At a recent HS2 Community Forum in Balsall Common three potential tunnel options were revealed to community representatives. HS2 officials confirmed all the options were technically possible to construct but the final decision on implementation rests with the Secretary of State, meaning any or even none of the options could be selected.
The three options displayed on plans were:
OPTION 1: a 2.5km tunnel linking the planned deep cutting and cut and cover tunnel at Burton Green, passing underneath the West Coast Main Line (WCML) and emerging close to Marlowes wood in Berkswell. Cost £98m
OPTION 2: a 4.8km tunnel replacing the planned cut and cover tunnel beneath Burton Green and starting a little further south of Burton Green, passing underneath the WCML, emerging close to Marlowes wood in Berkswell. Cost £177m
OPTION 3: a 6.5km tunnel from the approach to Burton Green, passing underneath the WCML, and emerging closer to the gravel pits in Berkswell. This would allow some straightening of the line underground to “cut the corner” and therefore move the line further away from Hampton in Arden. Cost £286m
Meeting attendees were prevented by HS2 from making copies of the plans.
