Some thoughts on the Carrington Road scheme which is of interest to me as I use Carrington Road as part of my route to take the little ones to Inverleith Park/Botanic Gardens:
1. At 2.2m the width is below the minimum specified in the Sustrans Guidance and the Governments Cycle infrastructure design guidance. I use this route towing a child trailer which is 0.9m wide so would have concerns about hitting the kerb, other bikes/trailers coming the opposite way and overtaking bikes.
2. The scheme isn't proposing to do anything regarding the access to Inverleith Park. Negotiating the entrance on bike is already tricky. With a trailer it is a complete pain and this will get much worse if this scheme encourages more folk to travel by bike (which I hope it will).
3. Coming from the Crewe Road South side, the island in the middle of the road could quickly become congested if there are a few bikes there at the same time. A bit like the Hope Park Crescent lane, it also looks like they haven't allowed enough room for a bike with a trailer to perform the 90 degree turn which could leave me stuck half-in and half-out in a live traffic stream.
