Macdonald-Cartier Bridge

It links King Edward Avenue and Sussex Drive in Ottawa with Autoroute 5 in Quebec.

It is owned and maintained by Public Works and Government Services Canada.

Immediately after the bridge on the Gatineau side, the road becomes part of the Autoroute where cyclists and pedestrians are prohibited.

The Ottawa side was to connect with Vanier Parkway, and some piers where it would cross the Rideau River remain[1] from the Canadian Pacific Railway's Sussex Street Subdivision, but this was cancelled because the route would have taken much of New Edinburgh Park.

[2] Construction is now underway to realign the entrance ramps on the Ontario side, removing any possibility of further extensions.
