhaven,” said Lisa MacLeod, Minister of Heritage, Sport, Tourism, and Culture Industries and MPP for Nepean. “Barrhaven is one of the fastest-growing communities in Ontario, and an additional highway interchange will help to facilitate economic growth, alleviate congestion and reduce commute times for residents.”

The community of Barrhaven has seen some of the fastest growth in Ontario, with its population increasing from 40,000 in 2001 to 77,000 in 2012 – an increase of 85%. Today, Barrhaven’s population is over 90,000 and is projected to increase by almost 20,000 residents over the next ten years.

This new interchange at Barnsdale Road will play a key role in helping to alleviate traffic on the major north-south roads and divert more cars to the currently underused 416 highway.

Our government is proud to be able to support the City of Ottawa in making this important project a reality by undertaking the preliminary design EA work, which will be funded by the City of Ottawa. A contract for the EA and design work has been finalized and awarded to Morrison Hershfield Limited, which means the project is one step closer to getting environmental approval.

“On behalf of our government, I am thrilled to be partnering with the City of Ottawa to undertake the preliminary design EA work for the future Highway 416 interchange,” said Caroline Mulroney, Minister of Transportation. “This is critical work to help plan for the future needs of this fast-growing region”.

Our government will continue to work with the City of Ottawa to help ensure they can accommodate future growth and keep people moving now and for generations.

“Building the Barnsdale Interchange is a top priority for the residents and businesses of Barrhaven and the City of Ottawa. More direct access to Highway 416 will help support our rapid residential growth as well as the flurry of economic activity and the thousands of new jobs finding a home in Barrhaven,” said Councillor Jan Harder.



  • The 2013, City of Ottawa Transportation Master Plan Update included widening of Barnsdale Road from Highway 416 easterly to Prince of Wales Drive and their Road Network. The City of Ottawa 2031 Network Concept included a new interchange (not partial) at Highway 416/Barnsdale Road.
  • Two Public Information Centres (PICs) are planned later this year. They will allow interested stakeholders to learn more about the Study process and to discuss issues or concerns directly with members of the Project Team. More information can be found at:
