The Cober Valley Viaduct is a Victorian Viaduct which was built in the 1880's just outside the hamlet of Lowertown, near the town of Helston in Cornwall, UK.
The viaduct was part of the Helston Railway and was used from 1887 to 1964. The viaduct has been abandoned since the Helston Railway closed.
The viaduct is also known as 'Lowertown Viaduct'.
