Northern Powergrid has given an update on its plans to close the road between Richmond to Scotch Corner.
The road closures will start on Monday, February 7 and finish on Friday, April 22, however traffic lights will be in place until mid-May, the company says.
The work will take place in two phases.
The first phase will see work taking place between Scotch Corner and Scurragh Lane.
The company said: “From Monday 7 February until approximately Friday 18 March 2022, we will maintain full access to and from Skeeby for residents and buses (X26, X27 and school services).
“A marshal will be located at Skeeby substation to provide access to the village for residents and buses travelling from the South. For access to the North side of the village, residents and buses will be able to use Scurragh Lane, with a marshal in place at the junction of Scurragh Lane and the A6108.
“At night-time, road closure signs will be put in place at both ends of the closure and we will have a marshal on-site to support access for residents, late buses, gritting teams and emergency vehicles.”
Northern Powergrid said public and school bus services would operate as normal during this period.
The second phase will see work take place between Scurragh Lane and the Skeeby substation, which is between Skeeby and Richmond.
“From approximately Monday 21 March until Thursday 21 April 2022, the road will remain closed and information about access during this time will follow shortly.
“The road will reopen on Friday 22 April 2022. Between then and mid-May, we’ll be carrying out the last sections of our work using two-way traffic lights.”
Northern Powergrid has admitted its plan to close the A6108 will cause “significant inconvenience”.
However, the company said the closure was the only safe way for it to carry out work that it was required to do.
