A417 missing link
A landscape-led highways scheme that will deliver a safe and resilient free-flowing road while conserving and enhancing the special character of the Cotswolds National Landscape. Our scheme will improve the connection between two dual carriageway sections of the A417 at Brockworth and Cowley.
We're carrying out other maintenance work along the A419 and A417 through May and June 2025.

There are alternative parking options for visitors, including Crickley Hill. Bear in mind that you may need to pay at some of these car parks.
Plan of the Barrow Wake viewpoint closure.
Progress update
Our work on the project is progressing well. The civils work being carried out within the closures at Leckhampton Hill is on track to finish on time.
In other areas, we’re continuing to prepare for the Stockwell Farm bridge. Dry-stone walling continues at Stockwell and Cowley. Work is also continuing at the Gloucestershire Way Crossing location, following recent concrete pours for the central piers.
What’s happening at Crickley Hill and Shab Valley?
If you’ve travelled through Crickley Hill or Shab Valley recently, you may have spotted our teams progressing earthworks in the area.
That's because they’re using a rather impressive piece of machinery; a 90-tonne excavator with a 40-metre-high stitcher attachment which has been specially modified to carry out the task at hand.
Working with our supply chain partners Cofra, we’re installing over 40,000 vertical drains, some up to 20 metres into the ground. The drains will give residual water that’s beneath the surface a way out. By allowing it to escape, the drains will reduce the settlement period for earthworks from around 2-3 years to only 3-4 months, which significantly shortens the programme of construction for our project.
Vertical drains are traditionally used in flat areas of already free draining material such as sand or gravel. On this scheme, however, the drains are being installed on the hillside, so we’ve needed to create a series of small platforms which step up the 10% incline at Crickley Hill. This has been developed specifically for this project due to its unique topography.
Since we began these works in June this year, the team has installed over 8,000 drains, which is around 550 a day. If we continue at this rate, we expect it to be finished in December.
Out and about in the community
Summer site visits
This summer we’ve held five open days, giving members of the public the opportunity to tour our site and see how work is progressing across the scheme. Since the end of June, we’ve welcomed 324 people to site including local residents, businesses, community groups, councillors and MPs.
School engagement
We recently supported the Children’s Cake Bake in Bentham, raising money for local children in the area to subsidise summer holiday funds for days out.
Members of our team also volunteered at Coberley School, where we painted inside and out, renovated a vegetable garden, re-built a nature garden, and removed old unused equipment.
Shurdington Village fete
We also got involved in the Shurdington Village fete donating vouchers for a prize in the tombola. We hope everyone had a great time at the fete.
A417/A419 essential maintenance
We’re carrying out maintenance on the A417 and A419 separate from the A417 Missing Link scheme. This work is essential to keep the concrete carriageway safe and reliable for drivers. This work will be carried out in phases during weekends to minimise disruption. You can find out more on our South West maintenance webpage.

Progress through Summer
We're making good progress.
We've completed our advanced archaeological excavation phase. Oxford Cotswold Archaeology will remain on site monitoring groundworks into 2027.
We’ve completed foundation piling works at Shab Valley and have laid drainage mats at Grove Farm ready for further work.
We’ve also started the foundations for the Stockwell overpass and currently building the support columns for the Gloucestershire Way Crossing.
To do our work, we'll need to make some road closures. Please remember that closure details can change at short notice. For the most up-to-date information, please visit our daily closures page.
Barrow Wake car park closure

Project reaches next major milestone
We’re just about to start the next stage of major construction which will see earthworks start to excavate a new section of road from the Air Balloon roundabout. We’re doing this away from the existing route to minimise disruption as much as possible. You may have already seen the team carrying out earthworks which was for our new compound and car park area.
We’ll be storing and then repurposing all the materials removed from the landscape throughout the build, helping to minimise the scheme’s carbon footprint and the impact on the environment.

