An astonishing amount of money is about to be spent on a scheme that few would argue against - keeping the M25, the main artery around our capital city, flowing smoothly - as it is surely good for UK plc. So why, when we are so close the first spade being driven into the ground, do so few people know what is actually going to be done?
OK, financial close on the £5bn scheme has yet to be reached, but does that really mean the technical details must remain under wraps?
The Connect Plus consortium that will build the scheme say they are happy to talk - but only once financial close is achieved. The Highways Agency, the government agency that will be the client, are happy to talk - but only once financial close is reached.
So we are left with chinese whispers - rumours that designs are incomplete, rumours that instead of an extra lane we are going to get hard shoulder running in far more places than originally anticipated, and rumours that the work won’t be complete in time for the Olympics. Untrue, I’m sure. So why can we not be told - given the details about what is going to happen and when. Why the great M25 mystery?
