The M5 motorway is an important corridor for regional and national transport in the UK, linking the South West with the Midlands and beyond. However, Junction 10 was previously a 'limited movement junction', allowing traffic to enter and exit only in certain directions. This caused congestion, delays, limited connectivity, and potential safety issues.
The M5 Junction 10 Improvement Scheme aimed to address these issues by improving the junction's layout and providing better access for vehicles traveling in all directions. More than just a road improvement project, the scheme will create opportunities for housing and employment and ensure that this critical section of the motorway continues to meet demand long into the future.
A key objective was to deliver a solution for M5 Junction 10 that aligns with the local environment, establishes biodiversity net gain, and meets climate change requirements.
As design consultant on behalf of Galliford Try, the Design and Build Contractor for the project, we focused on combining innovative design techniques with sustainability-focused strategies to create lasting environmental, social, and economic benefits.
Our approach to the M5 Junction 10 Improvement Scheme is projected to reduce carbon emissions by 30% compared to the project baseline. To date, we have avoided approximately 26,700 metric tons of potential CO2e emissions (22% reduction) compared to a conventional design.
Furthermore, the inclusion of sustainability principles has ensured meaningful benefits for the client, the local community, and the wider environment. The preliminary design phase alone has contributed to a 13% improvement in biodiversity net gain compared to the pre-existing environment.

As the project progresses, we remain committed to meeting and exceeding our sustainability targets, delivering meaningful benefits for our client, the local community, and the wider environment.
