HS2 Colne Valley eastern area to Northolt West tunnel portal

Nearly 3 months since i last visited and progress has been made on embankments between the overbridges.
At the southern end of the Colne Valley Viaduct will be a short embankment between Copthall Green tunnel and the London tunnels (West Ruislip) in north west London.
The 2 completed bridges adjacent to Chiltern mainline are over Breakspear Road South and the river Pinn.
The nearby chiltern line so close but no planned connection…
