An 80 metre length of Chalk Lane is one-way northbound, preventing use by southbound cyclists wanting to avoid the busy A111 between Hadley Woods bridleway and Cockfosters Station, where there is a safe Pelican crossing onto the cycle track linking to Oakwood and beyond.
An 80 metre long contraflow for cyclists would fix the missing link and provide a safe and mostly off road cycle route all the way from Enfield to High Barnet.
London Cycle Design Standards state: "Unless there are over-riding reasons not to, there should be a presumption that contraflow cycling should be provided for in any one-way street." (4.3.9 Two-way cycling in one-way streets).
Chalk Lane used to be two-way until a new housing estate was built in Verwood Drive, when it was made one-way to stop too many cars emerging onto the A111 next to the tube and bus station. However, there is no reason to stop cyclists.
