Didcot and surrounding area infrastructure improvements
About the improvements
The Didcot and surrounding areas major infrastructure scheme will provide vital transport infrastructure to reduce congestion and enable more reliable journey times, improve pedestrian and cycling connectivity, and support new employment sites and housing in and around Didcot.
The project includes four highway sections that incorporate improvements to existing roads, the construction of new roads, new walking and cycle routes, and will help to facilitate new and enhanced bus services.
Key benefits:
- 19km of walking and cycling paths to improve pedestrian and cycle connectivity for work and leisure trips
- 18 new bus stops to provide more sustainable travel options in and around Didcot
- Reduce congestion and improve air quality in surrounding villages and parishes
- Enable more jobs in the local area in new and existing employment sites
- Support expected housing growth in the local area
Compulsory purchase orders (CPOs) and side road orders (SROs)

What is happening when?
Enabling works
Enabling works have started on the Clifton Hampden Bypass and Didcot to Culham River Crossing sections.
The enabling works scheduled for completion between Autumn and Winter 2025 include:
- Erection of temporary fencing, including tree protection measures
- Archaeological investigations
- Vegetation and site clearance to facilitate archaeological activities
- Set up of main compounds, site offices, and welfare facilities
- Utility diversions
Most of the work will be carried out between 7.30am and 6pm, Monday through Friday, unless specified as overnight work.
There will be no work on Sundays or public holidays.
The majority of this work is taking place off the existing highway network; however, people may notice activity when travelling along the A4130, B4016, A415, and A4015, as well as from nearby public rights of way and the Thames footpath.
Public information events
We will be hosting five drop-in information events, during which members of the public can view the scheme's designs and learn about our emerging construction programme. The events will also provide an opportunity to ask questions and discuss any concerns with our project team.
No booking is required, and you can attend any event.

How it is being funded
The £332 million project is fully funded. Successful discussions with Government in 2022 and again in 2024, resulted in additional grants from Homes England.
In February 2022, approval was also given to underwrite up to £30m from Oxfordshire County Council’s capital budget, while Oxfordshire Local Enterprise Partnership contributed a £10m capital investment generated from Enterprise Zones’ business rates retention.
