The A20 is a major road in south-east England, carrying traffic from London to Dover in Kent. Parts of the route date back to turnpikes established in the early part of the 18th century. The line of the road throughout Kent runs closely in parallel with the M20 motorway.
Traffic leaving London at first takes the A2 road; at New Cross in the London Borough of Lewisham the A20 begins and heads in a south-easterly direction, becoming in turn Lewisham Way and Loampit Vale. The latter road forms a large junction, where the A21 separates for Hastings. The road now runs through Lee High Road into Eltham Road, The junction with the A210 contains an unusually long 41 m yellow box junction. and continues as the Sidcup Bypass, crossing the A222 at Frognal Corner and the A224 at Crittall's Corner. Entering Kent, it runs past Swanley and flows directly onto the M20 motorway.
The A20 then passes the racing circuit at Brands Hatch before descending steeply from the North Downs escarpment past Wrotham and on to the county town of Maidstone. The route beyond Maidstone travels East, through the villages of Bearsted, Harrietsham, Lenham and Charing to Ashford.
