Many old routes are not going to be practical or the cost of putting them back will be way more than they want to pay.
Money is one thing but i'm not sure the the will or imagination is around to make things really happen.
The regional mayors that are popping up as a smoke screen for handing back power to a local level.
Will just add to none joined up approach and the hit and miss the have.
Going on the one we have around here has declared a climate emergency, talks a lot about active travel and has appointed his own version of Boardman.
But then has signed off funding for a massive new road layout which carving up a urban park. The need based on traffic figures which are a bit open to question. Then signs off 1.2M for a motorway link road for a 1700 housing devolvement which is being sold as active travel friendly development.
We can only hope that the real change will come once people really start to climate change which is only going to worse and sooner than many think.
