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).

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.
A282	Darenth	Thurrock	Part of the London Orbital (M25). Previously allocated to a road between Broadbridge Heath and Five Oaks (now part of the A264).
A283	Milford	Shoreham-by-Sea
A284	Houghton	Littlehampton
A285	Petworth	Chichester	May have been previously used in Charing from the A20 to the A252, but it was likely a typo as the number was already in use. Now part of the A252.

A287	Hook	Haslemere
A288	Southsea	Portsmouth
A289	Strood	Gillingham

A291	Sturry	Herne Bay
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.
A295	Hailsham	Amberstone, East Sussex	Previously allocated to a road between Dartford and Oxleas Wood (now A2 and Rochester Avenue; the old route of the A2 was partially declassified and the rest became part of the A207).
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.

A298	New Malden	East of Raynes Park

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.
A2010	Seven Dials, Brighton	West Street, Brighton
A2011	M23 J10	A23 at Crawley	The original one ran from the A3 south to Clarence Pier in Portsmouth (became part of the A288), and after this, ran from Ditton to Bearsted via Aylesford (now Station Road, Forstal Road, Sandling Lane, and Bearsted Road).

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.

A2018	Bexley	Dartford

What remained of the route was downgraded to Class II status as the B2233 in the 1970s.
A2025	South Lancing	North Lancing	From junction with A259, north to junction with A27 at Lancing Manor Roundabout.

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.

Route may be classified as the C460.
A2036	North of Bexhill	East of Bexhill
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.

A2074 - A2078			Unused
A2079			Number given to the section of former B2164 (now A2070) from M20 J10 to the A28 outside Ashford.

The number was reserved when the new grade separated junction was built as Titmore Lane was proposed to be improved to support new housing development, and would be numbered A2700 when works were completed. However these works never took place due to local opposition. The route remains signed at the A27/A280 junction, but is signed as "(A27)" at the A259/A2032 junction.
