Leeds, as a large city, was too large to accommodate all the potential traffic, and it should instead attempt to curtail access, particularly private vehicles being used for commuting.

Leeds embraced the approach and adopted the motto Motorway city of the 70s after it built an Outer Ring Road, a sunken part-motorway Inner Ring Road and a clockwise-only 'loop road' enclosing a part-pedestrianised city centre with several business and shopping centres.
The protection and redevelopment of the city centre came at the cost of the large landtake required for the network of corridor roads and interchanges, predominantly at ground level, which required extensive demolition and severed the previous urban and suburban communities.
