Combe Down Tunnel is on the now-closed Somerset and Dorset Joint Railway main line, between Midford and Bath Green Park railway station, below high ground and the southern suburbs of Bath, England, emerging below the southern slopes of Combe Down village.
Opened in 1874, this 1,829-yard (1,672 m) long disused railway tunnel was once the UK's longest without intermediate ventilation.[2] The tunnel now forms part of the £1.8 million Two Tunnels Greenway walking and cycling path opened on 6 April 2013 and is the longest cycling tunnel in Britain.[3] Its custodian is Wessex Water.
