Please see the updates below regarding HS2 in Hillingdon over the next week and beyond. Please note the upcoming Road Closures of Harvil Road from the 30/01 and Newyears Green Lane from 31/01, but that the scheduled Night Closures on Breakspear Road South this weekend have now been postponed.

Breakspear Road South – Night Time Road Closures – CANCELLED THIS WEEKEND

The scheduled Night Time Closures of Breakspear Road South this weekend (Friday 27/01/23, Saturday 28/01/23 & Sunday 29/01/23) have been postponed.

LBH Officers have raised concerns at the amount of activities that would have been carried out under these closures this weekend and further discussion and planning will now happen between LBH & HS2/SCS to ascertain the full programme of works required at this location, and when best these works can be coordinated so that they cause as little disruption as is possible. I will keep you updated on progress in future updates.

Harvil Road Realignment Works Programme – ROAD CLOSURE IN PLACE FROM MONDAY 30/01

Background – HS2/SCS have presented details of their programme of works for the Realignment of Harvil Road due for completion by October 2023. There are a lot of works that will involve Traffic Management on the current Harvil Road in 2 areas where the new road will ‘tie-in’ with the existing road, around the Skip Lane junction (which is being rebuilt and will be incorporated into the new Realigned Harvil Road which will run over the Chiltern Railway Line on a new Bridge) and near the Dogs Trust (where HS2 Gate 2 is being relocated, and various other Utilities works are being done).

The works change over from the current phase of 4-Way Traffic Lights to a FULL ROAD CLOSURE between Shorthill Cottage and Certas Oil Depot from Monday 30/01/23 at approximately 6am. The road will then be closed for 3 weeks until the 19/02/23.

Skip Lane Phase 4

3 weeks – FULL ROAD CLOSURE – 30/01/23 to 19/02/23

Newyears Green Lane – ROAD CLOSURE IN PLACE FROM MONDAY 31/01

There are planned works by SSE scheduled from 31/01/23 to 06/02/23 that will close Newyears Green Lane, with the area of the closure between the LBH Civic Amenity Site and the HS2 Site (as shown on the Map below).

At the same time Harvil Road has a full road closure in place by Skip Lane junction (between 30/01 and 19/02) so this closure of Newyears Green Lane should not be as impactful as it would be if Harvil Road was fully open from the south.

Upcoming works on A40 Western Avenue

TfL have scheduled works on the A40 Western Avenue from mid-February until the end of April between Denham Roundabout and East Acton that will close parts of the road at night. There will also be some lane closures to contend with during the day (see details below):

Tunnel Boring Machines Launched from West Ruislip
HS2/SCS launched the 2nd Tunnel Boring Machine (TBM) named Caroline at the West Ruislip Portal Site at the end of October 2022 (following the launch of the 1st TBM called Sushila in early October 2022). The 2 TBMs will operate 24 hours a day 7 days a week and will tunnel from West Ruislip towards Green Park Way in the London Borough of Ealing and it is expected that tunnelling works will take until June 2024 to complete.

Rail Siding Test and Segment Delivery to West Ruislip

With the TBMs now fully operational, HS2/SCS need to increase the deliveries of Tunnel Segments (the concrete ‘rings’ required by the TBMs to construct the tunnel lining as they progress) to the West Ruislip Portal Site.

There is a new Railway Siding that has now been constructed that will provide direct access from the Chiltern Line into the Segment Yard at West Ruislip so that Tunnel Segments can be directly delivered into Site by Rail rather than by road/lorry. HS2 are now ready to test the Rail Siding and plan to carry out the first tests over the next couple of weeks. If these tests are successful HS2 plan to run the train five nights each week although there may be periods when this extends to seven nights per week.

The plan will be for one train to arrive at West Ruislip each night delivering 20 rings, each comprising of 7 segments. There will be a slight overlap and HS2 will continue with lorry deliveries in the short term until they have built up a stockpile of Segments. The volume of rail traffic on the Chiltern Line through West Ruislip means that the train can only deliver Segments at night so the train will arrive at West Ruislip around 11pm. The locomotive will then divide the train into two parts and shunt them into the Siding. The locomotive will then shut down while the gantry crane unloads the Segments, and the locomotive will restart at around 6am and shunt the train back into one piece prior to departure at around 7am.

Utilities Updates:

HS2 (through its contractors SCS) is undertaking a series of essential Utilities works in advance of the Tunnel Boring Machine (TBM) travelling from near West Ruislip Tube Station under the ground towards Old Oak Common in Acton. Any present Utilities along the route (such as gas, electricity, water and sewerage pipes) have to either be diverted or be renewed or reinforced so that the vibration from the movement of the TBM travelling underneath them will not cause breakages and damage to the existing pipework.
