OWAIRA ALERT! A320 ‘IMPROVMENTS’ through Ottershaw

You will be aware of the long running ideas coming from SCC for ‘improvements’ to the A320, including the ‘horrendous’ roundabout at the Otter! Surrey County Council (SCC) has launched a Web site and emailed many residents about the A320 Highways proposals. The web site is They are asking for the opinions of users of the A320.

Roundabout and Car Park

Two of the major concerns expressed by residents previously have been the scale of the proposed new roundabout system and the re-siting of the village carpark. The tone of SCC web publicity has changed since December 2020. At that time, the website contained the somewhat cheery news that the new roundabout would be of ‘conventional’ design – now it is stated it will be ‘relocated’. Secondly, in December 2020 SCC told us that the ‘Existing carpark would be retained’. Now they are just saying ‘Retention of a village carpark’. Very similar to the original 2018 Arcadis proposal?

Opinion then was that we do not want the village to be severed by a huge new roundabout system nor do we want the carpark moved further away from the village hall. We may need to restate that now.

A320 work is required to mitigate the effects of the increased traffic generation from new developments already approved in the Runnymede Local Plan for some 3000 new dwellings along with the significant additional growth in Woking and surrounding areas over the next 10 years.

Highways England are also planning major works on the M25 and particularly through Junction 11 at St Peters Way.


SCC and Runnymede BC have jointly been awarded £42million by the Government (HIF) to undertake the works on the A320, (excludes M25 works). Work must be finished by 2023/24. This must be done before much of the housing allocated in the RBC Local Plan is released to build. If the money is not utilised by then, it may be withdrawn and ‘lost’, and Runnymede will not be able to meet the delivery of new homes – as instructed by Government. SCC appears therefore to be reducing the scale of its plans for the A320, (incl the huge Otter Roundabout) to be sure to meet the cutoff.

What are we doing?

OWAIRA Committee members along with your local Councillors have been engaged with SCC extensively over the last three years seeking to influence design proposals. We feel that the representations are having some beneficial effect. SCC propose issuing new design ideas after receiving your feedback, possibly in May, with detailed engineering designs produced by Spring 2022 and works commencing that year.

Please complete this consultation by responding to SCC using the form on their website (and making full use of the ‘Comments’ box at the end) or by emailing the project team at

If you wish, please copy your responses to to enable OWAIRA to continue to represent the interests of all Ward Residents and businesses. Members of OWAIRA will be kept informed as matters progress and will be consulted. Please join! Thank you

Excerpts from latest update on the SCC website -

Making improvements to the A320 in Runnymede between Chertsey and Ottershaw

Surrey County Council and Runnymede Borough Council have been awarded £41.8 million by Homes England's Housing Infrastructure Fund to improve the A320.

The works will ensure there is extra capacity on the busy stretch of road between Chertsey and Ottershaw to unlock future housing sites allocated in the Borough’s recently adopted Local Plan.

The works will make sure all the junctions and link roads work well together to improve traffic flow. There will also be improvements for walkers and cyclists, including new crossing points and wider foot and cycle paths.

Upgrading the A320 will enable approximately 3,000 new homes to be built across 10 sites in this part of Runnymede – a key component of the Borough's recently approved Local Plan.

Have your say on plans for the A320

We would like your views on travelling along the A320 – how do you find the route and what could improve it?

We will listen to your feedback and use it to help shape our designs, which we'll share with you in the Spring. You will also have an opportunity to give your feedback on these emerging designs when they are published. This webpage will be open for comments until Sunday 14 March.

We are working on planned improvements to a number of road junctions, including the M25 junction 11 and associated link roads and these are expected to help address issues associated with expected increases in traffic over the next 10 years, as well as improving facilities for pedestrians and cyclists. It is planned for the works to be completed by 2024.
