Our solution for a Better Not Bigger A27 at Arundel

Real solutions call for integrated planning of infrastructure and services across the Sussex Coast. Scate’s New Transport Vision (at scate.org.uk) provides a plan for this. The plan also calls for smarter, less damaging road improvements at Arundel.

With this in mind and the concerns of local residents the New Purple Route has been designed by someone who is an Arundel resident himself.

The New purple route

An uninterrupted 40mph wide lane (5m), single carriageway road continues from the east under a remodelled split level junction, without signals, at
Crossbush. The junction provides access to Arundel and Lyminster, as at present. Continuing on a new rail bridge and avoiding pinch points at 1) Warningcamp junction; 2)station; 3) bus stops; 4) signal crossing; 5) causeway roundabout, to meet the existing road by the Fitzalan Road junction. The river bridge would be upgraded with marginal widening of Chichester Road. 6) Ford roundabout as the remaining pinch point, as a two (or more) lane roundabout, is comparable to other roundabouts the length of the A27. However, this Ford Junction can be improved with major remodelling.

Ford junction proposal

The Ford roundabout is a huge area, lending itself to reorienting the A27, providing a direct uninterrupted route for the main road at 40mph and an underpass for the continuation of Ford Road with Maltravers Street. The level of the A27 here would be less than a metre higher than the existing road at the roundabout. The underpass, at correct height, enables drainage, using existing drains, with a balancing pond, for potential flooding events.

In this design, slip roads have been allocated to enable all points of access available in the current arrangement. A significant area can be turned to green space and walking link through the underpass parallels the exising underpass by the river.

A27 Problems

There are six ‘pinch points’, causing traffic to slow or stop, on the A27 at Arundel.

  • Crossbush junction traffic lights
  • Railway bridge
  • Bus stop opposite station
  • Pedestrian controlled traffic lights by the railway station
  • Causeway roundabout
  • Ford Road roundabout.

Hold ups at these pinch points cause traffic to back up on the relief road and on the westbound Worthing Road approaching Crossbush.

Further flow and access problems occur at other points, including:

  • Burpham and Warningcamp
  • Batworth Park
  • Beefeater/Premier Inn
  • Crossbush village
  • Arundel railway station, builders merchant
  • Causeway houses

Queues are less frequent going westbound on Chichester Road or eastbound after the  Burpham turning and outside peak times, flow is reasonable.

Flow is the key issue rather than capacity.

Solutions

The benefits of the new ‘Single Purple’ proposal include:

  • significant improvement of traffic flows;
  • improved safety as wide single lanes permit visibility and  better access in case of incidents;
  • five of the six main pinch points at Arundel eliminated. The Ford Road roundabout remains and is comparable to others on the A27;
  • improved access to and from Arundel railway station;
  • safe access to villages, Burpham, Warningcamp, Crossbush;
  • relief of the old railway bridge and replacement in the A27.

Additional benefits of the proposal over other Highways England options include:

  • no loss of housing or business;
  • no loss or division of ancient woodland, or significant wildlife habitat;
  • limited impact on the landscape of the Arun Valley;
  • no new road in the South Downs National Park;
  • no further severance of villages or communities and continued linkage to the National Park;
  • reduced noise and air pollution (other HE options are acknowledged to increase pollution);
  • no loss of amenity, including popular walks;
  • reduced flood management issues
  • sufficient capacity, minimising generated traffic;
  • reduced impact on pinch points at Chichester and Worthing;
  • no loss of passing trade;
  • significantly lower costs than other HE route options.
