Refocus of article[edit]

Now that we have Roads in the United Kingdom along with the roads list I have cut a lot of the duplicate information and am trying to refocus the article on the numbering scheme. I am really struggling for sources on this, but am adding them as I find them. I would appreciate thoughts, comments about what the scope of the article should be? Do we need a separate Road Network article describing the important A roads for example and keep this purely to the numbering scheme or should we keep them together?

Clear up wording[edit]

"The first digit in the number of any road should be the number of the furthest-anticlockwise zone entered by that road." That sentence is one of the most important in the article, because it gets at the heart of the matter of how roads are numbered. But I'm confused (I'm not a Brit) by what is meant by "furthest-anticlockwise." It's a radial pattern; you can go anticlockwise around and around. So furthest from WHERE? Furthest from the 1/6 and 9/7 boundary (in which case you could just say "lowest-numbered zone")? Thanks. 99.37.211.190 (talk) 16:41, 23 October 2009 (UTC)[reply]

I struggle with that wording myself sometimes, but I can't think of a good alternative. What it is trying to say is if a road is in zone 6 and zone 5 the furthest anti-clockwise zone on the London radial is zone 5 so the road starts with 5; for a road in zones 5 & 4 the furthest anti-clockwise is 4; zones 4 & 3 produce a 3 road; 3 and 2 produce a 2 road; 2 and 1 produce a 1 road. However "lowest-numbered zone" would not work because a road in zone 1 and 6 produces a 6 road. Road Wizard (talk) 18:10, 23 October 2009 (UTC)[reply]

'M3 was due to head towards Exeter'[edit]

I am going to remove the following sentences.

The latter two might be explained by the original plan for the M3 motorway, which was due to head towards Exeter, rather than Southampton as it does now.

The M3 was never considered to go to Exeter (although it oddly turns southwards near Basingstoke). The only route proposed following that line was proposed in 1936 by the Institute of Highways Engineers.

The original committee which set up the motorway zones chose the boundary of zones 2 and 3 to be the projected line of the M3 towards Exeter, although it's not currently known whether this is still the case.

As above, it was never meant to go there. The boundry between the motorway zoning system lies along the current M3. http://cbrd.co.uk/indepth/roadnumbers/motorways.shtml
