Yes and Yes, The council chapie says they are starting the section 5 (between new bit from last year to Burnshot Jct) in May for 16 weeks!
Section 3 is planned but they look to be in the 'wondering what to do' stage. So thya are canvasing opinion. There are threee basic designs,
3m wide path, with a grass divider between path & road,
2.5m wide path with armco barrier
2.5m wide with armco barrier and some sort of light barrier (like those green bars further into town on the A90), to stop light blinding cyclists. They recon typical cyclists are 1.5m high and were asking if the most light came from cars of road (reflected off surface in the wet).
