As Reading has grown, its suburbs have spread: to the west between the two rivers into the foothills of the Berkshire Downs as far as Calcot, Tilehurst and Purley; to the south and south-east on the south side of the River Kennet as far as Whitley Wood and Lower Earley and as far north of the Thames into the Chiltern Hills as far as Caversham Heights, Emmer Green and Caversham Park Village. Outside the central area, the floors of the valleys containing the two rivers remain largely unimproved floodplain. Apart from the M4 curving to the south there is only one road across the Kennet flood plain. All other routes between the three built-up areas are in the central area.
