    Can anyone link me to a cross section of the cycle path at St Leonards, or failing that anyone know the width of the two way cycle track? here: https://www.google.co.uk/maps/@55.9424198,-3.1790948,3a,75y,18.36h,72.66t/data=!3m6!1e1!3m4!1s1UjznC4YGkTvMO8HfhQE8w!2e0!7i16384!8i8192

    thanks in advance..

    There's an app a thread for that. Hasn't been prodded for a while though.

    Also useful data on design specs here:

    Dang - beaten to it by the ever efficient Arellcat! Just measured this using the google maps tool and it seems the St Leonard's Street lane is still 2m wide, which is the "absolute minimum width" for a kerb segregated two-way cycle lane set out in Cycling by Design - see page 54.

    Yes, it is sub-standard width. This was pointed out to them when the design went out to consultation. But they ignored anyway.

    And yes, I do worry that my 10 year old will have a head-on collision at this point.

    My understanding was that 2.5m was the desirable minimum, with 2.0m absolute minimum to be used in limited and very constrained circumstances ???

    Wow, CCE to the rescue and in some style!

    Based on design guidance for access for

    Disability - Selwyn Goldsmith RIBA/RAIS - 0.9m (0.8m pinch) to get wheelchair through with gradients (1:20 continuous/1:12 with rest platforms) and crossfalls (1:40 - as trike users will agree)

    Paths in Forest and Countryside - Forestry Commission & CCS - 0.9m dynamic envelope for most users at walking speeds making the minimum for a 2-way path 1.8m - also contains designs for bridges, notably the classic composite steel I beams with prefabricated brace & handrail frames & deck planks. Often poorly installed with threshold detail issues, and modern high friction strips replace the deadly chicken wire anti-skid treatment

    Sustrans (1980's standards) built a path base at least -.5m wider than the final path surface and used the 'structrual' shoulder in place of timber or concrete kerbs, and had a minimum of 0.5m - ideally 1.0m from path edge to nearest vertical plants or built elements, this maintained (ruthlessly) with high output machinery to 'lawn height' after wildflower seeds had set and birds fledged - roughly once a year (0.5-1.0Km/day)

    A firm grass verge sloping slightly away from the path surface drains the water, as well as supporting the path surface, and not trapping water, as the path sinks below the kerbs. The grass verges provide a colour and tactile contrast for the visually impaired and walking with on foot on surface one on verge. A clear verge is essential for a safe and easy to maintain path - plus building without having to build kerbs is faster and cheaper.
