A27 (England) The A27 is a major east–west trunk road on the south coast of England connecting Honiton outskirts near Exeter to the vicinity of Pevensey near Eastbourne via a corridor passing close to Dorchester, Bournemouth, Chichester, Arundel, Worthing, and Lewes. It links regional hubs such as Plymouth-area routes, the M27 corridor, and the A23/M23 approaches to Gatwick Airport and Crawley, forming part of long-distance routes between the West Country and Greater London. The road serves ports including Portsmouth and Brighton catchments and interfaces with strategic rail nodes like Salisbury railway station, Chichester railway station, and Hove railway station.
Route description
From the western start near Honiton the route proceeds eastward through rural parishes adjoining Exeter and skirts market towns such as Dorchester before entering the Dorset coastline approaches near Bournemouth. East of Christchurch, the A27 continues into Hampshire, bypassing the New Forest fringe and intersecting with the major orbital M27 near Southampton-linked corridors and the A27-adjacent arteries feeding Fareham. Proceeding into West Sussex the dual carriageway bypasses historic settlements including Chichester and Arundel, linking to the A3(M) and providing access to Goodwood House and Chichester Festival Theatre. Further east, the route passes Worthing and skirts Shoreham-by-Sea and Portslade before reaching Brighton-conurbation approaches, the A23 interchange for Brighton and Hove Albion F.C. fans travelling from Gatwick Airport, and continues to Lewes and Polegate before terminating near Pevensey Castle and Pevensey Bay.
History
Origins of the corridor trace to Roman and medieval coastal tracks connecting Axminster, Dorchester and Chichester with ports serving Norman Conquest logistics and later Victorian era resort development at Bournemouth and Brighton. Twentieth-century upgrades paralleled expansions of Royal Navy facilities at Portsmouth and the growth of South Coast resorts promoted the road’s formal designation as a primary route in interwar classification schemes influenced by the Roads Act 1920. Post-war reconstruction, Ministry of Transport planning, and later Department for Transport interventions produced bypasses around Arundel, Chichester, and Worthing during the 1960s–1980s alongside junction works tied to the M27 and A27 realignments. Campaigns by local authorities such as West Sussex County Council and environmental groups including Friends of the Earth shaped later proposals, while Highways England decisions and National Infrastructure Commission advice influenced twenty-first-century upgrades linked to regional strategies for South East England connectivity.
Junctions and major intersections
Key interchanges include the link with the M5 near Exeter-linked approaches, the junctions with the A35 at Dorchester, connections to the A31 corridor near Ringwood/Bournemouth approaches, and the important interchange with the M27/A27 systems serving Southampton and Fareham. In West Sussex major nodes comprise the A3(M)/A27 junction near Havant influences, the Chichester bypass connections to the A286 and A259, the Arundel junctions feeding the A284 toward Midhurst, and the complex Worthing/Shoreham-by-Sea interchanges linking to the A23 corridor into Brighton. Eastern terminus connections include the A22 near Hassocks/Lewes and local links to A27 feeder routes serving Eastbourne and Bexhill-on-Sea.
Traffic, safety and improvements
Traffic volumes along the corridor vary from rural two-lane sections near Devon to busy dual carriageway stretches between Chichester and Brighton with peak-season surges from holiday travelers to Bournemouth and Brighton and freight movements to Portsmouth docks. Collision hotspots historically recorded near Worthing and the Arundel junction prompted safety audits by Sussex Police and junction redesigns funded by local growth deals involving West Sussex County Council and East Sussex County Council. Recent interventions include dualling projects, roundabout upgrades, signal optimisation schemes advocated by Highways England (now National Highways), and proposals considered by the National Infrastructure Commission to improve resilience and reduce accident rates, often coordinated with Environment Agency flood-risk assessments.
Public transport and cycling provision
The A27 corridor is paralleled by rail services on lines such as the West Coastway line and the Hastings line, supporting intermodal travel between towns including Hove, Littlehampton, and Bognor Regis, and by bus networks operated by companies like Stagecoach South and Brighton & Hove Buses offering express and local services. Park-and-ride schemes at strategic nodes near Chichester and Arundel integrate with bus services to relieve carriageway demand, while cycling provision varies: segregated cycleways exist in parts of Worthing and Lewes implemented under Local Transport Plans from West Sussex County Council and East Sussex County Council, whereas inter-town long-distance routes such as the National Cycle Network Route links provide alternative sustainable movement corridors.
Environmental and planning issues
Upgrades and bypass proposals have provoked environmental assessments addressing impacts on protected sites including South Downs National Park, Chichester Harbour, and areas of Special Scientific Interest like estuarine marshes near Pagham Harbour and Pagham. Planning decisions balance transport needs with heritage concerns for listed structures such as Arundel Castle-adjacent landscapes and conservation areas in Chichester and Lewes, often involving statutory consultees including Historic England and Natural England. Development frameworks tied to local plans from West Sussex County Council, East Dorset District Council, and Wealden District intersect with regional strategies for coastal resilience against sea-level rise monitored by the Environment Agency and climate adaptation guidance from the Committee on Climate Change.
