 Public Rights of Way

As part of our construction planning, we're consulting with users of the Public Rights of Way tracks along the cable route, to ensure that any closures are communicated in a clear and helpful way. We've established a PRoW Liaison Group, and have been working with Parish Councils to raise awareness of the coming works.

If you would like to see how we're proposing to manage the temporary closures, please see the illustrations below. A detailed schedule of works will be shared before construction starts, and any closures will be detailed.

For more detailed information on proposed PRoW closures and diversions, please visit the PRoW page here.

If you would like to join the PRoW liaison group, please email rampion@eon.com with and expression of interest.

The two 400kV transformers were delivered to site in November and works continue with the installation of site equipment.
