What we are doing
From 14 August to 26 September 2024, we will be constructing a cross passage near North Acton Allotments and Western Avenue. Within this time there will be periods of noisy works.
To avoid overnight disturbance, we have agreed with the local authority to limit noisy activities to between 7am and 10pm Monday to Sunday.
Cross passages between the tunnels allow HS2 passengers to get to a place of safety in an emergency and are approximately 500 metres apart along the route. This cross passage is approximately 13 metres deep and 20 metres away from the closest property.
Cross passage construction involves breaking into the side of the completed tunnel. This might generate some noise and vibration which may be heard/felt as groundborne noise in nearby buildings when transmitted through the ground to the surface.
Properties that may be affected are shown within the pink and blue lines on the map below. These lines represent the predicted noise levels in these areas.
