The road network across Wales and the rest of the UK has grown as planners have sought to enable more people to travel by car, van or lorry more easily and more quickly.
The Welsh Government has now published a set of criteria for any new road projects seeking funding in Wales that explicitly reverses this. No new road project in Wales will get funding if it will have capacity for more vehicles than the existing roads or if it will allow those vehicles to travel more quickly.
Wales' new criteria were published alongside the outcome of the Welsh Government's independent Roads Review Panel, which was announced on Tuesday, February 14 and effectively cancelled many of the biggest road building projects that had been planned to improve the nation's transport network.
