A47 schemes judicial review Court of Appeal outcome – Dismissed
On 22 February, we received the outcome of the appeal against the Judicial Review Process for the three improvement schemes on the A47.
Three judges found that the Development Consent Orders (DCOs), previously granted by the Secretary of State for Transport, were properly assessed by the government for the cumulative effects of carbon, and will stand.
This means we can now begin work on developing our plans for the construction phase of the project and when we will be able to start work on the three schemes along the A47, improving customer journeys, enhancing safety and supporting economic growth in the region.
We will provide further updates on the progress of our plans and start of works in due course.

Update on the legal challenge
A legal case heard in July 2023 had challenged the decisions from the Secretary of State for Transport to grant development consent orders (DCOs) for this and two other A47 improvement schemes near Norwich. The High Court judge, Mrs Justice Thornton, dismissed the claimant’s argument.
However, on 18 October 2023, the Court of Appeal granted the claimant a right to have his appeal heard.
We have been advised that the one-day hearing will be held on 16 January 2024.
Allowing the appeal to be heard is disappointing, causing further delay to these schemes. This is a difficult turn of events for those of us who recognise and support the safety case to upgrade key stretches of this very busy road.
As we have done throughout this process, National Highways will continue to respect the decision of the court.
In the meantime, we are taking time to fully consider our next steps. This includes what work can continue at our sites to ensure the areas remain safe and with as little disruption and disturbance to those living nearby as possible.
The A47 Thickthorn junction scheme was already in a retendering process to ensure we deliver best value for our customers and stakeholders. This is going well, and we do not envisage any significant impacts or changes. The project team is currently conducting minor work, including environmental monitoring activity. Work is not expected to commence in earnest until the legal process is completed and the new supplier is on board.
We remain committed to delivering these plans, and confident that they will provide significant improvements to both safety and congestion on the A47, as well as helping to boost the regional economy.

Update on the A47 Norwich schemes
We have received notification that an appeal on the court’s decision to reject the claims in the judicial review of our three Norwich schemes has been submitted.
What does this mean?
The Court of Appeal must now decide whether to grant the claimant permission to appeal. National Highways will be taking all necessary steps to challenge the application.
Next steps
To avoid any further delays, we can continue to carry out early works, such as archaeology, compound set up and utility diversions, on the schemes while we await the court’s decision.
We stand by our plan to deliver these important schemes and remain confident they can deliver significant improvements to both safety and congestion on the A47, as well as providing a significant boost to the regional economy.

A47 Norwich schemes – outcome of judicial review
We have been informed by the High Court that the claims in the judicial review held on 10 to 11 May 2023 have been rejected, and found in favour of the Secretary of State for Transport.
The judicial review challenged the decisions made by the Secretary of State for Transport in granting development consent orders (DCO) to three A47 road improvement schemes near Norwich.The news means that the DCO decisions for these schemes still stand. Among the main grounds for the legal challenges was how cumulative carbon is assessed by the government at a national level. This has been fundamentally rejected by the High Court on all grounds.
We welcome the outcome, which means we can continue our work to deliver these much-needed schemes:
• New dual carriageway and junctions between A47 Blofield and North Burlingham
• New dual carriageway and junctions between A47 North Tuddenham and Easton
• Redevelopment of Thickthorn junction (where A11 meets the A47 south of Norwich)
Next steps
Work on these schemes has previously been limited while we were awaiting the outcome of the judicial review. Now that we have this clarity, we are working with our contractor to establish new construction timescales. We intend to start work on the three affected schemes as soon as possible.
Face-to-face public information events
Over the next few months, we’ll hold another round of face-to-face public information events. Come along to meet the team and hear about our construction plans at the following locations:
• Wednesday 26 July, 10am to 4pm at Norwich Camping and Leisure, 58 Yarmouth Road, Blofield, Norwich, NR13 4LQ
• Thursday 27 July, 10am to 4pm at Acle Coop, Norwich Road, Acle, Norwich, NR13 3BY

Update on the A47 legal challenges
A legal challenge has been made to the Secretary of State (SoS) for Transport's decision to grant Development Consent Order (DCO) for our three A47 schemes:
• A47 Blofield to North Burlingham
• A47 North Tuddenham to Easton
• A47/A11 Thickthorn junction
The challenge mainly focuses on the way cumulative carbon assessments were carried out, along with local carbon plans, bat licences and the completeness of the briefings given to the Ministers prior to the decisions.
On 14 December the High Court held an oral hearing for the claimant to put their arguments to a judge as to why the challenges should proceed to a judicial review. At this hearing the judge granted permission for a substantive hearing, mainly on the grounds of how cumulative carbon is assessed by government at a national level, so the case will now progress to a full judicial review.
A judicial review is the process of challenging the lawfulness of decisions made by public authorities, including central government, so this will now decide whether the SoS acted lawfully. The challenge to the A47 schemes is not on the schemes themselves, but to the process of approving the DCOs.
Delay to our schemes
This means we cannot start work as soon as we had originally planned on the three A47 schemes and have had to delay the improvements our customers have asked us for.
Our continued commitment
We stand by our plans and remain committed to investing almost half a billion pounds on a series of improvements to the A47 the people and businesses of East Anglia have told us they want. These will make the road safer, connect local communities and deliver a huge economic boost to the region.
Over the last three months we have held a series of public information events, attended by over 800 people, and the feedback from our stakeholders was positive towards our A47 schemes.
We will now work with the Department for Transport, ahead of the case being heard in full.More information

