Cross passage construction near Eastcote Lane, Northolt

What we are doing

From 6 to 31 January 2025, we will be constructing cross passage 23 near Eastcote Lane, Northolt. There will be periods of noisy work. To avoid overnight disturbance, we have agreed with the local authority to limit noisy activities to between 7am and 10pm Monday to Friday, 7am to 6pm on Saturday and 10 am to 3pm on Sunday.

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/felt as ground borne noise in nearby buildings when transmitted through the ground to the surface.

This cross passage is 23 metres deep and about 45 metres away from the closest property.
