Hello there!

Welcome to the UK's favourite roads website. (formerly CBRD) is dedicated to the study of the entire road network of mainland Britain. These days there's a lot of information about the road network out there - but remains the biggest, the most comprehensive and the most frequently updated. It contains information on most aspects of the network and is frequented by enthusiasts, officials, engineers and everyday road users alike. I aim to make the information on the site accessible to everybody, both in the way it's written and the way it's presented. has no politics. It is not a pro-roads protest or campaign site. It is a reference site which aims to provide up-to-date and useful information on the road network of Great Britain. To find out more about the site and what it's trying to do, take a look at the About page.

I hope you enjoy the site!
