The Roundhill Tunnel are a pair of bored tunnels in Folkestone in Kent. They were built as part of the general works for the Channel Tunnel. The tunnels themselves are a D2 arrair and are bored into a chalk hill. The building works took three years to do. The western portals are on a pair of viaducts that take you to the Castle Hill Interchange.
