We’re carrying out surveys along the route of a new overhead line from Sandford substation to Seabank substation (approximately 31.2 km).
The findings will help us to plan the final designs for the overhead line, the temporary road entrances and the haul roads needed to access the new pylon locations.
The surveys include:
- Ecological and topological studies which involve staff walking along the route. These have started and will continue until we start construction.
- Drainage tests – starting mid-March. We will spend about a day at each pylon and road access location.
- Trial boreholes to study ground conditions. These will involve using a mobile drilling rig.
- They are scheduled to start in the last week in February and will take place at several locations until mid-May.
Other preparations over the coming months will include carrying out ecological mitigation and clearing some vegetation and hedgerows, as well as erecting stock fencing along the route of the new overhead line.
Construction of the road accesses will start later in 2020 and we’ll start building the pylons in 2021. We’ll provide more information on the construction programme when it is available.
When we’re surveying the roads our contractor, Balfour Beatty, will need to manage the traffic to keep public and our workers safe. This will involve using temporary traffic lights or ‘stop/go’ boards. We’re sorry if this causes disruption to your journey.
