Chaos on the A264? No!
It has been said that preventing traffic using Cornford Lane would cause chaos on the A264 (Pembury Road).
This is not borne out by actual experience; during 2013 (and multiple times in past years) Cornford Lane was twice closed for periods of several weeks whilst gas main repairs were carried out and when kerbing was installed. There was no chaos on the A264. The difference was undetectable.
In comparison with the A264, Cornford Lane carries a very small overall percentage of traffic - a percentage that makes little difference to the A264 but that has a big impact on a narrow lane.
