As part of the development application for Bedford West Sub Area 10, Harbourside completed a traffic impact study to quantify the transportation impacts of the proposed development. The study evaluated traffic operations at Highway 102 and Kearney Lake Road interchange currently controlled by two signalized intersections that are operated by the same traffic controller.

The study identified existing operational problems at the Kearney Lake Road interchange and projected that with background traffic growth alone, the southbound off-ramp will exceed capacity during both peak hours by 2031. The study concluded that improvements are required at Highway 102 and Kearney Lake Road interchange to accommodate background traffic growth and the full build-out of the Bedford West Sub Area 10 development. The study recommended that the two signalized intersections be converted to roundabouts to accommodate long-term growth at the interchange.
