What Are These Strange Poles?

[MotorwayPlannerM21]

I found these on the M2 between junction 5 and junction 6. If anyone knows what they're for please tell me. To me they look like old signposts but what would they be doing in the middle of a motorway?


Sorry that they're on their sides, for some reason it rotated them!

I don't think they are original to the motorway as I saw them back in 1990 when the motorway there was completely reconstructed including the central reservation which was stripped back and rebuilt, my guess is that they're hazard markers left over from the construction work.

I've seen these on roads at relatively high altitudes. I've always assumed it's related to height or gradient, maybe a warning to drivers about going off route, but I'm not sure.

They're snow poles that you're thinking of.... designed to locate the road when snow's covering everything. I've been very glad of them on occasion when driving up towards Alston in wintertime...

The M2 ones definitely aren't those...!
