St Peter's Way closures
Roundabout north-east section closures
The north-eastern section of St Peter’s Way Roundabout and St Peter’s Way eastbound carriageway towards the M25 will be closed from:
- Saturday 31 January 8pm to 5am
- Sunday 1 February 8pm to 5am
During the closures, a diversion will be in place via Guildford Road Northbound, Bell Bridge Road, A317, Chertsey Road, and St Peter’s Way westbound.
Eastbound closures
St Peter's Way eastbound will be closed overnight for five nights to carry out surfacing. Closures will be in place from 8pm to 5am each night from Monday 2 February to Saturday 7 February. During this closure, a signed diversion will be in place via Guildford Road Northbound, Bell Bridge Road, the A317, Chertsey Road and St Peter's Way.
Guildford Road closures
In order to continue enabling works and vegetation clearance at the Ottershaw roundabout, we need to close Guildford Road between Ottershaw and St Peter's roundabout from Thursday 29 January, 8pm to 5am, for two nights.
During the closure, a diversion for northbound traffic will be in place via Addlestone and Chertsey using Murray Road, Spinney Hill, Church Road, Chertsey Road and St Peter’s Way. The same diversion route will be in place for southbound traffic vice versa.
Cadent Gas works
Following the recent water-ingress incident on Guildford Road, Cadent Gas are carrying out essential upgrades to the pipes on Guildford Road. In order to carry out the works, they have installed temporary traffic lights on Guildford Road, from Bittams Lane to Salesian School. Works started on Monday 19 January 2026, and are expected to complete by 24 April 2026.
To minimise disruption, we’re working together closely with Cadent Gas to coordinate our A320 improvement works, sharing road space where possible. For information about the gas works, please visit the
Ongoing works
Ottershaw preparation works
Works currently in progress at St Peters roundabout are expected be completed soon and we are now preparing to move to the next working location, which is Ottershaw. Planned improvements to be undertaken in Ottershaw will include:
- Provision of a new and improved Ottershaw roundabout with greater circulatory capacity with widened approaches and exits providing additional traffic lanes
- Flood reduction initiatives, including the construction of attenuation ponds and shallow swales* Provision of shared-use pavements/cycle paths
- Improved lighting for all road users and provision of safe crossing facilities for pedestrians and cyclists
Some initial enabling works for the above are currently planned to commence from 19 January 2026 and will consist of early site and vegetation clearance, preliminary excavation work and establishment of a site compound.
Most of these works will be carried out on the verges, off carriageway. As work progresses, there may occasionally be the need for some on-carriageway traffic management measures. Where possible we aim to carry out on-carriageway works overnight, or during off-peak hours to minimise traffic disruption. We will mostly be working during the day, Monday to Friday, with out of hours work only undertaken if necessary to carry out certain key activities. While we will always aim to keep disruption to a minimum, the nature of our works may cause some disruption from time-to-time.
Murray Road car park
In order to carry out these works, we need to temporarily close the Murray Road car park. This is necessary to safely facilitate site clearance works immediately adjacent to the existing car park and build the satellite site compound. The car park closure will be in place from Monday 19 January 2026. Work to construct the new car park will begin immediately to enable the ongoing provision of parking in this area. We will provide progress updates and an expected reopening date as works progress. Answers to frequently asked questions regarding the car park can be found under the frequently asked questions on this page.
St Peter's Way works
Our contractor started phase one of the improvement works on 7 April 2025. There will be traffic management, including lane closures on St Peter's Way between the St Peter's Way roundabout and the M25 junction 11 roundabout. Lane closures are currently in place on St Peter's Way.
The traffic management will change as the works proceed, detailed information will be shared on our as work progresses.
Works during this phase will include:
- an extra lane constructed from the St Peter's Way roundabout towards the M25 on the A320 eastbound
- widening of the approach onto the St Peter's Way roundabout from the M25 on the A320 westbound
- widening of the northbound approach onto the St Peter's Way roundabout from Guildford Road
- widening of the footpath from the St Peter's Way roundabout towards St Peter's Hospital
- resurfacing of the entire St Peter's Way roundabout
A320 scheme update
Works to improve the busy stretch of road between Ottershaw and Chertsey began earlier this year, with works undertaken on St Peter's Way and outside Salesian school.