Development Consent Order given the green light
Today we welcomed the Secretary of State for Transport’s decision to grant us a planning application called a Development Consent Order (DCO), which allows us to proceed with our plans to improve the A47/A11 Thickthorn junction. You can view the decision letter here.
The scheme will:
- provide two new free-flowing connections with the A47 and A11 and re-route traffic away from the existing junction
- change the existing roundabout at the junction, providing an additional lane for traffic, improved traffic signals and pedestrian crossings
- construct a new road between Cantley Lane South and B1172 Norwich Road to allow continued access to the junction
- provide a new footbridge crossing the A47 between Cantley Lane South and Cantley Lane to accommodate walkers, cyclists, horse riders and other vulnerable users
The improvements will:
- reduce congestion, make journey times more reliable, and increase capacity
- improve road safety for motorists and for those living near the junction
- help the road cope better if there are vehicle collisions or breakdowns, and during road maintenance
- support regional housing and economic growth in Norwich and the surrounding areas
- protect the environment by minimising adverse impacts and, where possible, deliver benefits
- improve access roads for local communities
- provide a safer route for walkers, cyclist, horse riders and vulnerable users
The existing A47 has one of the highest recorded accident rates for an A road in the UK. Traffic modelling data from 2019 shows this section of the A47 is used by over 60,000 vehicles a day.
The scheme will improve road safety by reducing the number of accidents and consequently the number of casualties: over a 60-year timeframe, the scheme’s improvements could save up to 242 accidents and 26 killed or seriously injured (KSIs).

Archaeological work starts, November 2021
We're carrying out some survey work in the area from Monday 8 November to Friday 12 November. This is to understand the archaeology of the area where we are proposing to upgrade the road. This work will help us start to plan the work ahead of the next stage in the project. It is not the start of construction.
The work we will be doing includes digging 25 trial trenches, each up to 40 metres long, and 15 smaller, hand-dug pits so we can find archaeological remains or see if there are any heritage sites of interest and ensure they will not be disturbed by the proposed scheme when main work starts. You will see operatives at work to prepare these trenches, including operating diggers and heavy plant machinery, but this work is strictly to understand the archaeology of the area and ensure the proposed scheme cannot damage it.
Some of the surveys will take place on the road, so to ensure our workforce is safe during this time, we will need to make some lane and road closures. We apologise for any inconvenience these may cause.
Lane and road closures during this work:
- Three-way traffic lights on the B1172 from 8am to 4pm from Monday 8 to Wednesday 10 November.
- Closure of lane one (inside lane) of the A47 by the junction in both directions overnight, from 8pm to 6am, from Monday 8 to Wednesday 10 November.
- The closure of Cantley Lane South from 8am to 4pm from Thursday 11 to Friday 12 November.

Scheme update - July 2021
Planning Inspectorate acceptance of scheme submission
We are pleased to announce that our Development Consent Order Application was submitted to the Planning Inspectorate in March 2021 and was accepted in April 2021, allowing us to progress through to examination. The next steps in the process can be found on the Planning Inspectorate’s website.
The Section 56 Notice notifies the public that the A47/A11 Thickthorn Junction Development Consent Order application has been accepted for examination. View the Section 56 Notice.
Members of the public were able to register to participate in the examination, and provide a response to our application during the Relevant Representation period, which closed on Wednesday 7 July 2021 at 23:59.
Details of next steps for this scheme are available on the A11/A47 Thickthorn project web page on the Planning Inspectorate website.
Ground investigations and surveys
We are carrying out some important surveys and ground investigations work in the area until October 2021. These will give us a clearer picture of the condition of the existing road, as well as types of soils, rock types and the ground water levels where we are proposing to upgrade the road.
This work will help us start to plan the work safely and economically, ahead of the next stage in the project. However, this is not the start of construction.
You can expect to see survey vehicles and equipment in operation close to the Thickthorn junction, although some of the surveys will take place on private property such as farms and surrounding land.
Types of surveys we’ll be carrying out:
- Topographical surveys which are aerial surveys to understand the existing levels of the area
- Utility trial holes to identify the precise location of existing services and utilities
- Ground investigations to understand the existing environment and subsoil elements in order to ensure the chosen design is a workable solution
- Road surveys which are a series of tests on the existing road to determine condition, depth and materials
- Asset condition surveys to understand the condition of existing highways assets, for example bridges
Where survey work is due to take place next to residential properties, we will write to those residents in advance and let them know what is happening and when. We have advised landowners where we need access to their land. Some of the surveys will take place on the road, so we will need to make some lane and road closures to ensure our workforce is safe during the work.
Survey work will mainly take place on weekdays during the dates shown in the table below. Follow our regional Twitter feed @HighwaysEAST and Facebook page @HighwaysEAST for the latest updates.

