Cefn Viaduct

Cefn Viaduct is a railway bridge that spans the Dee river valley with 19 arches made of Cefn sandstone and faced with stone. The structure carries trains approximately 45 meters above the river level, supporting rail traffic between two important routes.

The viaduct was completed in 1848 under engineer Henry Robertson's direction and connected Chester to Shrewsbury. Its opening marked an important step in developing Britain's railway network during the mid-1800s.

The structure shows the craftsmanship of Victorian builders and remains part of Welsh industrial heritage. You can admire the arches from below in the park, watching how they cross the valley.

You can best view the viaduct from the nearby Ty Mawr Country Park, where walking paths and viewpoints are available. The park offers good spots to photograph and examine the structure from different angles.

When it opened in 1848, it held the title of Britain's longest viaduct, making it a remarkable achievement of Victorian railway engineering. The span demonstrated the technical ambitions of the era.
