File:UK road A270.svg 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.
File:UK road A271.svg A271	Hailsham	Battle
File:UK road A272.svg 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).

File:UK road A273.svg 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.

The road originally followed what is now the A2029 into Lewes.

That road became part of the rerouted A275 after 1960, while the old route of the A275 became part of an extended A2029.
File:UK road A277.svg 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).

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.
File:UK road A280.svg 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.
File:UK road A281.svg 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.
File:UK road A282.svg 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).

File:UK road A284.svg A284	Houghton	Littlehampton
File:UK road A285.svg 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.

File:UK road A287.svg A287	Hook	Haslemere
File:UK road A288.svg A288	Southsea	Portsmouth

File:UK road A292.svg 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.
File:UK road A293.svg A293	Portslade Bypass and A27 junction.	Portslade
File:UK road A294.svg 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.

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.
File:UK road A2013.svg A2013			The original one ran along London Road, High Street, and White Post Hill through Farmingham along an old routing of the A20, and after this, ran from A284 to A259 (now B2187) in Littlehampton; this became part of the A259 in the 1980s when the bypass opened.

File:UK road A2028.svg 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.

This route is actually the A2050; the A2039 number has been found nowhere else, suggesting that it is a typo.

File:UK road A2700.svg A2700	Reserved		Ran along Titmore Lane linking the A27/A280 grade separated junction to the A259 roundabout with the A2032. 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. West Sussex Council sometimes uses the number to refer to the road in documentation, or otherwise claim the road is part of the C37.
