I absolutely agree, and I will come to the issue of free flow later. The fastest transaction at the moment is the TAG, which takes six seconds, but there is further scope for helping with congestion.
Will the Minister tell us where the figure quoted in the public consultation of a 17% traffic increase over 10 years has come from? How much of that will be in the first year? In fact, it would be particularly helpful if he could publish all the research that the Government have commissioned on traffic modelling in relation to the end of the concessions and the traffic flows. I know that all hon. Members would be grateful for that.
If, as the consultation indicates, the Government decide to continue tolling, the toll level should not exceed the cost of operating the two bridges. Severn River Crossing collects about £90 million-plus each year, and that is going up. Maintenance and operation costs are between £13 million and £15 million. Based on a rough, back-of-the-envelope calculation, that requires a toll of about £1, which means the Government will still be charging three times more for cars and 10 times more for lorries. The Government argue that they will have to recoup a £60 million debt for fixing defects but, as the Welsh Affairs Committee has documented, they have done very well out of the bridges so far: the Treasury has received £154 million-plus since 2003 in unexpected VAT—more than enough to cover the debt and undertake the resurfacing work, which the Government value at £12 million, with a lot left over.
On the point made by the hon. Member for Ceredigion (Mr Williams), why do we have to pay for resurfacing on this stretch of road out of bridge tolls, when for any other stretch of road the cost is taken out of general taxation?
