Southwest Calgary's Flanders Avenue interchange will open Monday, after more than a year of construction and traffic headaches.

A few more finishing touches will be completed this weekend, said Chris Elkey, spokesperson for the Canada Lands Company, which is overseeing the redevelopment of the former Currie Barracks.

"We hope to see traffic on there Sunday. What we've committed to is that it is open, fully functional, before the rush hour on Monday morning."

The project, which links into Crowchild Trail, incorporates three roundabouts — also known as traffic circles — into its design.

The priority was to improve connections for vehicles, transit, pedestrians and cyclists, and with limited space to work with, Elkey said they had to get creative.

"Unlike new interchanges out in the suburban areas where you have a lot more land to deal with, and that allows you to do different designs, we had less land which really necessitated a more thoughtful approach."

Construction of the new overpass has been underway since September, 2015.

The city and Canada Land Corporation agreed the company would build the $35-million overpass, and be reimbursed later as part of its revised, higher-density plan for Currie Barracks.
