A27 Chichester Bypass

Highways England is undertaking a public consultation on options for improving the A27 Chichester Bypass. The Society has submitted the following comments:

These are the views of the South Downs Society in response to the current open consultation on the above. The Society, the national park society for the South Downs National Park, has nearly 2,000 members and its focus is the conservation and enhancement of the special qualities for which the park was designated. Our comments will reflect this focus.

The Society fully recognises the need to address the issues of congestion, unpredictable journey times and accidents on this stretch of the A27 and regards it as essential that any options progressed must have full regard to any implications for current and future traffic levels elsewhere along the road, including Worthing/Lancing and east of Lewes. We very much regret that the current exercise is road-based only and has been divorced from any real consideration of rail and bus transport: we regard this shift from integrated thinking on transport policy to be an unacceptable weakness in the approach.

That said, the Society welcomes the fact that no bypass options passing north of the city and close to the national park have been included in the consultation. If such options were to be resurrected the Society would strongly object.

We believe that any preferred option should be able to demonstrate that it can reduce congestion and unpredictable journey times on the Chichester bypass and bring about a commensurate reduction in traffic displaced by that congestion onto roads within the national park. It is essential that origin and destination survey data, mobile phone data and the results of any traffic modelling are shared with the public in a timely and user-friendly fashion in order to facilitate informed discussion about the potential implications of any changes to the bypass.

It is not this Society’s belief that the aim should be to create a 70 mph expressway. It would be our strong expectation that such a road would induce yet more traffic, increasing its contribution to climate change, potentially encouraging traffic to cross the national park to access it, diverting custom and thus the prospect of investment from the parallel, competing railway, and adding to the obvious traffic problems on the A27 further east.

The Society has attended the exhibitions of the options and taken the opportunity to discuss them with the staff present.

There are clearly local environmental implications attached to each of the options: these will rightly be raised by those directly concerned. As this Society’s remit is the impact on the national park, and much of the impact will be felt on the opposite, southern side of the city, we will restrict ourselves to one or two comments:

  • We note that a positive value, an “economic benefit”, is attached in the scheme evaluation to any reduction in journey time. From discussion with the staff at the exhibition it appears that no consideration has been given to whether a reduced journey time is an unmixed blessing, an absolute benefit: if, for example, car commuting from the south into the city centre may be achieved more quickly, will this not encourage more car traffic and is the city centre geared to accommodating it?
  • Views into the national park are as important as those within, or outwards from, the park. We would oppose the eastern end of the proposed link road forming part of option 2 where it passes beyond the B2201 towards Hunston. It would damage the iconic view of the cathedral and South Downs from the Chichester Canal at Poyntz Bridge, a view made famous in a painting by Turner, as well as destroying the tranquillity of the canal.


The consultation runs until 22 September. Here is a link to the Highways England consultation website:
