This is a railway viaduct made of rock-faced grey limestone, constructed with large squared blocks. It features seven broad arches supported by short square piers, each with a raised band at the point where the arches begin. There is an additional raised band of rock-faced stone located beneath the parapets, which are topped with rock-faced stone copings.
