Arundel Alternative

Save Arundel’s countryside

New plans for the A27 Arundel Bypass will devastate Arundel, surrounding villages, beautiful countryside, and the South Downs National Park. All six proposed options are for 70mph dual carriageways which would severely damage the environment. Highways England is consulting on these plans until 24th October, 2019. Please respond to the consultation, and join us in supporting
a less damaging solution: the Arundel Alternative.

 What is the Arundel Alternative?

The Arundel Alternative would be an uninterrupted, 40mph, wide single carriageway, between the Ford Road roundabout and Crossbush junction, avoiding current pinch points to improve traffic flow, with minimal or no widening west of Ford Road roundabout.

Route details

Pinch points renumbered2.jpg

crossbush junction

From the east, the Arundel Alternative continues under a remodelled Crossbush junction, removing signals which cause holdups to the east. Access to Arundel and Lyminster is via existing roads.

Avoiding pinch points

From Crossbush Junction, the new road continues over a new rail bridge, avoiding five pinch points at:

1) Warningcamp junction, 2) Arundel rail station, 3) bus stops, 4) signal pedestrian crossing, 5) Causeway roundabout, which together cause holdups to the west at Chichester Road and Ford roundabout.

The short stretch of new road would meet the existing route
by Fitzalan Road junction. The river bridge is upgraded and Chichester Road has marginal (if any) widening.

Ford roundabout

With two lanes, Ford roundabout is comparable to other roundabouts along the A27 with some flow limitations, but it is not a key source of holdups. There are several options for shaping the area to improve traffic flow and walking and cycling access. These may include:

Keeping the roundabout: reconfiguring lane space would enable vehicles to leave at the A284 junction more easily. Restricting access at Maltravers Street junction would limit town through-traffic and improve roundabout flow. Walkways can be expanded around the roundabout and a footbridge provided across Chichester Road.

Remodelling for a through road: (see illustrative potential layout) where the new single carriageway continues across the junction with an underpass linking Ford Road and A284. The A27 would be raised less than a metre and space turned to a green area. Safe walking and cycle links through the underpass parallel the existing river-side pedestrian underpass.

Further transport measures

The Arundel Alternative and any Ford roundabout schemes should be implemented alongside further transport measures that include walking and cycling links to Ford station, planned infrastructure on West Coastway rail, and improvements to bus services to Worthing, Littlehampton and Chichester. Together, these transport improvements benefit all residents and business, not only those with access to a car.

Why is the arundel alternative less damaging?

The Arundel Alternative follows part of  the same line as two of  Highways England’s options, Cyan and Beige.

The Arundel Alternative is a wide single carriageway 40mph road that is affordable and deliverable and meets future traffic needs.

Cyan and Beige are 70mph dual carriageways that are very costly, highly damaging, and would increase traffic and carbon emissions.


  • Pinch points slow road traffic at busy times.

  • The road limits walking and cycling access at Arundel.

  • The bridge over the railway is narrow, dangerous and in poor repair.

  • Hold ups cause rat-running and air pollution in the town.


  • Remove all interruptions for free flowing traffic on the A27.

  • Improve safety as wide single lanes provide visibility and access.

  • Cut rat-running within Arundel.

  • Improve cycling and walking access across town and to the railway station, and easy car access for Burpham, Warningcamp and Crossbush.

  • Do not damage the South Downs National Park or its wildlife.

  • Do not damage villages and businesses or lose trade in Arundel.

  • Minimise new traffic and carbon emissions.

More reasons to support the
Arundel Alternative



The UK parliament has declared a climate and ecological emergency. Major new roads increase carbon emissions, as do all six of Highways England’s options.

Induced traffic

‘Typically, new roads lead to new journeys, filling up the additional space’ (National Infrastructure Commission)

Increased traffic from a 70mph, dual carriageway scheme at Arundel would increase delays at Fontwell, Worthing and Chichester. By contrast, the Arundel Alternative would allow traffic to flow without adding to congestion.

economic and planning constraints

The Arundel Alternative is the most likely solution to be affordable economically, and to be acceptable to the Planning Inspectorate because it is far less damaging.

storrington and downland villages

To try to improve Storrington’s air quality by devastating villages and countryside at Arundel is too great a cost. A bypass at Arundel is unlikely to solve Storrington’s problems.

the ecological crisis

A dual carriageway would sever habitats and push wildlife species towards local extinction. It would also increase flood risk.

protecting carbon stores

We cannot afford to lose carbon stores like woodland and wetlands, by destroying them with new major roads. The Arundel Alternative protects both woodland and wetlands.

protecting the economy

Popular walks, views, wildlife and tourist businesses would be severely damaged by Highways England’s proposed dual carriageway options. These would be protected by Arundel Alternative.


The Arundel Alternative should be part of a low-emission, co-ordinated transport plan, including public transport, walking and cycling, which would benefit everybody.


why we can’t support highways England’s options for the A27 Arundel Bypass

Highways England’s options

All six proposed options are for 70mph dual carriageways which would increase traffic and carbon emissions and severely damage the environment. Ancient Woodland, villages and communities, Arundel’s watermeadows, rare chalk streams, historic parkland, endangered species, diverse wildlife, local business, carbon stores, beauty and tranquillity are all at risk.



Damages Arundel, Ancient Woodland, the South Downs National Park, and causes severance as high speed dual carriageway.

Cost range: £200 - £295m


Damages Tortington village, a large amount of Ancient Woodland, and the South Downs National Park.

Cost range: £255 - £380m


Damages Tortington and Binsted villages, Ancient Woodland, broadleaved woodland, historic parkland, and the South Downs National Park.

Cost range: £290 - £420m



Damages Arundel, Ancient Woodland, the South Downs National Park, and causes severance as high speed dual carriageway.

Cost range: £195 - £290m


Damages Tortington and Binsted villages, Ancient Woodland, broadleaved woodland, mediaeval tile kilns, and the South Downs National Park.
