The A25 exits east from Guildford, soon crossing southwards over the North Downs at Newlands Corner, to run eastward below the southern edge of the North Downs, with the road's route alternating between the Vale of Holmesdale and the Greensand Ridge, passing through Dorking, Reigate, Redhill, Nutfield, Bletchingley, Godstone, Oxted, Westerham, Brasted, Sevenoaks and Borough Green. It crosses over the River Wey at Guildford, the River Mole at Dorking, the River Eden at Oxted, and the River Darent at Westerham. The A25 has junctions with several major London to south coast roads: the A24 at Dorking; the A23 at Redhill; the A22 at Godstone; and the A21 at Sevenoaks.
