from HS2
We are carrying out utilities works on the A40 to protect the main gas pipe below the A40 Western Avenue between Hanger Lane Gyratory and Gypsy Corner. We will be digging a number of trenches along the road to reach the depth of the main gas pipe. The existing metal gas pipe will be replaced with plastic.
Please note that these works were due to be completed on 17 November, but have now been extended to 10 December 2023. The reason for the extension is unexpected additional works.
