Roads to close as part of National Grid’s �50m Norwich to Fenland power line improvements

ROADS will be closed next month as part of a �50million power line upgrade by National Grid between Norwich and Fenland.

The eight-month project is rewiring the 52-mile high-voltage line between Norwich and Walpole, near Wisbech.

Engineers are renewing the conductors (wires) and fittings and carrying out strengthening work on some of the 224 pylons that carry the wires.

Project manager Simon Chandler said: “This work will help to ensure that our electricity supply continues to serve us safely, reliably and efficiently for decades to come, securing our energy supply for future generations.

“We apologise for any inconvenience caused, but the road and lane closures are essential for the safety of the public and our workforce. We will make every effort to complete the work as safely, quickly and efficiently as possible.”

The 400,000 volt power line was built in the early 1960s and now needs refurbishing. The work will enable National Grid to increase the capacity of the line and the network in East Anglia to secure future energy supplies.

The project is being carried out by National Grid, leading an electricity alliance with Balfour Beatty.
