Hannah More Road Closure – Hinkley Connection Project Update

The National Grid Hinkley Connection Project has affected the West End of Nailsea since early 2020 and has led to numerous road closures to make way for new underground cabling. The latest instalment of road closures involves Hannah More Road and the Queens Road junction.

Hannah More Road will be closed from Monday 22nd March for 10 days between 08:00 to 17:00. During this time, resurfacing and kerbing repairs will take place.

Queens Road may be affected by the closure at the Hannah More Road junction. Signs on Queens Road near this location indicate a closure of 2 days.

Hinkley Connection Project

Upon completion of the Hinkley Connection Project, the Hinkley C nuclear power station (Bridgwater), will be connected to Seabank, near Avonmouth. Over 6 million homes and businesses will use the cleaner energy, decreasing the UK’s carbon emissions.

The installation of 132,000 volt underground cables in the West End of Nailsea is part of the Nailsea and Portishead section. Here, overhead lines will be replaced with underground cables. To install the cables, temporary entrances and public road access must be created, as well as trenches dug.

Find out more about the project and its timeline on the National Grid Hinkley Connection Project website – there’s even a handy timeline and interactive map!

What Will Happen Next?

Once the underground cable installation is complete in Nailsea, work will begin on the installation of new T-pylons, situated farther from the town than existing lines. The new 400,000 volt overhead line is due to be installed over summer 2021.

Work has begun on the removal of the existing 132,000 volt lines that run close to residential properties.

The overall connection project is due to finish in 2025, however work in and around Nailsea should be completed by autumn 2021.
