News on HS2 in Hillingdon

We are working closely with our construction partners to review the works on all our construction sites in line with Government and Public Health England (PHE) advice on dealing with Covid-19. The Government’s current Covid-19 strategy makes clear that construction activity can continue as long as it complies with this guidance, which you can see by clicking here.

The below works are going ahead as our contractors are confident that they can operate in line with PHE and industry guidance, protecting our staff and the communities in which they are working.

We previously let you know about our works around the Colne Valley including Moorhall road and the A412. We have an update on these works with more detail on lane and road closures. For more information on the below works, including maps, please see the Works Update by clicking here .

We previously notified the community about our work around Moorhall Road, from 27 July there will be a lane closure with traffic flow in both directions controlled by temporary traffic lights until October 2020. There will also be overnight full road closures of Moorhall Road in late August / early September. For more information, including maps, please see the Works Update by clicking here .

As we prepare for the main construction works to start, we will be undertaking a range of work sat our sites across the Colne Valley.

A lane closure on the A412, near the Denham Water ski club entrance, will be in place to allow us to work on both sides of the highway, initially to undertake vegetation works alongside the A412 North Orbital followed by the construction of a new construction access road crossing of the A412. The lane closure will be managed by two way traffic lights. This will be required for up to four months and will operate 24 hours per day and seven days a week.

We will also be putting in place full A412 road closures at night during some weekends. This work is being undertaken during at night and weekends to reduce disruption and for the safety of the public. The weekend closures on the A412 are anticipated to be required during the period 29 August to 6 September and will be in place from 9pm to 5am.
