HS2 Works Notification: Temporary traffic lights on Pheasant Hill, Chalfont St Giles

We’re writing to let you know about some  planned works that we will be carrying out in your area.


The tunnel boring machines (TBMs) which are tunnelling through the Chilterns for the next three years will be moving through Chalfont St Giles early next year and we need to monitor ground movement before, during and after they pass through.


What will we be doing?

We are installing equipment, to monitor the ground during the progress of the TBMs as they move through the area early next year. We will be placing monitoring equipment on Pheasant Hill between 9.30am and 3.30pm on Friday 22 October. To allow this to be done safely we will be operating temporary three-way traffic lights.

We’re committed to keeping you informed about the planning and delivery of the railway in your area with regular updates on progress.
