Lyminster Bypass (North)

Details of the design and construction of a new bypass of the A284 Lyminster Road.

(Position at June 2019)

Background

The A284 is an important north-south link road from the A27 at Crossbush providing access to Littlehampton and to a lesser extent Bognor Regis.

Journey times and accessibility are affected by the Wick level crossing, which causes delays to traffic in both directions and can impact on the junction with the A259.

The bypass is proposed to improve safety and accessibility as well as contributing to regeneration in the Littlehampton and Bognor Regis areas.

The proposed scheme

West Sussex County Council is responsible for delivering the northern half of the Lyminster Bypass, which will alleviate traffic issues through Lyminster Village.

The bypass will link to the existing A284 from a point approximately 600m south of the A27 at Crossbush and join the privately developed section of the same proposed bypass at Toddington Nurseries.

The proposed bypass will be a 7.3m wide single dual carriageway with verge on one side and a shared footway/cycleway facility on the other. The footway/cycleway will connect to existing and proposed facilities along the southern half of the bypass and A259.

The existing public bridleway will be maintained with a Pegasus Crossing, provided to ensure the safety of equestrians, cyclists and pedestrians.

A new viaduct will be constructed over Black Ditch and its associated flood plain to ensure that there is no increase in flood risk. The existing culvert will be extended at Brookfield Stream. 

Surface water run-off from the proposed construction will discharge at greenfield run-off rates via the existing catchments.

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.

Benefits of the bypass

The benefits of constructing the proposed bypass encompass both local improvements and strategic objectives.

Locally, the bypass will alleviate traffic congestion through Wick and Lyminster improving safety and the reliability of journey times as well as decreasing pollution levels through the village.

More strategically, the bypass is linked to the provision of 1,260 new homes and 700 new jobs.

With the improved cyclist and pedestrian facilities, it is hoped that more people will be encouraged to undertake local trips on foot or by bike.

Public engagement

A public consultation exercise was undertaken in September 2014 with 61% of respondents in favour of the scheme, although it is noted that 31% did not support the scheme and the remaining 9% did not express an opinion.

Residents were also consulted on two options for the tie-in of the existing A284 to the proposed bypass with:

  • Option 1 (the most northerly option) selected following results of 51% in favour
  • Option 2 favoured by 11%, whilst 28% had no preference and 10% responded ‘don’t know’.

Scheme cost

The total estimated cost for the scheme is £17.8m and it is jointly funded by the Coast to Capital Local Economic Partnership, West Sussex County Council and private developer contributions.

Programme update

The scheme was granted planning on 26 March 2019 with the decision published on 9 May 2019 following the Secretary of State’s decision not to call-in the scheme. Subject to completion of the necessary land acquisition, we anticipate that construction will start in late spring 2020.
