A9 laybys

[mrssanta]

This is a question I always wonder about when driving on the A9. Does anybody know why the laybys are numbered? Or indeed, why they are not numbered on any other A roads?

Good question, I have wondered that myself I think it's to assist with locating breadowns and accidents etc. (in some remote areas prone to poor road conditions)
The A9 and the line it takes now from Perth to Inverness is fairly unique in it was a long distance route built pretty much as one plan with all new laybys planned into the route and I guess someone had the good idea to number them.
I think the numbers stop at the Cromarty bridge or they used to.
Be good to hear if anyone has more info or different info on the reason for them

This makes sense to me tbh. Anyone breaking down somewhere like Drumochter pass in Winter would probably want to see a recovery vehicle sooner rather than later.

Thanks for your thoughts. Much what I was thinking, and it is very useful especially for knowing where to park for the various Drumochter Munros.

Going by the marker posts other roads have, it's as you're thinking.
When you're in the middle of nowhere it gives a guide to your position.

Assuming they are numbered heading north, it's like a stairway to heaven
