HS2 Chiltern Tunnel North Portal

Since the last visit a few days before christmas covering the north portal, a rather dark overcast day, it was a much better weather for the flight and I was therefore able to cover further ground. At the beginning of the video we see the pedestrian footpath overbridge foundations are complete. This particular bridge should afford views of trains entering and exiting the tunnel. They have completed the walls of the first porous portal and the and the formwork on the second portal has gathered pace, being the exiting tunnel the porous portal is shorter... i believe that the intervention shafts have released pressure.. Later in the footage we see an accommodation overbridge, the last AIUI before Leather Lane. At the end of the footage, the big gap in the treeline is where Leather lane overbridge will be…the plans of which are yet to be confirmed. Thanks for watching and supporting the channel. #hs2 #chilterns #civilengineering
