A20 Coldharbour Roundabout Improvement Scheme Update

Project Update

The work on the project is progressing well.

Over the past month:

  • the central island of the new roundabout is nearly complete. All kerbs have been installed, drainage works complete and topsoiling is underway ahead of seeding;
  • asphalt placement is underway during night closures. Final surface course will be placed at a later stage of the scheme;
  • work on all of the island approaches to the roundabout is underway;
  • topsoil has been applied to various areas of the project in preparation for landscaping works to start; the old carriageway has been removed from the roundabout;
  • kerbs have been installed.

The full overnight closure (8pm-6am) started on 22 July and will continue until 10 August. The diversion on the A20 eastbound to ensure worker and road user safety remains in place.

Forthcoming Works

During August the following works are planned:

  • Completion of the maintenance track on the new roundabout.
  • Continuing work on the Eastern Widening on Coldharbour Lane, including footpath construction, drainage installation and kerbs.
  • Construction of the eastern island.
  • Start of landscaping works, including grass seeding. Tree planting will take place from November.

The lane closure on the western arm of the roundabout for UKPN to install a cable was implemented on 29 July and will be in place for 3-4 weeks. This lane closure is in place 24 hours a day.

The full overnight closure of the roundabout has now ended. The next full closure is planned for October. Once confirmed the dates and diversions will be displayed via electronic signage boards on all approaches to the roundabout and will also be on the project website www.coldharbourroundabout.co.uk

Regular adjustments to the traffic management will also be made.
