That idea might not be as silly as it sounds, Luco !
My memories from the late 1950's; before my family emigrated to Australia; are that many of the major thoroughfares in Glasgow that I travelled on (Argyle Street, Dumbarton Road, St Vincent's Street, Clyde Street and Hope Street around Anderston; Govan Road and Craigton Road in Govan, and even parts of Great Western Road) at that time were cobbled streets. There were probably hundreds of others too (did trams to Maryhill, Possilpark and Springburn in the early fifties tavel along cobbled roads, too ? I seem to remember they did !).
That's only parts of Glasgow that I lived in or visited but (as many pictures on this thread show) I'll bet there's lots of other areas (north, south, east and west of the City Centre) where the old cobblestones have provided a terrific base for any new road.
But, because of course, if a modern conglomerate is employed to build a new motorway, then everything old has to be dug up and replaced !
