New drone footage showcases National Highways restoration of iconic Riddings Viaduct

Newly released drone footage reveals the scale of restoration work carried out on the historic Riddings Viaduct.

National Highways’ has completed a major programme of repairs to secure the long‑term future of one of the most distinctive structures spanning the England–Scotland border.

The Grade II* listed viaduct, which sits on the former Langholm branch railway line, has undergone extensive conservation work to preserve its life and character.

National Highways  has completed a major programme of repairs to secure the long-term future of the structure, which was built in 1864 and has stood unused since the railway line it carried was closed in 1967.

Work included repairing and filling gaps in the stonework, fixing damaged sections and restoring the railings along the bridge's edges. All repairs were carried out using materials that closely match the original, to preserve the viaduct's historic appearance.

National Highways engineer Colin McNicol, said:“Working on a structure that spans two countries brings unique challenges. We’ve worked closely with partners in both England and Scotland to meet the distinct heritage and ecological requirements on each side of the border.

“Our work will preserve this iconic viaduct, allowing people in both countries to enjoy its beauty for many years to come."

Today, Riddings Viaduct is protected as a historically important structure on both sides of the border, and the new footage gives the public a rare chance to see inside it, as the bridge itself is closed to visitors.

The viaduct has a rich economic and historic legacy and once carried trains between Riddings Junction near Carlisle and Langholm in Dumfries and Galloway, connecting previously isolated border communities and supporting local industry.

Its unusual route crossed the England–Scotland border three times in under 20 miles, including over the viaduct itself.
