Wildlife and biodiversity net gain

The scheme will achieve a bio-diversity net gain (BNG) of at least 40% - more than four times the standard requirement. We want this project to go above and beyond to protect plants and wildlife.

The bypass will also introduce over 9km of new hedgerows to the landscape. This will provide bat commuting routes, emphasise existing field patterns, and highlight the area’s historical setting.

Through careful design, we aim to protect, create and enhance habitats via new woodland, grassland and wetlands. We will manage these areas to support protected and notable species of animals. This includes dormice, grass snakes, otters, badgers, birds and several species of bat.

We will also create

  • 23 hectares of new and improved grasslands
  • 3 hectares of new ponds and wetlands
  • 12 hectares of woodland

These will enhance the local landscape and wildlife, and create active travel links with easier access for cyclists and ramblers alike. In addition, we’re providing a further 7.7 hectares of bat mitigation space, which we consulted on in January 2023.

Carbon impacts

We’ve considered ‘whole life’ carbon in our design. This means we look for ways to cut carbon emissions during both bypass construction and once it’s open and used. By considering this at the start of the project, we can identify and prioritise carbon reduction in the design.

With this plan, we have exceeded our target of 33% carbon reduction. We have instead achieved a capital carbon reduction of 48% (compared to the baseline).

How we have reduced carbon emissions

There are many ways we are reducing carbon in construction. As a single carriageway, less material and less energy are needed to build the bypass. We will also look to use recycled materials where we can. We have also considered the alignment of the bypass, reducing the need for heavy earthworks used in construction.

Once the bypass opens, we have set a 40mph speed limit. This means that traffic will be free-flowing, a speed generating fewer emissions. The design of the bypass also includes a roundabout and junctions to ensure that traffic remains as free-flowing as possible.

In addition, the scheme will deliver miles of new walking, cycling, and horse-riding routes around the area. This will give local communities the option to further reduce their own carbon footprint via safer and more sustainable journeys.
