A27 Arundel Bypass Supplementary Consultation November 2022

Closed 16 Dec 2022

Opened 16 Nov 2022


From 11 January to 8 March 2022, National Highways held a statutory consultation on plans to improve the A27 by building a bypass around Arundel. 

We received thousands of responses to the statutory consultation and as a result of your feedback, as well as our ongoing design work, we are proposing some changes to the design of ‘the Scheme’.

We are now seeking your views on these changes in this supplementary consultation however, you only need to take part in this consultation if you have something additional to add, in light of the new information that’s being shared.

Why your views matter

We want to hear your thoughts on the suggested changes we’ve made since our last public consultation. Your feedback to this supplementary consultation will help us to continue to develop the preliminary design.

We are seeking your views on the work we have done to tackle a predicted rise in traffic along The Street in Walberton, which was shown at our earlier statutory consultation. We have reduced the number of additional car journeys along the eastern section of The Street in Walberton to an increase of 100 cars per day, compared to the increase  of 1,300 cars per day which was shown previously. This reduced number of journeys results from changes to the design presented at our Statutory Consultation.

We are providing an update on proposals for the Avisford Park Golf Club, proposals to mitigate our impacts on bats and new proposals for Crossbush Junction.

We also clarify information about the residential property that would be removed on Binsted Lane and provide additional detail on Yapton Lane.

To help you provide your feedback, we're making information available in lots of different ways:

Environmental Assessments

Our updated proposals have been designed to minimise environmental impacts whilst seeking to protect and enhance the quality of the surrounding environment through its design.

The scheme will continue to be assessed through the ongoing Environmental Impact Assessment process.  To date, our assessments have compared our original proposals presented in the statutory consultation with the new proposals presented in our Supplementary Consultation brochure and the environmental effects remain unchanged from those previously reported in January 2022.  As we move from preliminary to detailed design, environmental assessments will be refined before we submit a planning application to the Planning Inspectorate.

For more information regarding our environmental assessments, please refer to our Supplementary Consultation brochure. Alternatively, you can access previously published environmental related information from our earlier 2022 Statutory Consultation in the Related Documents section, including our Preliminary Environmental Information Report Non Technical Summary

What happens next? 

This scheme is classified as a Nationally Significant Infrastructure Project (NSIP) under the Planning Act 2008Because of its national significance, the scheme needs a Development Consent Order (DCO).

Following this consultation, we will carefully consider all comments received before submitting our DCO application. If the application is accepted by the Planning Inspectorate, there will then be an examination of the application in which the public can participate. The examination period will take a maximum of six months and The Planning Inspectorate then has three months to make a recommendation to the Secretary of State for Transport, who then has a further three months to make a final decision.

More information about the DCO process can be found on the Planning Inspectorate’s website here.

The DCO process is also explained below in our short animation below or you can read our Development Consent Order Leaflet to learn more about the planning process we follow.
