The Dun valley is an important transport route through the high chalklands between the London Basin
to the east and the Vale of Pewsey
to the west. It is the route by which the Kennet and Avon Canal
(linking London

) enters the Thames basin from the Vale of Pewsey, crossing the watershed with the aid of the Bruce Tunnel
and Crofton Pumping Station
. The later Reading to Plymouth railway
linking London and the south-west also uses the valley.
