Just had a Google, a BBC report of 27/6/11 states that the average cost of a motorway is £30m per mile; but the M74 extension in Glasgow cost £138m per mile and this is not the most expensive. Bridges and tunnels jack the costs up considerably.
I recall our teacher asking us, in the early 1950’s to state what were the advantages of railways compared to roads. Someone said railways would be cheaper to build, I thought he had a point, after all you only needed to drop a couple of rails down. The teacher didn’t agree.
Some years ago I was talking to a mechanic for a road haulage company that had a large fleet of container lorries travelling from the Midlands to Felixstowe daily, more or less nonstop, they were covering over 150,000 miles a year per vehicle. If they are still going, perhaps these will now go by rail.
