M25 Motorway, when traffic announcements are broadcast regarding accidents and and slow moving traffic,?

Question

they always mention ' in a clockwise/anticlockwise direction'. How can this be figured out easily? We live close to J21a, and there are often problems in this area. But I can't figure out how to work this out.

Answer 1

The numbers of the junctions get higher in a clockwise direction like on the face of a clock.

If there is congestion anticlockwise from 21a that's towards Heathrow (west), if it's clockwise its towards the Dartford tunnel (east).

I'm not sure if that's any clearer or not!

Answer 2

From Jn 21a, if you are heading for say, Dartford you are going CLOCKWISE - towards the 'high numbers'. If you are heading to Heathrow and beyond you are going ANTI-CLOCKWISE - towards the 'low numbers'.
