Description of Improvements

The proposed solution for Duportail Street involves constructing roundabouts at the intersection of Duportail Street and Kennedy Road and Duportail and Vintner Square Driveway Entrance. Additionally, a median will be built starting at Keene Road and extending to Queensgate Drive, creating a physical barrier to better manage turning movements.