Following a review of the scheme's costs and available funding, it became clear that increasing construction costs means we're unable to deliver all of the improvements without exceeding the approved budget. Funding for the scheme was awarded in November 2020 by Homes England, which pre-dates several significant issues that have impacted the cost of all construction projects, including pandemic-related supply chain disruptions and rising material costs as a result of global conflicts.
As a result of these pressures, we will no longer be constructing three elements of the scheme that were outlined in the original proposal. These are:
- St Anne's roundabout
- Little Green Lane to St Peter's hospital roundabout
- St Peter's roundabout to Ottershaw roundabout
These changes have been agreed with Homes England, which supports the revised scope. The remaining six elements of the scheme are expected to be constructed as planned, ensuring we deliver improvements that provide the greatest benefit for local communities and road users. These elements are:
- St Peter’s Way roundabout
- Holloway Hill / Green Lane junction
- Ottershaw roundabout
- M25 junction 11
- St Peter’s Way east
- Guildford Road (outside Salesian School)
Scheme overview
ßÙßÇÂþ» has 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 support delivery of the .
The works will make sure all the junctions and 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, and improved access to public transport.
What's planned?
- Improvements to traffic lane facilities and full signalisation of St Peters Roundabout
- Provision of an additional, third traffic lane eastbound on St Peters Way East
- Provision of a new and improved Ottershaw roundabout with greater circulatory capacity with widened approaches and exits providing additional traffic lanes
- Improvements to the M25 junction 11 interchange, including full circulatory signalisation and widened northbound and southbound exit slip roads with new dedicated left turn lanes
- Provision of a new roundabout at the Holloway Hill/ Green Lane junction, with flood reduction initiatives, including the construction of attenuation ponds and shallow swales
- Provision of shared use footway/cycleways where possible
- Improvements to Guildford Road, near Salesian School, include installation of a dedicated drop-off layby / bus bays on the east side of Guildford Road along the front of the school
- Improved lighting for all road users and provision of safe crossing facilities for pedestrians and cyclists throughout the whole scheme

It is not permitted to park on double yellow lines under UK law.
General questions about the scheme
Why are you proposing changes to the A320?
The A320 North of Woking scheme is a partnership between ßÙßÇÂþ» as the highways authority, Runnymede Borough Council as the planning authority, and Homes England which is funding the work through its Housing Infrastructure Fund.
The scheme aims to increase the capacity of the local road network and improve sustainable transport infrastructure to support delivery of the .
What are the changes you are proposing?
The scheme comprises various road, pavement, public transport and cycle path improvements to junctions and the road along the A320 between Ottershaw and Chertsey.
Why is this necessary?
The local plan recognises that new housing is needed to meet demand, and it's important that the A320 as the key link road between the M25 and communities including Woking, Ottershaw and Chertsey is able to cope with increased numbers of vehicles.
It's also important to improve access to St Peter's Hospital using all modes of transport, but in particular emergency vehicles, as well as the need to support economic growth and to minimise disruption from roadworks.
When will construction start and how long will it last?
Preparation works started in autumn 2022, and included surveys and utility works. The main construction works started in March 2025.
Why is the traffic forecast only until 2030?
The scheme has been designed to accommodate the housing need identified in the Runnymede 2030 Local Plan. The proposed number of homes gave a prediction of motor vehicle numbers. As there is no current plan for housing need after 2030, we are unable to model what that would look like.
How are you protecting trees?
The scheme has been designed to maximise the retention of trees much as possible. We have designed in the retention of veteran trees and most mature trees wherever possible.
It will however be necessary to remove a small number of trees for safety reasons and to meet highway design standards. We will plant replacement new trees of varying size and species along or near to the route on a replacement like for like basis or greater. We also plan to secure additional land nearby for use as wildlife habitat to compensate for any habitat loss due to the scheme.
We have also already planted additional trees and grasses on additional land nearby as part of our Landscape and Ecological Management Plan (LEMP) to help compensate for any loss due to the scheme.
How are you minimising noise and air pollution?
The scheme has been developed to be free flowing which will reduce traffic congestion, reducing pollution as a result. Further assessments to understand the impacts of the scheme regarding noise are being undertaken as the design develops and mitigation measures will be considered if appropriate. The roundabouts at Ottershaw and Green Lane and Holloway Hill will include new landscaping and trees and shrubs to help protect the surrounding area from noise and air pollution.
Walking, cycling and public transport
What types of crossing points are you considering?
We are planning to include controlled crossings, including toucan crossings for pedestrian and cyclists. These are at all points close to significant desire lines where significant numbers of people need to cross a road. We will also provide uncontrolled crossing points where considered appropriate.
