Montreal Mayor Denis Coderre has announced a stretch of the Bonaventure Expressway will be replaced by an urban boulevard. Construction will begin in 2015.

Coderre said the expressway will remain open during construction. He said the province and city will work to minimize the impact on traffic flow.

The new version will feature green space and nine ground level lanes. It will have pedestrian corridors and connect to new cycling paths on William Street and Ottawa Street.

The project should be completed in 2017, in time for Montreal's 375th birthday, Coderre said.

It will be renamed Robert-Bourassa Boulevard.
