Learn more about the route of the line we're replacing with underground cable
The project will mitigate the visual impact of the existing section of overhead line near the villages of Martinstown and Winterbourne Abbas by replacing it with underground cabling.
We considered a range options for the underground route, with findings from our environmental and technical studies and feedback from stakeholders and the local community playing a vital role in shaping our plans.
The project involves:
- The replacement of the existing overhead line over a length of approximately 8.8km with underground cabling, including the removal of 22 pylons.
- Construction of two new sealing end compounds which are required to connect the new underground cables to the remaining existing overhead line, one to the north of the A35 and Winterbourne Abbas and the other to the south of Friar Waddon Hill.
The preferred route option has been designed to avoid properties, engineering constraints and known archaeology.
West Dorset District Council’s planning committee approved our planning application on 21 June 2018. Construction on the project began in summer 2019 and will take up to three years to complete (including the removal of the existing line).