Consultation now closed
The statutory consultation on our proposal to upgrade the A47/A11 Thickthorn junction has now closed.
We have been reviewing and considering the feedback you've provided through the consultation. Where appropriate, we are using the feedback to make further refinements to our proposed design and development of mitigation measures.
Whilst further design refinements may continue during our conversations with key stakeholders and as further survey results become available, we have issued a project update and a refined junction design.
We expect to submit our application for development consent early next year (2021). The application will include a consultation report which will feature a summary of responses and will describe which suggestions we were able to incorporate. This will demonstrate how we have listened to feedback.
Our application for development consent will be available to the public on the Planning Inspectorate’s website after its submission.
Please watch our video for more information on the Development Consent process.

Surveys taking place from Summer 2020
We will be undertaking important surveys and archaeological trial trenching from this summer (2020). You can expect to see survey vehicles and equipment in operation close to Thickthorn junction, but please note that this is not the start of any construction work.
The investigations will help us better understand any local archaeology and give us information on how we may need to adjust the junction layouts. The surveys are critical for ensuring that we limit any possible impacts by fully recording all archaeological sites. The results of the surveys will be reported in our Environmental Statement and are a normal part of the development consent process.
This type of early survey work will help us to avoid any unexpected surprises and unnecessary delays once construction starts. It also means we can develop a plan for mitigation work and construction to coincide on site once the project is given the go-ahead.
Project information
The A47/A11 Thickthorn junction near Norwich is important for commuter, business and commercial traffic, on both short and long-distance journeys.
Around 3,000 new residential dwellings are potentially planned near the junction, along with commercial business units. This local growth is likely to increase congestion on the junction and the roads that feed into it.
The project will help relieve congestion at the Thickthorn junction by providing two new free-flowing slip roads that will connect the A47 with the A11. The new slip roads will re-route traffic away from the junction and flow it under new underpasses.
We’ll also remove the existing footbridge over the A47 and provide a new footbridge for walkers, cyclists and horse riders.
Revised layout
Our revised layout that we intend to submit for planning approval includes:
- a single-lane free-flowing link road connecting the A11 northbound to A47 eastbound via two underpasses (under the A11 and A47 respectively)
- improvements to the junction:
- widening the existing slip road on the A47 westbound and building a dedicated left-hand free flow lane to the A11 southbound.
- widening the southern section of the roundabout from three lanes to four
- new traffic lights on the approach to / from the junction with the B1172 Norwich Road
- new road surface, new road signs and road markings throughout the junction.
- removal of the Cantley Lane South direct connections between the A11 and A47 exit slip roads
- a new link road connecting Cantley Lane South with the B1172 Norwich Road to the north and construction of two new bridges. The new link road it will have a 40mph speed limit
- from the Thickthorn junction to Hethersett, a 40mph speed limit on the B1172 Norwich Road and a new junction connecting to Cantley Lane Link road.
- a 30mph speed limit on Cantley Lane South
- a new junction connecting Cantley Lane South to Cantley Lane link road
- the existing Cantley Lane stream and access track will be realigned and one new stream culvert constructed
- a new footbridge over the A47 for walkers, cyclists and horse riders approximately 45m east of the existing footbridge (which will be demolished). The footbridge will have higher railings to help improve safety for horse riders
- paths for walking and cycling proposed along the new Cantley Lane link road giving access to local amenities and links to other recreational routes
- access to the Park and Ride from the Cantley Lane link road for walkers and cyclists
These improvements to the junction near Norwich aim to:
- improve road safety for motorists and for those living near the junction
- reduce congestion, make journey times more reliable, and increase capacity for future traffic growth
- Help the road cope better if there are vehicle collisions or breakdowns, and during road maintenance
- Help support regional housing and economic growth in Norwich and the surrounding areas
- help protect the environment by minimising adverse impacts and, where possible, deliver benefits
- consider local communities and their access to the roads
- provide a safer route between communities for cyclists, walkers, horse riders and other non-motorist groups
