To the west the track can be detected below the escarpments of the Berkshire Downs. Near Wantage, the route along the ridge of the Downs is known as "The Ridgeway", and the name "Icknield Way" is applied to a parallel lowland route above the spring-line at the northern edge of the chalk. Between Lewknor and Ivinghoe there are two parallel courses known as the "Lower Icknield Way" and the "Upper Icknield Way". In Cambridgeshire, Street Way (Ashwell Street), Ditch Way and others have been put forward as variant routes, possibly for use in summer or winter.
