The A27 is a major road in England. It runs from its junction with the A36 at Whiteparish (near Salisbury) in the county of Wiltshire. It closely parallels the south coast in Hampshire, then passes through West Sussex and terminates at Pevensey (near Eastbourne and Bexhill) in East Sussex.
It is one of the westernmost Zone 2 roads in the UK.
Historically, for longer distance movement along the south coast, the M25 in combination with the M2, M20, M23 / A23, A3 / A3(M) and M3 has provided an attractive alternative to the actual south coast route of A259, A27 and M27. In 2002 an offpeak journey between Margate and Southampton via the M25 took 2 hours 30 minutes, and via the coastal route using the A259, A27 and M27 took 3 hours 50 minutes. The reason why the coastal route is so much slower than the M25 alternative is largely due to a series of bottlenecks on the A27. These include Chichester, Arundel, Worthing and Polegate.
The British government announced, in its 2013 spending review, that it would go ahead with improvements to the Chichester bypass. The Highways Agency said that the proposals would be subject to public consultation in July 2015. The preferred route would then be announced in September 2015 and the plan would be to start construction in February 2018 with a completion date of December 2019. However the timescales were then revised. There was a six-week public consultation period during Spring 2016. The proposed construction would then commence in March 2019 with a completion date of March 2021. After five options were published and two dropped the government cancelled the whole project on 28 February 2017, citing lack of support from local authorities as the main reason.
A proposed scheme to bypass Lancing and Sompting (as well as other sections) was dropped in 1988.
A proposed scheme to bypass Arundel was dropped in 2003, although the junction at the end of the dual carriageway has been partly made into an underpass. However, the scheme was re-launched in Spring 2018 when Highways England announced their preferred route, choosing a "a modified version of Option 5A". Although the document claims 48% of respondents support this option, there are worries that the new road may damage ancient woodland in the South Downs National Park.
At Worthing, where the possibility of a bypass has often been discussed since 1967, even getting as far as passing the inspector's report at a public inquiry, the plan was dropped in 1996 following rising costs. Arundel and Worthing are both areas of known traffic congestion during times of peak usage.
A bridge over the level crossing at Beddingham was completed on 22 August 2008. The original proposal called for a dual carriageway standard link with a bridge over the crossing. However, the actual project involved improving the original single carriageway road by providing two lanes westbound and one lane eastbound between the Southerham and Beddingham roundabouts.
Despite the limited improvements to the A27, it is still substantially quicker (usually more than an hour difference) to travel from Southampton to Margate via the M25 route compared to the coast route of A259, A27 and M27.
Because of all the delays along its route, according to West Sussex County Council, the A27 is the most unreliable all purpose trunk road in England. Further, it is widely considered by businesses on the coast to cost money and inhibit economic performance due to its unreliability and frequent congestion.
Highways England commissioned a report by "Transport Focus" to undertake road user priorities. The South Central route, that is largely the A27, was one of the lower rated routes with 50% of users experiencing problems. Out of a list of strategic routes across the whole of England only two were rated worst than the South Central route, these were the M25 to Solent route (61%) and the London Orbital and M23 to Gatwick (58%). Further Highways England identified the A27 between Lancing and the A24; between Arundel and the A284; between the A23 and Polegate; also around Chichester as being some of worst performing links in the country for safety issues. One accident victim was Actor Desmond Llewelyn, who portrayed Q in a large portion of the James Bond film series and was fatally injured in a car accident on the A27 in 1999, at Firle, on the A23 to Polegate section.
There are several sections of the A27 that fall inside the Highways Agency nationwide top 250 collision rankings:
- A27 between Shoreham-by-Sea and Southwick – ranking 123
- A27/A23 junction Brighton – ranking 158
- A27 near the junction with the A2025 near Lancing – ranking 158
- A27 Chichester By-Pass east of the city – ranking 202
Shoreham Airshow crash
At the Shoreham Airshow on 22 August 2015, a Hawker Hunter crashed into the A27, striking several vehicles and killing eleven people. The road was completely closed for eight days and did not fully reopen until 16 September 2015.
