traveling up the m1 today and just wanted to know what the blue signs on the side of the moterway mean.they seam to be marked up in half mile gaps eg 170 then the next is 170.5 and they go up as you travel north

Do you mean the Distance Post Markers?

This - they are big versions of what's already written on the small marker posts. The idea is if you break down, or pass some debris and call it in, you can go "I've just passed the sign saying M1 A 207.5, which would be M1 (duh) Alpha carriageway (northbound), 207.5 (distance from the start point, in km).

Jct1 onwards is the Alpha carriageway. Travelling towards Jct1 is the Bravo carriageway.

I find it very interesting that someone took the decision to use Km instead of miles when they were installed.

They are actually all over the roads not just the motorways in Britain. Like the grass verge signs under EVERY overhead power line saying how high up they are.

[Mr Skrunts]

Used for motorway maintenance (also have other uses), they are distance markers to junctions so they know what equipment to bring fot say a 700 metre closure or 1.8 km closure etc.

Exciting journey by the sound of it.

If you can look at the speedo you're not even trying, let alone count the markers.

Interesting indeed. Isn't it time we went metric for everything now, I mean this is 2013 in the 21st century not 1900. We're almost being as backward as the Americans. Just how bonkers are Miles and Yards, Gallons and Pints, Stones and Pounds etc ? Actually many of our measurements aren't even the same as in the USA, so what's the point ? Probably all just national sentiment and resistance to change, not practical reasons.

Can't have a metric cricket pitch. 22 yds = 1 chain.......metricate that!

Anyway, you're the chairman of the anti decimalisation and binary protest something or other.....aren't you?

That's it confuse us old buggers, and what is wrong with imperial measurement. Do you really go into a pub and ask for 1/2 a litre of beer
Must mention it to UKIP

Oh dear ! There is the potential for a right 'ol logical rant here. However I'll resist the temptation and move on . .

Now, I think that we should drive on the right . . . .

Apparently there are only three countries in the world that haven't adopted metrication. USA and two others. It is a bit tongue in cheek as we in Britain still refer to many things in old measurements. In Spain larger plumbing fittings are in Imperial. Tyres on virtually all cars are in Inches for rim but metric for width.
