What we are doing
We will be building reinforced concrete walls at the bottom of the main shaft, 23 metres below ground level.
Duration
9 February to 15 October 2026 – These works will be 24 hours a day, 5 days a week, Mondays to Fridays.
What to expect
You may notice staff on site, light from works within the shaft and mechanical noise from crane activities.
Additional Information
We will build reinforced concrete walls at the base of the main shaft. Materials will be lowered to the work area via the tower crane, during the day and at night. Hand tools, including drills, will be used to build the walls.
During the day and night shifts most of the works will be below ground. Above ground, you may notice the presence of staff around the site and mechanical noises from cranes as they support the site activities. You may also notice additional lighting on our site during the night. We will deliver concrete to site during the day.
HS2 is undergoing a comprehensive reset to ensure it can be built efficiently and for the lowest reasonable cost. This work is being carried out in stages and will be completed in 2026. We will provide you with updates on the reset and what this means for our plans to build the railway in your area.
