News on HS2 in Hillingdon

HS2 contractors Align JV will be carrying out temporary survey works on the M25 on both the clockwise and anticlockwise carriageways between Junction 16 (Denham Interchange) and Junction 17 (Maple Cross Interchange).

The survey work, which will be carried out in phases during the daytime and overnight, will last for about three weeks. Works will start on Monday 12 April and are planned until Monday 3 May 2021 . Details of the phasing, dates and carriageways affected are listed in the table overleaf. There will be lane closures in place on both carriageways from 9:30am to 4pm each day and overnight from 10pm to 5am whilst the surveys take place.

Advance warning signage will be put in place prior to the works taking place. Whilst disruption will be kept to a minimum, we would remind road users to plan their journeys and to be aware of the temporary closures of the hard shoulders and some of the lanes to allow the works to be carried out safely.
