A259 Littlehampton improvements

Details of the design and construction of the improved A259 north of Littlehampton.

(Position at August 2020)


A lot of new housing and commercial development is planned north of Littlehampton in the coming years.

The Arun Local Plan recognises that expected development will only increase the current traffic issues. If these traffic problems on the A259 are not addressed, the positive impacts of increased access to new homes and jobs may not be achieved.

We have developed proposals to reduce congestion, improve journey times and reliability.

The first phase of works will include a new dual carriageway to replace the existing single carriageway between the new Fitzalan link road and the Body Shop roundabout and the single carriageway between Station Road, Angmering and the A280 roundabout. Later phases will see improvements to the Tesco Bridge Road roundabout and Goring Crossways junction.

The proposals will be funded from developer contributions, funding from West Sussex County Council (WSCC) and Government grants secured through the Coast to Capital Local Enterprise Partnership.

Proposed scheme

The project will widen approximately 2km of the existing single carriageway on the A259 to a dual carriageway. This is made up of two sections:

  1. From the new junction east of Wick roundabout, where the new Lyminster bypass and Fitzalan link road join the A259 from the north and south. This section will end at the Body Shop roundabout.

    A new pedestrian and cycle path will be installed to the south of the dual carriageway. Minor alterations will be made to the Body Shop roundabout to take into account the new, wider approach.

    The existing controlled pedestrian crossing points will be upgraded to Toucan (pedestrian and cyclist) crossings. Right turns across the carriageway, such as those at Olliver Acre and Cornfield Close, will be closed.

  2. From the Station Road (Blue Star) roundabout in Angmering to the A280 roundabout, including the Roundstone roundabout. This will feature a new cycling and pedestrian route to the south, separated from the main carriageway by a verge. The existing controlled crossing connecting Angmering School and Downs Way will be upgraded to a Toucan crossing. New Toucan crossings will be provided adjacent to the Station Road Footbridge and also near to Haskins, linking to a new westbound bus stop. Right turns across the carriageway, such as at Haskins, will be closed.

WSCC is working with contractor VolkerFitzpatrick to deliver the works. As far as is possible, the scheme will be constructed off-line from the existing road network to minimise disruption to road users during the works.


The overall benefit of these proposals will be to reduce current and future traffic congestion by increasing road capacity. The improvements will reduce queuing, resulting in quicker and more predictable journeys.

As well as benefits for motorised traffic, there will be approximately 2km of a new pedestrian and cycle route on the south side of the improved road. Much of this will be segregated from the road by a grass verge. It is intended that this will improve access to local facilities for walkers and cyclists.

Additionally, people will be encouraged to use the new footpath and cycle way to make local trips without using their car.

Strategically, the dual carriageway will support the provision of at least 800 new homes and 8.95 hectares of new employment space.

Public engagement

A public consultation exercise was undertaken in Spring 2016. 78% of respondents said that they agree with the proposals to improve the A259 in general, whereas 22% said that they generally do not support the proposed scheme. Support for the scheme was shown to be widespread throughout the local area.

Scheme cost

The dual carriageway works have an approved budget of £25.8m. This budget is jointly funded by the Coast to Capital Local Economic Partnership, West Sussex County Council and by private developer contributions.


Site preparation, including vegetation clearance at the Angmering end of the scheme was carried out early in 2019.

Further site clearance and Archaeological investigation work is taking place throughout August 2020. The main construction phase is currently scheduled to commence in September 2020 subject to the award of the construction phase contract. The works are expected to last for approximately 22 months.

WSCC will advertise any relevant dates on this web page and through a range of local media.

The scheme ties in with the Persimmon Homes works for the new Fitzalan link road and Lyminster bypass, which commenced in January 2020. These works will require a new junction east of Wick roundabout, where the new roads meet the A259. WSCC will work closely with Persimmon Homes to coordinate the various schemes.
