A27 Chichester

A package of improvements to reduce congestion on the A27 Chichester Bypass.

Progress report

The consultation on proposals for this scheme has now closed. We were pleased that so many people were able to have their say during the consultation. Many thanks to everyone who responded or who took the time to come along to one of our events. Your views will help us to ensure that that the improvements we take forward will deliver the benefits that the city deserves. The consultation documents are still available to view online on our A27 Chichester Bypass Improvements consultation page.

What next?

Consultation report

We are now analysing your feedback following the completion of the consultation on the A27 Chichester bypass improvement scheme. We are examining 4,900 questionnaires (both paper and online) as well as all of the comments we received during the 10 week consultation. We will share the results in the format of a final consultation report published on our consultation page. This report is expected to be published winter 2016/2017.

We will present our findings and reports along with our recommendation to the government who will make the final decision as to the preferred route. The preferred route is scheduled to be announced by late 2016.

In late 2017 you will be able to comment further on the preferred proposal. Before we submit our application to the Planning Inspectorate we will conduct a statutory consultation allowing the public and stakeholders a further say in our plans.

Why we need this scheme

The A27 Chichester Bypass has a poor safety record, being among the worst 10% of UK roads for casualties. (Source: the South Coast Central Route Strategy Evidence Report April 2014) The bypass and many local roads are often severely congested, especially during the seasonal peaks. The result is high traffic volumes on the city ring road and significant congestion at the four gates to the city centre during peak traffic periods. Emergency services are affected. Residential roads become 'rat runs' as traffic tries to avoid congestion hotspots. There are significant traffic delays at the railway level crossing and considerable congestion caused by the school run. It is anticipated that by 2025 this congestion will be intolerable and much of Chichester and the local road network will be gridlocked, unless traffic is managed more efficiently. To add to this there are only a limited number of safe opportunities for pedestrians and cyclists to cross the bypass. Several north/south bus routes cross the bypass, and suffer from the same congestion and delays as other traffic. This stops them from being an attractive alternative for car commuters. In the Road Investment Strategy, Highways England has committed to upgrading up to four of the junctions, the junctions being; Fishbourne Road (A259), Stockbridge Road (A286), Whyke (B2145) and Bognor Road (A259), Oving (B214) and Portfield (A258). The proposals aim to remove conflict and congestion at the bypass junctions and improve access to Chichester, the Manhood Peninsula and the wider Bognor Regis area, enabling other local transport improvements to be implemented.

Aims

This scheme aims to:
  • reduce congestion on the A27 Chichester Bypass
  • improve road safety
  • reduce adverse environmental impacts
  • improve journey time reliability
  • improve capacity and support the growth of regional economies
  • facilitate timely delivery of the scheme to enable provision of housing demand, in line with the Chichester Local Plan
  • improve regional connectivity
  • improve accessibility to areas with tourist activity

Wintering birds survey

As part of the ongoing environmental assessment into all five options we will be undertaking wintering bird surveys in an area to the south west of the existing bypass. This is known to be grazing land for Brent Geese from Chichester Harbour. The survey will also capture data on other birds from Chichester Harbour which are important to the designated conservation sites in the harbour.

A team of ecologists will carry out the fieldwork between November 2016 and February 2017and will involve ornithologists observing birds and recording their number and location. The surveys are required due to the proximity of Chichester Harbour to the existing bypass. They are therefore relevant to each of the five options which are being considered.

Environment impact

The area surrounding Chichester and the A27 is environmentally sensitive. It includes the Chichester Harbour Area of Outstanding Natural Beauty (site of national and international conservation importance) to the south west and South Downs National Park to the north. It also contains several watercourses and woodland areas of nature conservation importance.

We’re looking at the way each proposal could impact traffic, the environment, safety and future economic growth. We have:

  • set up various testing models to assess impacts and positive mitigations
  • conducted surveys
  • analysed the way business and housing might grow in the region

We’ve also been working with stakeholders to make sure our design options have minimal environmental impact, including:

  • Environment Agency
  • Natural England
  • Chichester Harbour Conservancy
  • South Downs National Park

Tourism and heritage

We are considering tourism and heritage in our proposals, especially the effect on the historic City of Chichester, the Manhood Peninsula and the surrounding built-up areas.

We are assessing how proposals could improve aspects of the environment for:

  • residents
  • tourists
  • countryside users
  • recreation
  • road users

To avoid or reduce adverse impact we’ll need to plan carefully at the preliminary design stage.

An important consideration is to preserve the views of Chichester Cathedral. We could use earth mounds, noise barriers and low noise surfacing and plant native trees and shrubs to mitigate visual and noise effects.

Wildlife

We’d manage construction and drainage systems provided to avoid contaminating watercourses and valuable habitats.

Air and noise

The traffic on the bypass has an impact on air quality and noise pollution. An Air Quality Management Area (AQMA) has been declared by Chichester District Council at Stockbridge Junction, while some junctions have been identified as priority locations by the Department for Environment Food and Rural Affairs (Defra), with noise issues that need to be addressed.
