Arundel A27 Bypass – Latest Updates

Arundel A27 Forum is running a series of short talks on the  issues around the A27. Our 2nd talk is:

The Highways England public consultation on the Arundel A27 Bypass has now formally closed. Highways England is expected to announce their preferred route option in the spring 2018, with a consultation on the design to follow.

The consultation brochure and the list of public consultation events can still be found here.

Highways England (HE) has been commissioned by the Department for Transport to draw up options for A27 route improvements at Chichester, Arundel and Worthing as part of the government’s Road Investment Strategy.

Current favoured options, as discussed at HE ‘stakeholder’ meetings, can be seen here. They are all full scale, four lane, high speed, dual carriageways. These options have all been rejected in previous years as environmentally highly damaging and costly.

The Arundel A27 Forum is looking for a more measured approach to improvements, taking all factors, including long term traffic impacts, traffic flow and new technology into account.

The Forum proposes that a less damaging bypass route to be included as an option by HE for consultation in 2017. We’re calling this the  single carriageway ‘New Purple’ route.

The single ‘New Purple’ bypass

This is based on a Highways Agency (now HE) route option recommended for inclusion in consultation in 2006. It is brought up to date with current transport thinking.

This new option would improve A27 traffic flow significantly. It addresses safety and pollution issues, minimises impact on the Arun Valley landscape and enables easy access to Arundel and the nearby villages. Visit the Problems and Solutions page to see the issues behind this proposal and its benefits.

There are additional measures suggested to improve local links connecting the town for walking and cycling and better access to public transport, including road and rail. This would help reduce peak time road congestion.

A key factor is the route is a two lane road with five metre wide lanes, rather than four lanes.

This extra lane width improves visibility and safety and allows continued access in the event of a traffic incident while minimising induced traffic. A speed limit of 40mph optimises flow and capacity and reduces pollution over the relatively short stretch of single carriageway.

Proposed improvements

  1. The junction at Crossbush would be fully developed as a raised, standard, two level junction, as originally planned, eliminating the need for traffic lights. Traffic can leave or join the A27 at this junction via left hand lane slip roads, providing access to Arundel (and Crossbush) and Littlehampton (and Lyminster).
  2. The A27 continues under the Crossbush roundabout as a wide single carriageway road (two, five metre lanes) road at 40mph, to a new bridge over the railway line. There are extra lanes only where slip roads are required for the Crossbush junction access.
  3. The new road joins the present relief road just before the junction with Fitzalan Road (south side) and progresses to the bridge over the river Arun and to a remodelled, at level, Ford Road roundabout. The wide lanes can be continued across the existing (or rebuilt) bridge and new, separated, pedestrian and cycle crossings added to the outside of the bridge structure. Either pedestrian crossing can be accessed via existing underpasses on both sides of the river.
  4. A remodelled Ford roundabout would be the only pinch point, but as a two (or more) lane roundabout, similar to other roundabouts along the length of the A27. Additionally, a radical redesign of the roundabout area has also been proposed providing an uninterrupted A27 route, with direct access between Ford Road and Maltravers Street, returning some road space to green space.

  5. Chichester Road (Hospital Hill) has scope for widening to maintain a five metre lane width to the dualled section beyond the White Swan without impacting on woodland to any significant extent or on gardens. Lane provision to turn into the hospital would be provided to avoid hold ups and ensure safety.
  6. Car access is not retained on the old relief road, which would otherwise generate another pinch point. The old road can provide a separate cycle and walking route to the Causeway and Arundel station from the river crossing.

Additional measures

The Highways England discussions with stakeholders maintained that ‘sustainable transport’ elements, will be included. These would normally include measures to improve walking, cycling and public transport and travel planning support, but as the public consultation commenced appear to include only a few, limited cycle routes.

This single ‘New Purple’ proposal includes local walking and cycling routes and public transport, information, guidance and smart technology features.

Walking and cycling

Facilities avoiding the A27 and reducing ‘severance’ (division of the town by the road), involve:

  •  Ford Road crossing and improved path under the A27 river bridge, providing continuous access from Ford Road and Torton Hill to the High Street.
  • A pedestrian/cycle bridge from the bottom of Canada Road over Chichester Road to the Waterwoods, crossing from the A284 London Road and joining up to Mount Pleasant, to provide a safe, more direct route to schools, cathedral and surgery.

Public transport access

  • Improved access to Ford station with an off-road path for walking and cycling from Arundel, along with improved parking facilities at the station. This will enable increased coastal rail commuting and student travel.
  • Upgraded coastal rail and bus infrastructure, including longer trains and platforms, increased frequencies.
  • A fast A27 bus route with parking for bus stop locations to enable village access to services. Improved information, to improve commuter choice. Commuting is the major journey type during peak time traffic.
  • Tailored support for business travel planning measures, particularly for larger organisations like hospitals and educational institutions to reduce commuter traffic. Examples of measures include flexible working, peak fare discounts, rotational parking, car sharing, independent buses, active travel for health programmes and personalised travel information.

Support, ideas and questions are invited on the single ‘New Purple’ route concept and associated transport measures.
