The story is that the original planners, when they willed the giant motorway under the town, wished to dig a tunnel for the cars so that none of the domestic harmony created by the several thousand adjacent hovels on the ground would have to be touched.

Here we are at Charing Cross in Glasgow and so much for that, because they tore them down. Two birds and one stone, old hovels gone away and new motorway placed in an analytic line from North to South.

The swathe of town they cut was over 100 metres wide, and at the point where I stand (and memorise this composition) the motorway is eight lanes deep and runs about thirty metres below ground level. The noise of all these engines thrashing at once is what attracted the planners to build this . . . yes, that and the fact that it may never stop.
