A22 road The A22 road is a primary arterial route linking Eastbourne on the English Channel coast with the southeast approaches to London, passing through Lewes, Uckfield, Haywards Heath and Caterham. It connects coastal ports, commuter towns and rail hubs, intersecting strategic routes such as the A23 road, the M25 motorway and routes toward Gatwick Airport. The road serves as a corridor between the South Downs National Park and the Greater London conurbation, carrying long-distance, regional and local traffic.
Route
The route begins at Race Hill, Eastbourne and proceeds westward through the built environment of Eastbourne toward Willingdon. It skirts the northern edge of Seaford and ascends through the South Downs into the High Weald, intersecting the A26 road near Lewes and passing close to Lewes Castle and the University of Sussex campus at Falmer. Continuing northwest, the road links Uckfield—with rail connections to London Bridge—and crosses the River Ouse (Sussex) tributaries before reaching Haywards Heath where it meets the A272 road and the A23 road interchange towards Brighton and Croydon. North of Haywards Heath the alignment traverses the northern rim of the Weald, serving Dormansland and Godstone before descending into Caterham and the urban fringe of Croydon. The final sections approach the M25 motorway interchange and feed into radial routes toward central London, the Blackfriars Bridge sector and commuter corridors to Charing Cross.
History
The corridor follows medieval and early modern coaching routes between the Port of Newhaven and London Bridge; elements of the modern alignment trace turnpike-era improvements authorized by 18th and 19th-century acts including connections to the Brighton Main Line that altered intermodal flows. Victorian railway expansion—particularly the construction of the Brighton Main Line and the East Coastway Line—shifted long-distance passenger traffic away from road, leaving the corridor as a freight and local arterial managed under successive County Councils including East Sussex County Council and Surrey County Council. Twentieth-century developments such as the opening of the M23 motorway and later the M25 motorway redefined junction priorities; wartime logistics during the Second World War also prompted hard-surfacing and bridge works on key crossings. Late-20th-century bypass projects at Uckfield and incremental safety schemes reflect post-war traffic growth, while heritage conservation in the South Downs National Park has influenced modernization proposals.
Junctions and features
Key junctions include the intersection with the A26 road near Lewes, the grade-separated interchange with the A23 road at Bolney serving the Brighton corridor, and the link with the M25 motorway at Junction 6/7 interfaces. Notable structures are river bridges crossing the River Ouse (Sussex), stone viaduct approaches influenced by Isambard Kingdom Brunel-era masonry elsewhere, and the steep climb over the South Downs escarpment which imposes heavy-vehicle restrictions in severe weather. Architectural and cultural features along the alignment include proximity to Lewes Castle, Arundel Castle sightlines from the hills, and settlement centres with listed buildings overseen by Historic England. Service areas, lay-bys and park-and-ride nodes connect with rail stations at Uckfield railway station and Haywards Heath railway station, while traffic control equipment is maintained by National Highways and local highway authorities.
Traffic and safety
Traffic volumes vary from high-density commuter flows in the Greater London approaches to seasonal spikes near Eastbourne driven by seaside tourism and events at Beachy Head. Freight movements include agricultural and port-related goods serving Newhaven Port, with HGV restrictions applied in conservation areas. Collision patterns recorded by regional police forces show concentration at junctions with the A23 road and on steep sections of the Downs during icy conditions; measures have included average speed cameras, enhanced signage funded through schemes administered by Department for Transport grants, and engineering interventions guided by the Transport Research Laboratory. Air quality monitoring by county councils near urban stretches responds to UK Air Quality objectives and local sustainability initiatives.
Public transport and services
The corridor integrates with rail services on the Brighton Main Line, the Uckfield Branch Line and the East Coastway Line, enabling multimodal commuting to London Victoria and London Bridge. Bus operators such as Stagecoach Group and local community transport schemes provide interurban coach services linking market towns and villages, with park-and-ride facilities coordinated with Network Rail station car parks. Emergency services, including Sussex Police and Surrey Police as well as ambulance trusts, maintain response routes along the road; highway maintenance and winter gritting are contracted by county councils to ensure continuity of public transport during adverse weather.
Future developments and upgrades
Planned upgrades reflect a mix of capacity, safety and environmental objectives governed by regional transport plans from South East Local Enterprise Partnership and strategic planning authorities. Proposals under discussion include junction improvements to reduce congestion near Haywards Heath, targeted bypass schemes to protect village conservation areas, and technological interventions such as variable-message signs and expanded intelligent transport systems funded through Transforming Cities Fund bids. Environmental mitigation for developments must satisfy Environment Agency guidance on flood risk near river crossings and biodiversity commitments under the National Planning Policy Framework. Long-term scenarios consider integration with wider southeast freight strategies tied to Port of Newhaven expansion and rail freight modal shift initiatives advocated by Department for Transport and regional freight partnerships.
