A267 Tunbridge Wells Lower Dicker
A268 Flimwell Rye Previously allocated to a road in Cross In Hand from A265 (now B2102) to A267. This became a spur of the A267 when the current A268 was created, and is now a spur of the B2102. For a short time continued west to the then A266 in Ticehurst. Originally followed what is now the B2088 in Four Oaks.
A269 Bexhill Ninfield
A270 Southwick Coldean Lewes Road. Formerly part of the A27 before a bypass was constructed around Brighton in the early 1990s. Original alignment went from Sidley Green to Glyne Gap, and was renumbered the A2036 to discourage through traffic.
A271 Hailsham Battle
A272 Heathfield Chilcomb The road now takes a different route around Haywards Heath and not through the town as before (the old road is now the B2272). Original westerly end was at Stockbridge; this section became the B3049 when the road was rerouted along the middle section of the B3420. Originally followed what is now the B2102 to the then-A265 (now the B2192) in Blackboys; swapped routes when the A265 was downgraded west of the A267.
A273 Haywards Heath Pyecombe Previously allocated to a road between Ringmer and Golden Cross (now the B2124). The road number was reused on the current route (an upgrade of part of the B2028 and B2036, though was later rerouted around Burgess Hill) around the same time.
A274 Maidstone Biddenden Previously allocated to a road between Lewes and Pevensey (now part of the A27).
A275 Forest Row Lewes Original southernmost end was at Newhaven; the road was truncated to Lewes when the A26 was extended to Newhaven; this is now the B2193 and unclassified Kingston Road, Piddinghoe Road, and Lewes Road. The road originally followed what is now the A2029 into Lewes.
A276 Unused Originally proposed on Worthing to Newhaven; this became part of the A259 (and the B2109 from Newhaven to Eastbourne became the B259, but two years later became the A259) right before the numbering was finalized in 1922, and the number was instead used on the road from the A275 in to the A26 in Lewes that day. That road became part of the rerouted A275 after 1960, while the old route of the A275 became part of an extended A2029.
A277 Lewes Lewes Town Road, connecting the A26 and the A27; formerly part of the A27. The original alignment went from Brighton to Portslade-by-Sea (became part of extended B2066 and B2194).
A278 Rainham Bredhurst Previously allocated to a road between Felbridge and Horsham (now part of the A264).
A279 Unused Ran from the A281 south of Lower Beeding to Handcross. A spur (former A280) to the A281 was added in 1935. The A279 used to end at the A23 (now B2114) at the southern end of Handcross, but when Handcross High Street was bypassed, the A279 was extended along the old A23 to the bypass. Downgraded to an extension of the B2110 between 1993 and 1996, while the spur became part of an extended B2115.
A280 Findon Angmering Originally allocated to a road from A281 to A279 (now part of the B2110) in Lower Beeding; this became a spur of the A279 (now part of the B2115) in 1935 when the current A280 was created as an upgrade of part of the B2140.
A281 Guildford Pyecombe Near Cranleigh the road used to head south on what is now the B2130, Stovolds Hill, a now-destroyed road, and Dunsfold Road to Alford, where it rejoined the modern route. The road was rerouted with the construction of Dunsfold Aerodrome during World War II. Previously followed Old Guildford Road in Broadbridge Heath, and West Street and East Street in Horsham.

A283 Milford Shoreham-by-Sea
A284 Houghton Littlehampton

A288 Southsea Portsmouth
A289 Strood Gillingham
A290 Canterbury Whitstable

A292 Ashford M20 at Willesborough, Kent Previously allocated to Magazine Road in Ashford as an upgrade of the B2072. Later became part of the A28 (either as a spur or mainline), but is now unclassified. May have been used in Charing between the A20 and the A252 along the possible former A285 (also a typo), but was likely a typo for the A252.
A293 Portslade Bypass and A27 junction. Portslade
A294 Unused Ran between Chichester and Bognor Regis as an upgrade of the B2143. Renumbered as an extension of the A259 as part of the 1935 renumbering.

A296 Dartford Bean interchange, near Bluewater Former route of the A2. Originally allocated to Watling Street from the A226 to the A2 (now the current A296). Extended east over the old route of the A2 in 1972 and rerouted along the current route in 1978.

A2007 Ran from the then-A2 to the then-A259 in Dover via Priory Road. Renumbered A256 when Biggin Street was pedestrianized, but may have been a spur far earlier.
A2008 Ran along Scanlons Bridge Road in Hythe, linking the A259 to the A261. Now part of the A259 one-way system, but it remains two-way to allow traffic to head west without going around the loop.
A2009 Ran from A262 to A28 in High Halden, forming the third side of a triangle between the A262 and the A28. Became part of a rerouted A262, although the A2009 may have been a spur of the A262 before this.

First used from A223 (now declassified High Street) to A224 in Orpington (now part of the A232) and then Leatherhead to Fetcham (now B2122). It also may have been used near Hook connecting the A30 to the A32 as a replacement of a section of the A287, but this was probably a typo for the A3062. It became the A287 again in 1935.

A2017 Strood Strood North Street; signed as a spur of the A228
A2018 Bexley Dartford
A2019 Unused
A2020 Ran along the old A20 through Maidstone; created in 1961 when the section of the M20 between what is now J5 and J8 opened as the A20(M), but was renumbered in 1977 to its original designation of A20 when the M20 was extended. There was an earlier A2020, but its location is unknown.

A2024 Ran from Crockerhill to Climping as an upgrade of the B2144. The road was split in two by Tangmere Airfield during WWII, and was never replaced. The western half later became the B2144 again, while the eastern section was rerouted to link up with the A27 near Crockerhill. What remained of the route was downgraded to Class II status as the B2233 in the 1970s.

A2028 Ran along former A21 from the A21 (now B2211) to Sevenoaks; the southbound side followed the former A21 and the northbound side followed the former B2211. Renumbered as an extension of the A224 after the M25 was built. There was an earlier A2028, but its location is unknown.

A2033 A259 at Folkestone A260 at Folkestone
A2034 M20 near Channel Tunnel Folkestone
A2035 Ran from A2 via High Street (the old route of the A2) in Chatham to the A2; this became part of a then-new one-way system on the A2, except for one pedestrianized portion, but when the one-way system on the A2 was eliminated, the route was declassified except for the eastern end that is part of an A2 gyratory. Route may be classified as the C460.

A2037 Henfield Upper Beeding
A2038 Brighton Brighton
A2039 Ran along Park Hill Road from the A232 to the A212 in Croydon. Now part of the B243, although it is still signed as A2039 at both ends.

Number also appears on a Tourist Information sign in Canterbury, referring to the route that runs from the A2 to the A290. This route is actually the A2050; the A2039 number has been found nowhere else, suggesting that it is a typo.
