The Chilterns Tunnel is a 15.8km bored tunnel. There will be four vent shafts and one intervention shaft located along the proposed line of route – Chalfont St Peter, Chalfont St Giles, Amersham, Little Missenden and Chesham Road. Its southern portal is located near Maple Cross. Its site will also house a compound during construction with all material from the bored tunnel coming here to be treated prior to being used elsewhere along the line of route. The northern portal is adjacent to South Heath.