A look ahead to 2024
This January, we’ve been continuing with our preliminary works. As well as building a new site entrance close to the Air Balloon roundabout, we’ve been busy widening a section of carriageway on the A417 so that we can keep traffic moving more smoothly during the next phase of construction.
In April, we'll be ready to start building the new section of the A417. This section is to the south and east of the Air Balloon roundabout and is referred to as ‘offline’ as it is away from the existing road network.
Connecting Parishes
Improving connectivity doesn’t just apply to the road! Connecting Parishes is a project that National Highways is working on, together with Gloucestershire County Council and the Gloucestershire Local Access Forum, to improve connectivity and accessibility of the Public Rights of Way (PRoW) near the A417.
How is the project being funded?
This project has received Designated Funding from National Highways’ ‘Users and Communities’ fund, which aligns with the ‘Walkers, Cyclists and Horse Riders and Communities’ themes. The purpose of these funding streams is to build new infrastructure and enhance existing facilities to encourage sustainable, non-motorised forms of transport.
What is Connecting Parishes?
The Connecting Parishes project seeks to reconnect PRoW between neighbouring parishes and the Cotswolds Way, which were previously severed by the Strategic Road Network.
There will be a core focus on improving active travel, ensuring there are more accessible and safer active travel options which will enhance local connectivity for communities and allow more people to enjoy the Cotswolds National Landscape (formerly known as the Cotswolds Area of Outstanding Natural Beauty).
Working with Gloucestershire County Council, who are leading on delivering these projects, Connecting Parishes consists of 18 different sections of Public Rights of Way which will link into the Air Balloon Way, the Cotswold Way or other promoted routes.
You may have noticed some work has already started. If these works have impacted you, we’d like to thank you for your patience and understanding while we deliver this important project, which will offer many benefits to local people and visitors. We’ll share more updates with you and photos as the project progresses.

Air Balloon pub demolition complete
As you may have seen, demolition of the Air Balloon pub has now been completed. This was a necessary step to make way for the new A417 Missing Link road, which we will start to build early in the new year.
We understand how many of you value the history of the pub and, recognising that it was named after one of the first British balloon flights, we’re proposing to call a section of the repurposed A417, the Air Balloon Way.
We’re also planning to reuse as much of the building materials as possible and are exploring the possibility of using some of it to create installations and outdoor furniture for the local area that celebrate its cherished history. We already have a local carpenter lined up to make some benches that will eventually be located on the new and improved walking, cycling and horse riding network for all to enjoy.
We’ve started to clear vegetation in preparation for the next phase of construction. All vegetation clearance is being done sensitively, under the watchful eye of an independent arboricultural clerk of works. Site-wide inspections of trees and vegetation, ecological surveys and mitigation to protect trees and local bat populations were done prior to this work commencing. Wherever possible we will be replacing lost vegetation and trees, which will over time help screen the new road and create new habitats and habitat connections for native wildlife to flourish.

Seal of approval paves way for main construction
We’ve been working hard behind the scenes with local authorities and statutory bodies to ensure that planning conditions (requirements), as set out in our Development Consent Order, are met and signed-off (discharged) by the Secretary of State for Transport ahead of main construction.
A key milestone for the project, this task has now been completed and means we can start the main build in early 2024.
As we move towards this next phase you will start to see vegetation clearance along the route, which is being carried out under the watchful eye of a specialist clerk of works.
Secretary of State speaks about the scheme
In this short video, Rt Hon Mark Harper MP talks about the A417 Missing Link project during his recent visit to site. The Secretary of State is joined by Sir Geoffrey Clifton-Brown MP, CEO National Highways Nick Harris, Project Director Kevin Jones and Environmental Laad Kris Atkins.
What’s happening next?
Take a moment to watch this new animation video which explains how we are phasing construction of the A417 Missing Link.
Success as project secures prestigious NIPA award
We’re delighted to share that the A417 Missing Link project has been named winner of the National Infrastructure Planning Association (NIPA) Infrastructure Award 2023. The award recognises best practice for planning, design, development and delivery of Nationally Significant Infrastructure Projects. Commendations were given for “genuinely listening to stakeholders and changing design accordingly”.
The success of this project, through preliminary design, planning and Development Consent, has only been possible thanks to our stakeholders and the collaborative relationships we have with you.
Our shared goal has been to deliver much needed improvements to tackle the long-standing congestion and safety issues on this road, whilst conserving and enhancing the special character of the Cotswolds Area of Outstanding Natural Beauty.
A huge thank you goes to the local MPs, Cotswolds National Landscape, National Trust, Gloucestershire Wildlife Trust, our colleagues at Gloucestershire County Council, Cotswold District Council, Tewkesbury Borough Council, landowners and local communities. Every one of our stakeholders and partners has been key to shaping the scheme and its landscape-led vision.
We will continue to engage, keep you informed and ask for your support as we move through the construction phase.

