The province is funding a new Barrhaven interchange along Highway 416 to meet the needs of booming subdivisions in the area — one of Ottawa’s few capital projects in the 2024-2025 Ontario budget.
Barrhaven has only one exit off the 416 at Fallowfield Road. A second exit at Bankfield Road further south predominantly serves Manotick.
Barnsdale is in the roughly 10-kilometre gap between the two, offering an easy connection with Greenbank Road.
Before I look this up, is this the same phenomenon related to extra highway 401 lanes in Toronto that didn’t actually relieve congestion?
Yup. Basically people start switching to use the thing that you invest in expanding. So traffic can’t be improved by adding more car infrastructure. You need to invest in other stuff like trains, streetcars, buses, etc. if you want to alleviate traffic