What improvements are you considering for pedestrians and cyclists?
We will be seeking to widen local footpaths and crossing points within the scheme area wherever possible. National Cycle Network route 223, a combined footpath and cycleway running alongside the A320, will be upgraded to a four-metre-wide footpath and cycleway running alongside the A320. Where possible pedestrian controlled crossings will be provided at points where this route crosses a road. We're also reviewing bus stop locations to ensure they are fully accessible and close to crossings.
Why is it important to improve pedestrian and cycling facilities?
Transport makes up 46% of ßÙßÇÂþ»'s carbon emissions, so encouraging people to use cleaner and greener transport will help bring us to our net zero carbon target. Improving walking and cycle routes can help people who cannot drive to travel more independently and safely. Improving the accessibility of footpaths for wheelchair users and providing cycleways suitable for adapted cycles, can help give people with disabilities more travel options.
How will you improve public transport?
Public transport routes will be maintained throughout the scheme. ßÙßÇÂþ» is looking to improve public transport within the scheme and the local area. This includes providing new bus stops and shelters, as well as improved passenger information facilities. Access to bus stops will be improved through localised crossing points and improved foot and cycle paths.
Ottershaw
Why has a bypass around Ottershaw not been considered?
There are no plans to build a new road on greenbelt to both the east and west of Ottershaw. Adequate funding is not available to deliver it.
Will the upgraded Ottershaw roundabout split the village in two?
The existing A320 currently affects connectivity in Ottershaw due to two key issues :
- Firstly, in respect of the large amount of slow moving and congested traffic along the A320. The improvements to the roundabout approaches through the construction of much improved stacking/queuing capacity, together with the increased circulatory capacity of the new roundabout itself will reduce the traffic congestion and aid through-flow particularly at peak times.
- Secondly, there is currently a lack of suitable pedestrian crossing points across the A320. The proposals will considerably address this issue with new controlled crossing points at key locations which in turn will improve the links of the east and west of the village.
By moving the roundabout to northwards and providing improved crossing points, the proposed design will move traffic away from the village and thus reduce its impact. Appropriate landscaping is proposed which will soften the appearance of the new junction and provide protection from air and noise pollution. We will engage further with Ottershaw residents before finalising the landscape design.
What are the reasons for the size, shape and location of the new Ottershaw roundabout?
The existing Ottershaw Roundabout struggles to cope with peak traffic from the four approach roads and the north bound segregated left turn lane from Chobham Road. The new roundabout is now designed to be as small as it can physically be whilst still dealing with the anticipated future traffic flow.
The roundabout also needs to be able to cope with a large number of Heavy Goods Vehicles (HGVs), within the constraints of a woodland and local buildings. These include 2 Chobham Road (a grade II listed building), Forge Oak (a locally listed building), Copse Lea Assisted Living Residence, Miller and Carter Steakhouse and Ottershaw Village Hall, as well as a substation, telephone exchange and ambulance station.
What are the plans for landscaping?
It is intended the landscaping will provide minimal screening to the rear of the car park, as well as the roundabout circulatory and connecting roads and junctions while trying to retain the existing character of the area. The plans include provision for the replacement of lost trees where possible. Landscaping plans can be found on the
What traffic calming is proposed?
A raised table has been included for the northern end of Brox Road to calm traffic.
Why are you not increasing capacity of Guildford Road North?
Our analysis has shown that traffic congestion is caused by the junctions. By improving the key junctions, we are improving the overall capacity along this stretch of the A320. This is verified though traffic microsimulation modelling.
Why does Brox Road not lead directly to the new roundabout?
Connecting Brox Road directly into the proposed roundabout will result in a significantly larger roundabout as it would need to accommodate a greater number of links. Furthermore, it was felt that such a direct roundabout link would encourage rat-running.
These factors would result in a roundabout with a significantly larger footprint that will have a greater impact on the village. Options that included a Brox Road connection into the roundabout were considered as part of the feasibility design but were discounted for the reasons above.
A number of alternative designs and suggestions have been offered, why are they not being used?
Unfortunately, the alternative options offered don't comply with the minimum highway design standards and they do not meet the future traffic capacity requirements in terms of growth and traffic movements.
What are the plans for Ottershaw car park?
We will replace the existing car park with a new, larger car park, in the same location. This car park will include a number of planned electric vehicle charging bays; these will be introduced following completion of the car park construction.
