HS2 November 2017 Update

23rd November 2017

The closure of Chalfont Lane, Maple Cross by HS2 Ltd for approximately 8 years as part of works to build the railway, has been put back from the original date of the 8 November 2017 to Monday 27 November 2017. For further details on the closure please refer to the October update.

Looking ahead there will be archaeology trial trenching south of Chalfont Lane and west of the A412 from late December / early January.  There will also be survey works in various locations from mid January.  Also from January, just over the border in Buckinghamshire, there will be ‘ecological mitigation’ works (tree planting).

The Additional Mitigation Plan of the Colne Valley Regional Park Panel has now been published. The mitigation plan identifies additional mitigation and enhancements in furtherance and beyond the mitigation proposed within the High Speed Two (HS2) proposed scheme. HS2 Ltd has made an assurance to work with the Colne Valley Regional Park Panel to deliver the key proposals in the additional mitigation plan, which will include making £3 million available to support its delivery. 

A HS2 Independent Construction Commissioner has been appointed to mediate unresolved disputes.  If you have an enquiry or want to make a complaint, a Freephone Helpline is provided by HS2 (see details below).  If a response to a complaint about Phase One construction is unsatisfactory, or remains outstanding contact the commissioner on 0300 123 5365 or to look into the case.
