New two-lane roundabout at Southdale Road West and Colonel Talbot Road fully opens on Monday, November 20

The intersection of Southdale Road West and Colonel Talbot Road will fully reopen as a two-lane roundabout on Monday, November 20, marking substantial completion of the Southdale and Colonel Talbot Roundabout Project, more than three weeks ahead of schedule. 

The City of London began reconstructing the intersection of Southdale Road West and Colonel Talbot Road earlier this spring, to improve traffic flow and address safety challenges in one of the fastest growing parts of the city. 

The intersection has been reconfigured as a two-lane roundabout with active transportation improvements, including separated bike paths and new pedestrian sidewalks and crossovers, to help improve comfort and safety for all road users and better accommodate existing and future travel demand.

There is a growing number of two-lane roundabouts in Ontario and across the country, as roundabouts are better for the environment and result in less severe types of collisions in comparison to signalized intersections.

Navigational signage and pavement markings are in place to guide drivers through the intersection.  Additional information on two-lane roundabouts, including quick tips and images, and the video below, can be found on the City of London website at