The road starts at its junction with the A36 at Whiteparish. It runs through Romsey, Chilworth, at which point it follows a Roman Road, Swaythling, West End and Bursledon. It then closely parallels the south coast and travels on via Fareham, Cosham, Havant, Chichester, Arundel, Worthing, Lancing, Shoreham-by-Sea, Hove, Brighton, Falmer, Lewes and Polegate where it then terminates at Pevensey in East Sussex.
A section of the A27 running from the eastern end of the M27 to the end of the road at Pevensey forms part of, what was known as, the South Coast Trunk Road. Much of the road has been improved to dual carriageway standard, with the westernmost section of the trunk portion even having as much as four lanes plus a hard shoulder in each direction, and on a motorway alignment with grade-separated junctions. This is perhaps a reflection that the M27 was once proposed to run as far as Chichester.
The road runs east from Portsmouth to Havant then on to the Warblington/ Emsworth exit. Beyond Warblington the dual carriageway east has no junctions in it until it reaches Chichester, where the by-pass has five roundabouts and one traffic signal controlled junction, that disrupt the mainline flow of the road. The Chichester by-pass is regularly subject to congestion and although a public inquiry has proposed improvements, those improvements are currently on hold.
East of Chichester the road largely retains a two-lane dual-carriageway standard. There are, however a couple of sections of single-carriageway; at Arundel and at Worthing. These are both areas of known traffic congestion during times of peak usage.
At the junction of the A27 and the A24, the A27 has a brief section where the road is designated 'A27' and 'A24' before continuing from the 'Grove Lodge' roundabout where the road is named "Upper Brighton Road". After Worthing, the A27 passes Sompting on the Sompting Bypass before passing through Lancing where there are traffic lights and a roundabout which disrupt traffic flow. Just before the road crosses the River Adur near Shoreham via the 'Shoreham flyover' (constructed 1968-70), there is a traffic light-controlled intersection close to Lancing College and the headquarters of Ricardo plc which was the scene of a fatal aircrash during the Shoreham Airshow 2015 on 22 August 2015, killing eleven people on the ground. After the 'flyover' over the Adur, the A27 then runs past the Holmbush interchange (Shoreham-by-Sea) and on through the Southwick Hill Tunnel, at that point entering East Sussex.
It then passes around Falmer with this section of road having three lanes in each direction but loses the third lane later. When Brighton and Hove Albion play at home this section can become congested due to its proximity to The American Express Community Stadium.
Here, the road becomes a single carriageway standard and, until 2008, crossed a level crossing until it was bypassed.
The South Coast Multi-Modal Study (SoCoMMS) recommended a dual carriageway, but the Highways Agency built it to a cheaper single-carriageway standard. Plans are still proposed for upgrading this later.
The road then once again becomes a single carriageway near Pevensey, where the road ends, and the South Coast Trunk Road transfers over to the A259; this coast road starts in Emsworth and shadows the route of the A27.

- In their 2013 spending review the British government said that they will fund a feasibility study that will include looking at problems on the A27 corridor.
- There is a recommendation to build a new road from Wilmington to Polegate.
- There is also a recommendation to make the road a dual carriageway between Beddingham and Polegate.
- On 1 December 2014 the UK Government announced that they would go ahead with proposed improvements to the A27. These were:
- Arundel to have a new dual carriageway bypass, subject to consultation with the National Parks Authority, local authorities and the publication of this and alternative options
- Worthing and Lancing to have improvements to capacity and junctions along the A27, subject to consultation with West Sussex County Council and the public.
- The original plan was for the four junctions on the Chichester bypass to be upgraded. However, other options were also considered.
- Some news organisations have been sceptical about this announcement, claiming that in the past "Governments have a habit of announcing big plans for the roads, only to shelve them later on when the money gets tight." There seemed to be some truth to this suggestion after the Chichester bypass scheme was cancelled, by the secretary of state, in February 2017.
- In Spring 2018 Highways England announced their preferred route for the Arundel Bypass.
