The Motorway Archive - list of motorways

Motorways in England, Wales and Scotland

Where a motorway number appears in blue, you can link directly to the "scheme description" page which includes it. Where the motorway number appears in red then it falls on more than one website page and you are advised to locate it by other means, possibly using the "search" facilities. The description of the remaining motorways is not yet available on the website.
