July 7th – Oh my goodness, this is geeky. But it appeals to my sense of the absurd. This road sign on the ‘old’ A5 near Mile Oak isn’t unique, but it’s certainly rather unusual. What makes it so is not the restriction and advice it gives, but the accidental inclusion of the road number C0036. Just about every road in the UK has a number to the Ministry of Transport (or whatever it’s called these days) and to the local authority, but in theory, only the familiar A and B class roads are allowed to be marked on signage.

There are, actually, five classes of road – A through D, in order of major to minor, and U, meaning unclassified, even though they actually are. Maps for public consumption only use A&B, and the remaining numbers are intended for administrative use only, but occasionally, in cases such as this, due to CAD or administrative errors, a C or D number will creep on to a sign.

This one has been in place since the bypass was built, a good few years ago now, and always raises a wry smile.
