A259 improvements

A259 Littlehampton improvements

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

(Position at March 2019)


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.

Eventually this will see improvements to the Tesco Bridge Road roundabout, 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, and improvements to Goring Crossways junction.

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

The current proposals are for the first phase of the project, the dual carriageway. Tesco Bridge Road and Goring Crossways junction improvements will come forward when local development funding is available.

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, segregated from the road by a verge along much of the route. Minor alterations will be made to the Body Shop roundabout to take into account the new, wider approach.

    The existing controlled crossing point will be upgraded to a Toucan crossing. A new Toucan crossing will be installed to the west of the Body Shop roundabout. Right turns across the carriageway, such as those at Oliver Acre and Cornfield Close, will be closed.

  2. From the Station Road 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. A new Toucan crossing will be provided near to Haskins. Right turns across the carriageway such as at Haskins, will be closed.

WSCC is working with contractor VolkerFitzpatrick to deliver the design and work phases. Volker Fitzpatrick is presently developing their construction plan. 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. This will be segregated from the road by grass verge. It is intended that this will improve access to local facilities for non-motorised vehicle users.

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 £14.8m. This budget is jointly funded by the Coast to Capital Local Economic Partnership, West Sussex County Council and private developer contributions.


The design was completed in 2018.

Site preparation, including vegetation clearance at the Angmering end of the scheme, started in February 2019 and will complete by mid March. The main works are expected to start in Summer 2019. The main works are expected to last for approximately 18 months.

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

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

The developer has reported that they will be starting site clearance works in March 2018, ahead of their likely commencement in Spring 2019, subject to contract and approvals.
