White poles appearing beside DC junctions

Amtmann

Has anyone else noticed white, capped poles, no more than 2m tall, installed recently beside dual carriageway junction ramps?

I've noticed several on the N22 Ballincollig Bypass and a few at M8 junctions.

Any idea what they're for?

Ramp meters?

OR

Wrong way lights/barriers?

Sounds like something I noticed on the M18,
if so, they mark the location of an underground gas pipeline.

They have hats so that they can be seen from a helicopter after the apocalypse.

I assumed they were some kind of gas vent from underground pipes / ducts.

It's possible that there's some new regulation that requires them to be installed over gas pipes or something.

Could they be ordnance survey total stations for use in land surveys

They're on the M50 junction from the N4 westbound but they're green and white as if to show arrows i.e. where the lane splits for SB and NB

Any pictures??

I spotted a few of these, they have labels on them that mention Gas, so probably some kind of vent.

Will take a pic of the one on the N22 over the weekend if the road is quiet.

They aren't vents. They are marker posts to show the route of high pressure transmission gas piplines, usually put at road crossings and ditches. The used to be a timer stile, then a concrete post as in the pdf posted eariler, now the white post with a cap on top. The routes are flown by helicopter to see for near by digging. Their is usually a sticker high up the post under the cap.

Sounds like a stupid regulation (having poles to indicate Gas). How much is this quango scheme costing? What a waste of money - could be spent elswehere like on bus shelters, signs, tarmacking.

These are high pressure pipelines not domestic supply's. Take a look on youtube on what damage they can do. You would be replacing a lot of bus shelters if it was hit

They can just use a map like everywhere else in Europe. They don't need super-simplified and very expensive navigation poles to view from the sky. They are supposed to be pursuing lean ways of maintenance - not flying around sightseeing in a helicopter. Anyway, don't get my blood boiled. I wouldn't touch Bord Gais if they were the last in the world.
