Detailed information on every motorway and A-road expressway in mainland Britain - its length and route, its history, construction dates, and of course a detailed strip-map of the whole road. You can also find Chronology Maps showing the development of the motorway network over time, and you can search more than 2,000 individual junctions and other features of the road network.