Supporting UK bat species along the A417 Missing Link
Converting a World War II bunker for wildlife is just one of the innovative measures National Highways is taking to help support UK species of bats that have made their home in Gloucestershire.
The converted structure will be home to the Lesser Horseshoe, Brown Long Eared and other species of bats.
National Highways is also installing bat boxes in suitable habitat across the scheme, which although not obvious to passing motorists, provide vital homes for the bats.
In addition, ecologists will utilise a widely used and accepted tree aging technique for young trees and create roosts that mimics crevices only found on older more mature trees.
Three other bat structures will also be created as part of the scheme, and we will plant trees, hedges, woodland and grasslands to improve their foraging habitats.
To ensure local bat populations are properly supported during the build, we’ve got a team of Ecologists on site at all times to ensure these mitigation measures are implemented correctly.
Work on the scheme goes beyond bats though, with ecologists continuing to relocate reptiles away from construction areas including baby common lizards, slow worms, Roman snails and adders.

Preparatory work well under way
For those living locally or using the A417, you will have noticed lots of activity going on near the Air Balloon roundabout and Fly-up 417 Bike Park. You will have also noticed that we’ve set-up several small site offices, which include welfare facilities for the ecologists and archaeologists working on site.
All of this activity is part of the preparatory work we are doing ahead of construction in the autumn.
Our team of archaeologists are currently working at six locations in the area, and since the end of February, have removed approximately 8000 cubic metres of soil in their search for historical features and artefacts that can tell us more about the area and the people that once lived there.
We’ve also got ecologists on site who have been prepping archaeological research areas before work starts, for example putting up retile fencing to keep them away from work areas, checking for ground nesting birds and installing kite hawks to discourage skylarks from landing on site. These measures are ensuring local wildlife is protected.
Birdlip and the surrounding area is rich in history: the existing A417 largely follows the former Roman road between Cirencester and Gloucester and Birdlip itself is a historical Roman settlement. Picture shows topsoil being stripped from archaeological research areas.

Scheme gets the go-ahead
We’re delighted that Transport Minister Huw Merriman MP has today approved this landscape-led highways scheme that will deliver a safe and resilient free-flowing road while conserving and enhancing the special character of the Cotswolds Area of Outstanding Natural Beauty.
We would like to thank everyone who has provided feedback and helped shape this vital scheme, which will improve the connection between two dual carriageway sections of the A417 at Brockworth and Cowley, and links between the M4 and M5, making it safer and reducing traffic congestion and the knock-on effect of rat running in local villages.
The Minster’s long-awaited decision means we can now take action to improve this much needed stretch of road. Our Chief Executive, Nick Harris welcomes the news and explains what it means for local people.
To help you visualise the new road, see our latest fly-through animation.
We now enter a six-week judicial review period, but we will continue to work closely with our stakeholders and move this project forward during this time.
You can view the official decision letter, granting the scheme approval, on the Planning Inspectorate's website.

School pupils dig visit from National Highways staff
Our project team and representatives from Cotswold Archaeology took time out to visit Birdlip Primary School, where year 3 and 4 pupils got the chance to chat to the team about their jobs, plans to improve journeys between Brockworth bypass and Cowley roundabout and see what finds have been dug up along the route, which used to be the home to Romans.
One item discussed was an almost 2,000-year-old figurine depicting Cupid, the Roman God of love, which was discovered along with a bow-shaped brooch, and a Roman or early Saxon skeleton.
The items were found along the proposed 3.4 mile stretch of the new A417 Missing Link route and go some way to showing what life in the area was like thousands of years ago.
The Cupid figurine is a rare find, with less than 50 known in the UK, and is one of only three that have been found as part of an archaeological dig as opposed to by metal detectorists.
Made of solid bronze with wings and holding a flaming torch, the figurine was discovered in a deposit of charcoal, suggesting it could be an offering to the Gods.
Andrew Milner, Executive Head Teacher from Birdlip Primary School, said: “This was a wonderful opportunity to study the A417 Missing Link in depth. The children engaged with the archaeology to find out exactly what came before the road and then where the new road will go and how it will look. The team took the time to answer all the questions fully, in a way that was relevant to the children and the staff who turned up.”

Development Consent Order application accepted for examination
We are pleased to confirm that our proposals for the A417 Missing Link have been accepted by the Planning Inspectorate for formal examination.
This signifies a huge step towards delivering a landscape-led highways scheme that will provide a safe and resilient free-flowing road while conserving and enhancing where possible the special character of the Cotswolds Area of Outstanding Natural Beauty.
Thank you to everyone who has supported us getting to this point, providing your feedback to help us shape the scheme.
Next steps
The Planning Inspectorate will now examine the Development Consent Order (DCO) application through written representation and public hearings. They will then review all the evidence and make a recommendation to the Secretary of State for Transport, who has the final decision on whether the scheme should go ahead.
The examination and decision-making process will take over a year. You can find our more information about this process and how to get involved on the Planning Inspectorate’s website.

