A30 Designated Funds

We’re using part of the Designated Funds to support projects close to the A30 in Cornwall

Over the past few years, we’ve been developing several projects along the A30 in Cornwall which look to use designated funding to improve the surroundings of our network. This work includes looking at improvements to the safety and integration of communities through several cycling projects.


We’ve also been exploring how we can enhance the visual landscape, support cultural heritage and improve the biodiversity of the surrounding area.  


We’ve carried out the design work and some construction for an environmental work programme along the A30 in Cornwall called ‘Keyn Glas’. As part of this programme, we worked closely with local stakeholders to identify opportunities to protect and enhance the landscape, water, soil, air, biodiversity, and the historic environment.

We were recently awarded the Best Practice: Stakeholder Engagement award from the Chartered Institute of Ecology and Environmental Management in recognition of this work. 

You can find an update on each of the projects below.

Green ribs

As part of our landscape projects, we’ve created some ‘green ribs’ which extend out from the A30. These aim to connect core habitat areas and achieve continuous landscape corridors.

This work included:

  • tree works (woodland creation, orchard creation and restoration, and veteran tree management)
  • planting of species rich grassland and wet meadow
  • restoring ponds and wet habitat
  • hedging (creation and restoration of Cornish hedge, thorny hedge planting, and hedgerow enhancement)

Tree planting at Goonwinnow

In Roads Period 1 we created three green ribs at the following locations:

  • Ladock to Gwills
  • Benny Mill to Boswiddle
  • Benhaven to Lambourne Mill

We are pleased to have received additional funding to further progress the green ribs. The Cornwall Wildlife Trust will restore and recreate 16.8 hectares of woodland, orchard, grassland and heathland around Ladock to Gwills and Benhaven to Lambourne Mill.

We’re also working in partnership with the Environment Agency who have provided co-funding on the green ribs projects, which will help to tackle biodiversity within the county by:

  • creating and enhancing habitat areas for wildlife
  • improving the quality, condition and connectivity of landscape features in Cornwall
  • mitigating severance impacts of the A30 by creating stronger habitat connections, safely channelling wildlife away from the road.

We’ve now completed the design work for the below projects. As part of our design work, we reviewed the design of each scheme against our funding criteria and analysed the benefits that the projects would provide to the public if constructed. Following this review, we decided which projects we could take forward to construction and which projects didn’t provide sufficient benefits. Unfortunately, we won’t be taking the below projects forward to construction.

Water quality projects:

  • Upper Tresillian river project
  • Brighton stream project 
  • Bolingey stream project 
  • Arrallas Ponds (some design work ongoing) 

Biodiversity habitat projects:

  • Newlyn Downs heathland enhancement and restoration 
  • Adapting mineshafts for bats 
  • Carnhot county wildlife site 
  • Habitat connections on the A39

Cultural heritage projects:

  • Chacewater townscape
  • Zelah streetscape
  • Wheal Busy
  • Chyverton Park
  • Landscape of Ancestors (Warren’s Barrow)

For some of these projects, we’ve progressed the designs sufficiently so that if another organisation had funding available, a suitable design would potentially be ready to build.  


Cycling, safety and integration (CSI)

We continue to work closely with Cornwall Council to deliver the Saints Trails cycle network. The network will build new dedicated lanes for walkers, cyclists and horse riders, safely connecting people to where they want to go. The trails will provide approximately 13km of off-road and on-road trails. They will help to address congestion and air quality issues, whilst also encouraging healthier lifestyle choices.

The cycle network is split into the following routes. Following a review with Cornwall Council there have been some changes to the original proposed routes. These will provide benefits to cyclists and walkers more quickly.

  • St Agnes to Threemilestone (via Chiverton Cross): making use of existing quiet lanes with enhanced safety features, this route will link with a new planned bridge crossing for cyclists, walkers and horse riders over the A30 at Chiverton Cross (part of a separate Cornwall Council project funded with EU money.) From Chiverton Cross an off-road cycle path will connect to new facilities proposed at Threemilestone.
  • Perranporth to Goonhavern : the reinstatement of a dismantled railway line as a multi-use trail for walkers, cyclists and horse-riders. The route starts in Perranporth and continues through to Cocks Village to Goonhavern

The Goonhavern section of this route has been completed and work has taken place to clear other sections ready for construction.
