Welcome to The Roader's Digest - the SABRE Wiki, the most complete archive of information on the British and Irish road networks on the web.
Whether you want roads from the A1 to the R999 and ZC163, road features and designs, street furniture or mapping history, we have it covered, although not always as completely as we'd like. This is where you come in! If you find an error, omission or just feel you can add to the Wiki, why not help out? Any SABRE member can add and correct information, so please dive in, if you're looking for somewhere to start, try the main help page as your first port of call.
