Mendip Cable – long term traffic management where our haul road crosses public highways

Our contractor, Balfour Beatty, is building a temporary haul road from our site compound off the A38 at Tarnock, through this part of the Mendip hills up to Towerhead on the A368.

The haul road allows us to move traffic off the A38 and A368 directly into construction areas, limiting our use of the local road network.

Where the haul road intersects with public highways, we need to make sure our vehicles can cross safely.

We will manage the crossings using traffic lights and warning signs. The lights will only stop traffic when our vehicles need to cross.

Sometimes when we are working on the public highway – to clear vegetation or carry out roadworks – we will need to use additional temporary traffic lights.

All traffic management is coordinated and agreed with the local Highway Authority, and our priority is safety for all road users. We are sorry if this causes a delay to your journey and thank you for your patience and understanding.

Road crossings

We need to cross six public highways in the Mendips:

  • A368 Sandford Road at Towerhead
  • Castle Hill
  • Mead Lane
  • Max Mill Lane
  • Webbington Road

A368 Sandford Road (Towerhead)

This is a busy, main road and is a main access to our construction haul road:

  • north towards Sandford substation site
  • south towards our compound at Tarnock

We have completed work to build road access on both sides of the carriage.

We have installed traffic lights. These will only operate to allow our construction vehicles to cross the road. They do not operate for vehicles turning in and out of site.

Castle Hill

This is a narrow, busy road and our construction vehicles will need to cross when travelling along our haul road.

We’ve completed work to build a road bellmouth on either side of the road and we are working with the local highways authority to agree the signage and traffic lights at the crossing point.

In the meantime, we are using temporary traffic lights which are manually operated when we need to cross the road.

Webbington Road

This is a narrow, busy road and our construction vehicles will need to cross when travelling along our haul road.

We’ve completed work to build a bellmouth on either side of the road and we have installed traffic lights. These will only operate when our construction vehicles need to cross the road.

Max Mill Lane

This is a narrow country lane.

We have carried out detailed archaeology surveys in this area and these have delayed some of work to build the crossing and haul road in this area

We are currently using temporary traffic lights when our vehicles need to cross here. We have installed permanent traffic lights and we expect to commission them when the archaeology surveys are complete.

The traffic lights will only operate when our construction vehicles need to cross the road.

Mead Lane

The lane is very narrow and single track with some passing places. We have tarmacked a short section at the crossing point and have completed work to build a bellmouth on either side of the lane.

We won’t use traffic lights here – instead it will be a ‘give way’, staffed crossing.
