Update: cross passage construction near Rockware Avenue, Greenford

What we are doing

We planned to building cross passage 16 near Rockware Avenue, Greenford from 18 June to 14 July 2025, please follow the link to previous notification. The dates has now changed.

We’re building cross passages between the railway tunnels to allow HS2 passengers to get to a place of safety in an emergency. They are about every 500 metres on the tunnels route.

To build the cross passage, we will break into the side of the completed tunnel. This might cause some noise and vibration, which may be heard or felt as ground borne noise in nearby buildings. We’ll work 24 hours, seven days a week. To avoid overnight disturbance, we’ll limit noisy activities to between 7am to 10pm Monday to Sunday and carry out quieter works at night.

Cross passage 16 is about 29 metres below ground and lies within a thick layer of London clay, which will reduce noise and vibration during these works.
