FROM HS2


Clarification on 2 sets of Roadworks that have been recently advertised by LBH Highways 
There have been lots of residents contacting LBH via email & social media about the 2 sets of works below that they would like to provide clarification on: 
HS2 Road Closure of Breakspear Road South conflicting with Cadent Gas Road Closure of Ickenham Road/Ruislip High Street Junction – Feb 2026 

  • HS2 Road Closure of Breakspear Road South goes ahead as planned from 14/02 at 7am until 18/02 at 7pm
  • Cadent Gas Road Closure of Ickenham Road/Ruislip High Street Junction that was due to start 14/02 will now commence 26/01 & finish 13/02
  • HS2 Diversion Route will remain as previously stated (including via Ickenham Road/Ruislip High Street Junction)
  • There was an error in communication between LBH Highways & Cadent Gas that has now been resolved over the requested dates

 
Road Closure of Breakspear Road South (Service Road) for Affinity Water Main Replacement – March to July 2026 

  • Notice issued by LBH Highways incorrectly stated Road Closure of Breakspear Road South main carriageway
  • Confirmation received from LBH Highways that only the Service Road will be closed (rather than main carriageway) in the following 2 Phases:
    • Phase 1 = 30/03/26 to 27/05/26 (8am to 5pm daily) – Breakspear Road South Service Road – House Number 64 to 114 Copthall Road West
    • (note – junction of Copthall Road West & Breakspear Road South is CLOSED during Phase 1 works)
    • Phase 2 = 16/06/26 to 24/07/26 (8am to 5pm daily) – Breakspear Road South Service Road – House Number 2 to 42
    • (note – junction of Greenacres Avenue & Breakspear Road South Service Road is CLOSED during Phase 2 works)

 
New Future Works Breakspear Road South – 24/7 Road Closure over 5 Days – Sat 14/02 at 7am until Wed 18/02 at 7pm
 
HS2/SCS have agreed a Road Closure of Breakspear Road South that will take place 24 Hours a Day over a 5 Day Period from Sat 14/02 at 7am until Wed 18/02 at 7pm. 
These works have been scheduled to take place during the Feb 2026 School Half-Term to cause as little disruption as possible but we are aware there is never a good time to close this road. 
Previously LBH had been informed by HS2 that all Road Closures on Breakspear Road South would be completed in 2025 but the following works are now required and unfortunately due to the methodology of the works they will require Full Road Closures to complete them: 

  • Rip-Rap Works – to install permanent paving and bollards to make safe the run-off area around a Drainage Swale
  • To carry out a Trial Hole across the whole carriageway for a Sewer Connection that was previously removed during HS2 Enabling Works (this is a new instruction from HS2 not previously known about by SCS or LBH) 

Please note – once the Trial Hole data is received, HS2/SCS will need to complete the Sewer Connection which will require a further Road Closure that they would look to request for the May School Half-Term or the School Summer Holidays. 

The Diversion Route is via Breakspear Road, Bury Street (A4180), Ickenham Road (B466), High Road, Swakeleys Road (B467). 
There will be no access via Breakspear Road South during the Road Closure for Emergency Service Vehicles.

1    SCS Noise Barrier Testing near Breakspear Road South – completion on Sun 11/01 – Postponed
The final Noise Barrier Test was due to be performed this Sun 11/01 within the HS2/SCS Site to the west of the entrance off Breakspear Road South. 

Update 09/01 – Please note that this has been postponed due to the weather forecasted for Sun 11/01 (Due to the sensitivity of the test it cannot be performed in less than favourable weather). I will update you once this final Test is rescheduled. 

The Acoustic Test will happen during the daytime (between 10am & 4pm) and will only last for a few minutes. It is unlikely to cause any noise disruption to residents

Breakspear Road South Road Closure for Conveyor Bridge Removal – Fri 28/11 at 8pm to Sun 30/11 at 8pm
 
HS2/SCS have agreed with LBH that Breakspear Road South will be Closed at the Chiltern Railway Bridge while the Conveyor Bridge that oversails the Highway is removed These works have been rescheduled to take place on the weekend of Fri 28/11 at 8pm to Sun 30/11 at 8pm.
 
The Conveyor Bridge carries the Conveyor system that was used to transport the TBM Spoil/Material over Breakspear Road South towards the Treatment Area at Harvil Road Gate 1. Now that both TBMs have completed their tunnelling between West Ruislip and Greenpark Way in LB Ealing the Conveyors are being removed and the Bridges that carry the Conveyor can also be removed.
 
These works will involve laying Matting on the road surface to protect it, then using a Crane to lower the Bridge to ground level before dismantling and removing it. The road would then be cleared with the Matting removed before reopening to the public.
 

  • There will be no Emergency Services Access during this Road Closure due to overhead lifting operations on the carriageway.
  • The Pedestrian Crossing which runs diagonally underneath the Chiltern Line Bridge will be closed for the duration of this Road Closure (also due to overhead lifting).
  • Notices & Signage will be installed in advance to advise walkers of the Pedestrian Crossing Closure.
  • The Diversion Route has now been confirmed with HS2/SCS and is the usual Diversion via Swakeleys Road, Ickenham High Road, Bury Street, Breakspear Road

HS2 hiccup – update

FROM HS2

We informed you last week that we were halting works across the London tunnels sections of the route following a serious near miss incident at our site at Green Park Way. We have now begun a safe restart across some of these worksites following a comprehensive review of safety procedures and leadership.

From Monday, 20 October, we will safely restart: Utilities work in South Hampstead area in Camden; The delivery of tunnel pre-cast concrete segments to the Willesden Euro Terminal in Ealing; and Earthworks in the West Ruislip area in Hillingdon. Additionally, a railway possession led by Network Rail will be carried out in the Old Oak Common area over the weekend to facilitate preparatory works.
Additional measures are being implemented by our contractor, Skanska Costain STRABAG joint venture, to ensure the safety of the workforce.

More sites will restart in due course as we continue to implement additional safety measures which are considered necessary following the review. We will not compromise on safety and sites will only restart once we are satisfied that all appropriate measures are in place to protect the workforce.

We will continue to keep you updated on further safe restarts in your area.

information update from HS2

Safety is our number one priority at Skanska Costain STRABAG joint venture (SCS) and across HS2. I’m writing to let you know that last week a serious incident occurred at our site at Green Park Way in Ealing. As a result, works are being safely halted across the London tunnels section of the route, including sites in Hillingdon. While no workers were physically harmed, SCS is undertaking a comprehensive review of safety procedures and leadership on their sites before a safe restart can take place.

Works will be brought to a safe stop and will remain on hold until we and HS2 are satisfied that all appropriate measures are in place to protect the workforce. We anticipate the review may take a number of weeks depending on the area and the type of work involved. We will continue to keep local communities updated
