A fascinating video report by Forgotten Relics about the fabulous Tidenham Tunnel, constructed in the 1870s as part of a railway connecting Chepstow and Monmouth, but destined to become the second longest tunnel on the country’s cycle network when it reopens as part of the Wye Valley Greenway.

Work to reopen the 1,188-yard long Tidenham Tunnel has made considerable progress in 2020, with tarmac laid by a contractor at the start of September followed by a subsequent volunteer workcamp which saw lighting installed and recesses bricked-up to encourage bat use.

Dating from 1876, the structure is unusual in that it started out as two tunnels; the small, intervening gap was later arched over and backfilled.

It’s hoped to open the greenway – which will connect Chepstow to Tintern – in the spring of 2021.
