Marsh Lane is now closed to traffic (including pedestrians and cyclists) between Marsh level crossing and Stoke Mandeville School, because of the construction of the HS2 railway. It is unclear from road signs and web sites whether this closure will be permanent, even after work has been completed. Traffic between Stoke Mandeville and Marsh crossing is being diverted along A4010 Risborough Road and North Lee Lane.

Suggest no-entry signs at each end of the road, at the points described.
