What is the green fence for, seen on the verge of the M6 just north of Wigan It's about 18 inches high, and is for about half a mile between two bridges. Also on the other side of the motoway. It looks like its made of rigid plastic. I've seen similar barriers near new projcts to confine and capture newts, but they were polythene.
The area has not been coned off 'till recently, looks like they are removing the stuff now.
Also in the picture is a pretty big boat on a low loader.
