 The south-eastern section of Ringway 4 between Wrotham and Sevenoaks was redesignated as the M26.Except for a deviation from the original plan around Leatherhead, the current M26 and the M25 between junctions 5 and 19 mostly follow the planned route of Ringway 4.The Godstone to Reigate section was opened in 1976 and the remaining sections of the southern Ringway 4 were constructed over the next ten years.
