What we are doing

The Colne Valley Viaduct crossed Moorhall Road in August this year. We now need to install some safety railing on either side of the viaduct. To ensure this work is done safely we will need to close Moorhall Road at the location of the viaduct, between the River Garden Public House and the junction with Link Way and Savay Lane. Access will be maintained for residents. The public footpath will remain open with some minor diversions.

The closure is early in the morning of Wednesday 3 January 2024 between 1am and 5am.

Ickenham Rd (West Ruislip Tube Station) – Emergency Affinity Water works

LBH were informed on Thur 23/11 that Affinity Water believe there is a water leak under Ickenham Rd near to the Tube Station that requires Emergency works to repair the leak. Overnight from Thur 23/11 (10pm) into Fri 24/11 (6am) Affinity Water closed off the Westbound Lane on Ickenham Rd and put temporary 4-Way Traffic Lights in place so they could excavate into the carriageway on the Tube Station side of the road to try and trace the leak.

The temporary Traffic Lights were removed by 6am on Fri 24/11 and traffic is flowing as normal but Affinity Water plan to return on Fri night 24/11 (from 10pm) and reinstate the carriageway overnight into Sat 25/11 using the same temporary 4-Way Traffic Lights. They hope to have completed the works by 6am on Sat 25/11 and then traffic flow should return to normal.

The leak now appears to have been traced to be on the Eastbound carriageway so Affinity Water will have to approach LBH to agree how they tackle the repair while causing as little disruption as possible. If the location of the leak is near to the Footway then a Narrow Lane Traffic Management setup may be utilised to maintain the flow of traffic but if the location is further into the carriageway then further temporary Traffic Lights might be required (with the works being carried out at night).

As always LBH Officers will try to mitigate the effects on the Road Network as best as possible to keep any impacts on traffic to a minimum.
Breakspear Rd South Night Time Lane Closure – Mon 27/11 from 10pm until 5am on Tue 28/11

LBH have provided consent for HS2/SCS to carry out some surveying of a Thames Water Foul Sewer Manhole which will require a Lane Closure of Breakspear Rd South at Night on Mon 27/11 from 10pm until 5am on Tue 28/11.

Details of works:

Night Time Lane Closure on Breakspear Rd South – Mon 27/11 from 10pm until 5am on Tue 28/11:

• The Lane Closure will be on the Southbound carriageway and there will be Traffic Lights in place to control the traffic flow
• 3-Way Traffic Lights with Heads on Northbound, Southbound and at HS2 Haul Rd Crossing
• Haul Rd Crossing Lights on demand – as outside of Core Working Hours very little HS2 traffic crossing Haul Rd expected

Reason for Works:

• Internal survey of Thames Water Foul sewer manhole involving confined space man entry

Following receipt of funding from the HS2 Road Safety Fund and following requests from residents, a Vehicle-Activated Sign (VAS) has now been installed on Breakspear Rd South near to the junction with Swakeleys Rd. If a vehicle approaches the Sign at a speed more than the 30mph Speed Limit on this road, the VAS Sign will illuminate and encourage the driver of the vehicle to ‘SLOW DOWN’.

This is in addition to a number of other VAS Signs that were installed in 2022 on roads in the north of Hillingdon to reinforce the reduction in Speed Limits on several roads in the area (a scheme also paid for from the HS2 Road Safety Fund).
