Having recently been doing a bit of Motorway driving, including crossing the Severn Bridge, it reminded me of a page I stumbled across on wikipedia about English roads. There is a page which shows how roads are numbered, along with detailed pages about Britain’s Motorways.
Not quite sure why!
I’ve seen trailers for an up-and-coming documentary about Motorways – well, if you want a sneak preview (or at least alternative description) then have a browse of the Motorway pages on wikipedia – there is some interesting history.
(There are loads of UK related pages on wikipedia – see this list of lists for some!)
