Also exit here for East Grinstead, Redhill (A25), and Godstone. My recommended route to Croydon; but the Highways Agency have overlooked it - far better than the M23/A23 signed route. The next section to Junction 8 was opened in February 1976 and cost £10.4m. It was one of the first sections to be opened as M25 and not upgraded from all-purpose road.
