I was struck by Geoffrey Bills' observations about the 50mph restriction on the Esher bypass.

Something similar occurred in St Peter's Way - the main link from this area to the M25 and St Peter's Hospital some time ago.

Since its opening, this dual carriageway - also built through green belt land - had the national speed limit, but then extensive disruption was caused by works to build a central safety barrier on the land between the two carriageways.

This seemed a reasonable idea for safety, yet once completed a 50mph speed limit was imposed.

How can this make any sense? Either the perceived safety risk was reduced by the new central barrier, so there could be no logic in a 30 per cent speed reduction, or the whole barrier was a huge waste of time and money?

We now have the worst of both worlds. Who makes these decisions?
