I got a little bit excited when I saw a notice in the local rag last week about a traffic order for a cycleway between Haddington and East Linton.
The online notice is published today and so I went along to have a look
http://www.tellmescotland.gov.uk/notices/east-lothian/traffic/00000111542/
but as you can see what it amounts to is designating a pre-existing footpath as a shared-use path. Another example of it being illegal to cycle on the pavements, except where it's not.
Apart from breaking at all the side roads, getting on and off at the Haddington end is particularly problematic where it breaks down to a series of footpaths skirting around two large motorway exit roundabouts. http://bit.ly/1H47o0y
Painful.
