Concerns have been expressed about the temporary alterations to the Kenilworth Greenway due to HS2. See this facebook post and also this one.
The temporary paths will probably be in place until HS2 is in operation, perhaps 2030 or later. Once HS2 is in operation, a permanent replacement will be opened parallel to HS2, on its south side between Burton Green and Berkswell station.
