I think the cycling folks at CEC must read CCE. Received this reply today, which (if you are reading) I hope the sender won't mind me sharing. (My bold below)
"CRAWFORD BRIDGE (ALBION TERRACE/BOTHWELL STREET)
Thank you for your enquiry, dated 12 November 2013, regarding the above location.
Crawford Bridge was previously illegal for cyclists to use and complaints had also been received from local residents/pedestrians about the behaviour and illegality of cyclists using the bridge.
However, the Council recognised the local and strategic importance of the bridge for cyclists and its use in providing an alternative, quieter, route for them. We therefore chose to convert the bridge legally to shared use for pedestrians and cyclists. The conversion has included repairs to the surface of the path and the addition of blue, shared use signs, to make clear the new designation.
In order to address the concerns that had been raised by pedestrians about cyclists, and to minimise the risk of collisions at the entry/exit points of the bridge (which have limited visibility for people joining from the sides), we installed chicanes to limit the speed which cyclists can reach at these locations.
Unfortunately the barriers at the Albion Terrace end of the bridge were initially installed too close together but this has now been rectified and, in response to complaints received from cyclists, we have chosen to further increase the space between the barriers at both ends to 2.5m. We consider that this provides adequate space for a variety of cyclists to negotiate, including those with trailers or child carriers, without compromising the speed limitation purpose of the barriers.
Please note that the barriers have been designed to enable them to be swung flush with the bridge parapet. This is to facilitate large numbers of pedestrians accessing/ egressing Easter Road stadium before/after football matches and we have let the Police know that this arrangement is in place.
Should you require any further information please contact me on the details provided below.
Yours sincerely
Project Officer (Cycling) Transport Planning"
So pretty much as I/we thought. Interesting though that both chicanes will be reset at 2.5m spacing.
