Harvil Road night-time closures

HS2/SCS will be carrying out 2 Night Time Road Closures on Harvil Road (at the new Bridge over the Chiltern Line) over the late May Bank Holiday Weekend to allow for a crane to come in and lift the scaffolding materials down to track side so they can be erected under Railway Possessions to carry out surveys & testing to the Bridge at track level.  

The 2 Night Time Road Closures would be:  
Sat 23/05 at 10pm to Sun 24/05 at 5am
Sun 24/05 at 10pm to Mon 25/05 at 5am  

It was agreed to use the Bank Holiday Weekend so if there is any reason for an overrun, there would not be the usual Monday morning traffic.
Additionally, these dates come just before the HS2/Align works on Harvil Road / Dews Lane that are due to go out under 3-Way Traffic Lights (9.30am to 3.30pm) from 03/06 to 23/06.  
The Traffic Management Plan below shows the extents of the Road Closure in Blue.
