What we are doing
From 6 December 2024 to 10 January 2025, we will be constructing cross passage 20 near Carr Road, Northolt. During this time there will be periods of noisy works. To avoid overnight disturbance, we have agreed with the local authority to limit noisy activities Monday to Friday between 7am and 10pm, Saturdays 7am to 1pm and Sundays 10am to 3pm.
We will stop work for the Christmas period between 23 December 2024 and 1 January 2025.
Cross passages between the tunnels will allow HS2 passengers to get to a place of safety in an emergency, and are approximately 500 metres apart along the route.
Cross passage construction involves breaking into the side of the completed tunnel. This might generate some noise and vibration which may be heard or felt as ground borne noise in nearby buildings when transmitted through the ground to the surface. This cross passage is about 26 meters below ground, and about 60 metres from the closest property.
