In reply to woolsack:
I spoke to Derbyshire County Council and the Peak District National Park Authority.
There's no TRO.
Just this width restriction until repairs can be carried out. Which won't be for nearly two years.
Hooray!
If you ask me that is a council using its powers in an intelligent way.
The vast majority of users, people, will breathe a sigh of relief.
Someone might need to spend some money on barriers though!
