Great news that that the M25 widening to four lanes will be going ahead, despite the constant background noise from the anti-car, anti-roads lobby.

Appears there are some practical heads in the DfT and Whitehall who recognise that it might be a good idea to let Britons move around their country without suffering constant time-wasting snarl-ups.

There’s even a surprisingly instantaneous start to this massive £6 billion project, with cones due to appear already on the western section — between the M40 and A1. The second section getting an upgrade is between the M11 and A13.

Nothing like an immovable deadline like the 2012 Olympics to focus the political mind.

One major challenge remains, however, how to get drivers to drive on the inside two lanes of the widened motorway to make full use of the new road space?
