Many thanks to Paul Gasson, Waltham Forest Cycling for providing these costings for cycling infrastructure. It is very useful for campaigners to have figures associated with local spends.
Copenhagen (or blended) crossing: £15-25k
Modal filter using bollards:
- bollards: £2k
- bollards plus 2 buildouts to protect parking: £10k
Sinusoidal hump: £2.5k
Tree pit & tree: £500
Planter
flush with footway: £500
in box container: £4k (via Marshalls), potentially cheaper if sourced elsewhere
Ban Private Cars in London 
Healthy School Street, a la St Joseph’s in Camden – £8,000
Camden says humps are a whole lot more expensive than the figure you give here – i.e. filtering etc. are really amazingly good value.

These figures are based on Waltham Forest Mini Holland so very reliable pricing from Paul Gasson of Waltham Forest Cycling. Glad sharing helps campaigners hold Councils to account
