At the start of the 1960s, it was determined that the Circus needed to be redeveloped to allow for greater traffic flow. In 1962, Lord Holford presented a plan which would have created a "double-decker" Piccadilly Circus; the upper deck would have been an elevated pedestrian concourse linking the buildings around the perimeter of the Circus, with the lower deck being solely for traffic, most of the ground-level pedestrian areas having been removed to allow for greater vehicle flow. This concept was kept alive throughout the rest of the 1960s.
