Reducing the Sir John A. Macdonald Parkway to two lanes west of Island Park Drive could divert as many as 550 vehicles an hour onto other roads, according to a preliminary analysis.

In a memo dated Feb. 1, 2016, engineering and management firm Morrison Hershfield provided the National Capital Commission with its interim findings on the traffic implications of reducing the parkway to two lanes from the current four between Island Park Drive and Carling Avenue.
