Road Worker? Park where you like.

Jim's just mentioned work going on for resurfacing somewhere near Kylemilne Way, however this is causing him and other residents of Millfields fun as the work crew are parking their equipment up the end of their new road and, as we're dealing with resurfacing, leaving lumps of tar etc. behind as they trundle up and down.

So here's the question - as none of these roads on the estate have yet to be adopted and are thus classed as private property who gave the repair crew permission to use that area as a vehicle park?
