HS2 has chewed up part of the Hertfordshire Border Walk between West Hyde and Chorleywood. I walked it to see how it can be done. I took a pre-HS2 map (Explorer 172 – Chiltern Hills East) as a guide to where the paths ought to go.
HS2 have said that they will restore the footpaths when the works are completed, and there are signs of the blocked paths’ being preserved, but it could be several years yet before they are opened, and we cannot tell what alignments will be left. The county border is unmoved and immemorial, even if the paths which once defined it move.
From the A412 Uxbridge Road, the mouth of the footpath on the county border has been obliterated by the HS2 work site. However there is a way round, and HS2 have posted a diversion map on a tree. I walked south along the road into Buckinghamshire, under and then alongside the massive new viaduct. By a layby is a small path up through the woods, to a lane (Tilehouse Lane) where I turned north again. The lane used to run through, but is now cut off by the construction site: it ends where the border path resumes.
I followed the path eastwards therefore, along the edge of the wood, with the vast site to my right, along the county border, down across a new works access road, and then it is closed again, with a diversion.
This diversion is the same as the one I did some years ago – then I think I had to work it out on my own, and took a wrong turn somewhere that led me into difficulty, but this time the diversion is shown on maps attached to signposts. It took me south and round and under the M25 in a foot tunnel, and to a road at the edge of Chalfont St Peter. Walking north along the road to start of the village, there is path back eastwards, tree-lined and then out into a broad field. It is well defined now, skirting the side of a mobile home park to the left, and to an access road close by the M25. A new local road has been built since the map was printed, but this is the end of the diversions. They added perhaps two miles to the route.
I headed down Shire Lane, which runs along the county border. Very soon the road swings left, but Shire Lane, the old road, is straight on, a tree-lined path, emerging at a corner and resuming being a road, past the Dumb Bell Inn and on northwards. When the road hits a T-junction, it is stil straight ahead: Shire Lane has become a woodland footpath (with Newlands Park to the left: the Chiltern Open Air Museum is in the Newlands Park Estate).
After a dog-leg, the path heads north again through woods a house comes into view and the path becomes a road, and leads down into Chorleywood.
It is a lovely stretch of walk, that took just a few hours. It will be better when the convulsing works are finished and the paths are put back, but I will take it as it is for now.

Maps
The route spreads over a wide are and a series of maps is needed to complete it. It might be done with standard Landranger maps, though the additional detail of an Explorer map can be very helpful.
