   “A widening of the M4 had long been mooted, and the Welsh Government had even earmarked most of the required £1.6bn funding for a new 14-mile, six-lane section around Newport. Then, in the face of opposition from environmentalists, came a realisation that similar road schemes across the world tend merely to encourage greater car use and therefore soon prove ineffective in solving the original problem.”