Overview
The A417/A419 provides an important route between Gloucester and Swindon that helps connect the Midlands/North to the South of England. It's an alternative to the M5/M4 route via Bristol. The Missing Link itself is a three-mile stretch of single-lane carriageway on the A417 between the Brockworth bypass and Cowley Roundabout in Gloucestershire.
The Missing Link causes many problems for road users and those who live or work in the area. Congestion can be frequent and unpredictable, so some motorists divert onto local roads to avoid tailbacks. This causes difficulties for neighbouring communities and local roads that were not built to accommodate so much traffic. Poor visibility and other factors also mean that accidents, many of which are serious, occur frequently along this section of road.
We’re improving the A417 with a scheme that includes:
- 4 miles of new dual carriageway connecting the existing A417 Brockworth bypass with the existing A417 dual carriageway south of Cowley
- a section to the west of the existing Air Balloon roundabout that will follow the existing A417 corridor. However, the section to the south and east of the Air Balloon roundabout will be offline, away from the existing road corridor
- a new junction at Shab Hill, providing a link from the A417 to the A436 towards Oxford and into Birdlip
- a new junction near Cowley, to replace the existing Cowley Roundabout
- the existing A417 between the Air Balloon roundabout and the Cowley Roundabout is being repurposed. We are converting some lengths of this existing road into a route for walkers, cyclists and horse riders, while retaining other sections to maintain local access for residents.

Next steps
We’re now in our offline construction phase of the scheme. This means that we're mainly working away from the existing road network.
The earthworks we've carried out in 2024 have allowed us to lay the foundations of the new bridges. We've also started piling works at numerous areas. Piling means using a specialist drilling rig to install foundations, posts and walls.
We’ve also started on Cowley junction, where we're building a new section of the A417. This is why we've introduced the Cowley Roundabout contraflow system that will be in place until 2027.
Upcoming milestones include:
- starting work on the Stockwell overbridge
- continuing work on seven kilometres of new Cotswold drystone walling. This wall will minimise the visual impact of the road and reduce noise
As we work, we’re monitoring wildlife in the area, including bats, birds, reptiles and badgers.
Our scheme is due to open for traffic in Spring 2027. However, we'll be finishing planting and landscaping up to the end of 2027.
We'll update this page as work continues.
Benefits
Our scheme to improve the A417 Missing Link will bring significant benefits to the local area. Before we began construction, we spoke to residents, local businesses and political leaders to find out the problems they face and how our scheme could benefit the south west.
Our scheme has four key objectives:
Transport and safety
Reducing delays, creating a free-flowing road network and improving safety along this stretch of the A417
Environment and heritage
Reducing the impact on the landscape, natural and historic environment of the Cotswolds. Where possible, enhancing the surrounding environment
Community and access
Reducing queuing traffic and pollution. Improving access for local people to the strategic road network. Supporting residents and visitors’ enjoyment to the countryside
Economic growth
Helping boost growth and prosperity by making journeys more reliable and improving connectivity.

Documents
Development Consent Order documents
The Development Consent Order (DCO) process was established by the Planning Act 2008 and is used for certain large and complex schemes (including highway improvements) that have been designated as a Nationally Significant Infrastructure Project (NSIP) by the Government.
The Secretary of State for Transport granted development consent for the A417 Missing Link Development Consent Order (DCO) on 16 November 2022. Links to key DCO documentation can be found below:
- Examining Authority’s report and recommendations to the Secretary of State for Transport
- Secretary of State for Transport’s decision letter and statement of reasons
- DCO as made by the Secretary of State for Transport
The made DCO is Statutory Instrument 2022 No. 1248 and is available to view at legislation.gov.uk.
Development Consent Order – Requirements Register
Requirements are conditions that have been included in the DCO, these control how the project must be implemented (constructed and maintained). Implementing the DCO in accordance with these conditions involves completing approval processes that have been defined in the DCO. These processes are referred to here and in the DCO as “discharging” the requirements.
This Requirements Register is a live document and will be updated as the process to discharge the requirements progresses.
The latest version will always be published below:
