English B roads

[David H]

Is there a reason why B roads start at 100 rather than 1? My only theory is none are long enough to number enough low numbers.

Go to http://euclid.colorado.edu/~rmg/roads/numbering.ht
ml#history Scroll down to 'A Brief History of the numbering system' and all will be revealed.

Oops. Be careful, the word Scroll has got included in the web address. I wonder how that happened?

Thanks Dean, it was for this new page on my website http://groups.msn.com/davidskingsburycollection/di
dyouknow.msnw They still didn't really know why they started at 100, but I think there weren't enough B roads good enough to qualify, or they'd have been A roads. I also noticed A roads aren't always numbered lower for longer as the A 200 at Tower Bridge barely goes anywhere.
