from HS2

The water treatment plant removal works are now ongoing until 28 February 2026. Works have been extended to accommodate access for other works.

These works will be 24/7 due to site constraints and the safety of the workforce. There will be lorry movements to remove the equipment during the day only. We will be emptying the treatment plant used to store water for our tunnel boring machines as it is no longer required. We will do this by using a hose connection into a silt buster system. Once emptied, we will disconnect and disassemble the plant and then remove from site during the day.

You may notice crane movements to lift the equipment for the water treatment plant and disassembly. Due to constraints on site some crane lifting may happen overnight. You may notice lights on site during nights, but we will position lights to avoid shining directly onto nearby properties. You may also hear white noise alarms during the day to ensure safety on site during the transportation of equipment. We will continue to monitor our working methods and noise levels to reduce disruption.

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.
