The maps in this section provide a visual history of the motorway network, with a map for each year since the first motorway opened.
See which sections of road were open in that year marked on the map and arranged in order month-by-month where that information is available.
The maps owe their existence to John Brown who came up with the idea. They are produced using data kindly supplied by the UK Motorway Archive Trust, collected and collated by Peter Hewitt and Tony Priest.
To get started, select a year from the list across the bottom of the page or use the "next" and "previous" buttons to move through the years in order.
