Land was reserved at the Highway 401/403/410 junction for a loop ramp from Highway 403 eastbound to Highway 401 westbound, and a directional ramp for the opposite movement. The existing underpasses for the Highway 403 to Highway 410 link have sufficient right-of-way to accommodate the addition of a new HOV lane to the Highway 403 eastbound collectors that would tie into the expanded Highway 410, as well as the approach to the loop ramp to Highway 401 westbound. Construction commenced on these links by 2017.
