T-pylons – construction

In May 2020, we started work to build T-pylons between Bridgwater substation and a new cable sealing end compound (CSC) at Loxton, where it will join to the underground cables we’re building through the Mendip Hills.

We’ve appointed Balfour Beatty as the principal contractor for this stage of work and we expect it to be complete by late 2022.

Our first activity will be to build temporary road accesses and a temporary construction haul road that will allow us to move traffic off main roads directly into the construction areas.

Construction activity

Building the new overhead line will involve several different types of engineering activity. More information on how we build T-pylons can be found here.

We recognise that our construction activity impacts local communities. We are working with our contractor to limit that as much as possible.

Access and traffic management

We agreed a construction traffic management plan with the local authorities which sets out the roads our vehicles can use for construction work. We’re building temporary traffic access points and haul roads along the route of the cable that will allow us to move traffic off main roads directly into the construction areas.

When installing the accesses, haul roads and underground cables, we’ll need to manage traffic by temporarily closing some roads and controlling access at different times along parts of the cable route.

We will agree and coordinate all road closures and traffic management with the local highway authority. These will include:

  • Temporary traffic lights
  • Short term road closures (with diversions)
  • Restricted parking/suspensions.

Our contractors will put up advance notice signs to let local road users know of any traffic restrictions and road closures. Updates for the different areas can be found here.

Public footpaths

Where the new overhead line and the haul road cross public footpaths, we need to keep the area safe for the public and for our staff while we are working.

There will be temporary footpath closures with diversions for pedestrians at different times throughout the construction programme. Updates can be found here.

Working hours

Our agreed standard working hours are between 7am and 7pm Monday to Friday and 8am to 5pm on weekends.

Most work will be carried out on weekdays, although there may be occasions when we’ll need to work at weekends or outside the standard hours. These may include when we are working on a continuous process or if adverse weather or ground conditions cause delays, or to avoid traffic delays during the week, but there are restrictions to this.
