Constructing the onshore cable route

Visibility splays

Visibility splays are locations where the Project is proposing to reduce the height of vegetation to improve overall road safety by ensuring construction vehicles leaving a site have good visibility before joining the local road network.

The proposed works associated with the visibility splays represent small scale changes in isolated areas along the onshore cable corridor.

There are 11 locations that have been identified following discussion with Essex County Council’s highways department and more detailed design work, including safety audits. These seek to allow safe access and egress for construction vehicles onto the public highway, allowing them to more clearly see other traffic approaching.

These visibility splays are shown on the overview map. They can be viewed in more detail on the interactive map link to interactive map and more information can be found in our PEIR Addendum.

The 11 locations of the visibility splays are as follows:

  • Fields south of Little Clacton Road
  • Thorpe Road
  • Sneating Hall Lane
  • Damant’s Farm Lane
  • B1414 / Landermere Road
  • Fields around Golden Lane
  • Fields north of Stones Green
  • South of the A120 / B1035 roundabout
  • Field east of Bentley Road
  • Payne’s Lane
  • Ardleigh Road

Temporary construction compounds

There will be a requirement to have TCCs in place in strategic locations along the onshore cable corridor. These will provide the Project with facilities to service the installation of approximately 24km of onshore cable, build the Project’s onshore substation, and store construction materials and plant.

The proposed locations of TCCs are shown on the overview map and listed below. They can be viewed in more detail on the interactive map and more information can be found in our PEIR Addendum.

As part of our ongoing work, we’ll carry out further surveys of proposed TCC locations and continue to liaise with Essex County Council with regard to their suitability and the safety of other road users.

TCCs may include:

  • Temporary fencing, the requirements of which will be determined by security factors and land use
  • Temporary site signage and potentially other site safety requirements
  • Temporary facilities for site personnel, although there will be no overnight accommodation on any of our sites
  • Storage of construction materials and plant
  • Temporary access to and from the site

Once we have finished using the TCCs we will, as far as practicable, reinstate the surface of the affected land to a condition similar to that which existed prior to entry, as evidenced by a pre-entry schedule of condition which dictates the condition in which land used by the Project must be left after completion.

The 12 locations of the Temporary construction compounds are as follows:

  • Landfall TCC off Short Lane
  • East of B1032 / Clacton Road
  • West of B1032 / Clacton Road
  • South of B1033 / Thorpe Road
  • North of B1035 / Tendring Road, south of Swan Road
  • North of B1035 / Thorpe Road, west of Swan Road
  • South of A120 off B1035 / Thorpe Road
  • North of A120, east of B1035 / Clacton Road
  • North of A120, west of B1035 / Clacton Road
  • East of Bentley Road
  • West of Bentley Road, north of onshore cable corridor
  • West of Bentley Road, south of onshore cable corridor
