M4 Motorway
Hi, Can any one tell me what the purple tubes, sticking up in the ground like mortar guns, are on either side of the motorway between Junctions 17 and 14. They appear to be flexi pipes of some sorts.
They are also in racks in the road work section. The intriguing part is that they are all sticking above ground at various heights.
It is bothering the wife, who in turn is bothering me!
Many thanks
