I think I saw a couple of the old T and L route signs when I was there: Most confusing as the numbers bear no resemblance to the new N/R system!

Nothing whatever to do with electrical matters now, but it doesn't hurt to go off at a tangent every now and then: [Linked Image]

British roads are classified as A (primary) and B (secondary) routes. Some of the largest A-roads are classed as trunk routes and have a T suffix, e.g. A12(T). There is actually a very complex scheme as to how the roads were originally numbered, although to most people it appears to be quite random. Motorways (expressways) are designated with M numbers and blue signs.

French roads have N (National) and D (Department) numbers, the latter being the equivalent of our counties. Expressways have A numbers (Autoroute).
