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.
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
A290	Canterbury	Whitstable
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.
