Network Rail, in collaboration with principal contractor AmcoGiffen, evaluated the viaduct’s condition. Located in the Scottish Highlands and renowned globally due to its appearance in the Harry Potter films, the viaduct has undergone extensive maintenance to ensure its longevity for future generations. A plaque celebrating the centenary of the viaduct was unveiled on the 12th July 1997 by Sir William McAlpine, now head of the family construction firm founded by his great-grandfather. During World War II, the viaduct was regularly ‘blown up’ in exercises by Special Operations Executive agents, who trained in acts of sabotage in this area before being sent into occupied Europe. A spectacular engineering construction which curves across Glen Finnan 13 miles (21 km) west northwest of Fort William, the Glenfinnan Viaduct carries the West Highland Railway over the River Finnan on its way north to Mallaig. Our highly skilled team faced numerous challenges, from preserving the viaduct’s original integrity to implementing modern engineering solutions.
- Meanwhile, rope access technicians descended from the viaduct, reaching and restoring areas that would otherwise be inaccessible.

- The viaduct is 380m (1248 feet) in length, reaches 30.5m (100 feet) in height, curves on a 201m (660 feet) radius and cost of £18,904.
- “Over a century after it was first built, Glenfinnan Viaduct still stands strong today, in no small part due to Network Rail’s excellent care.”
- Ballast is the stone material under the track that maintains stability, drainage and prevents damage to the underlying structure.
- Historic Environment Scotland have designated the structure as Category A, the highest level, meaning it’s of significant architectural and historical interest.
- A two-year pilot project enhanced the natural habitat by planting trees across approximately 200 hectares to protect, restore and expand rainforest and peatland habitats.

As part of its preservation, Network Rail refrains from cleaning off efflorescence marks from the rain as it drains through, ensuring the character of the structure remains. Our highly skilled team faced numerous challenges, from preserving the viaduct’s original integrity to implementing modern engineering solutions. Meanwhile, specially trained rope access technicians descended from the viaduct, reaching and restoring areas that would otherwise be inaccessible. The structure in the Scottish Highlands, made famous worldwide by the Harry Potter films, has undergone an extensive maintenance programme to safeguard its future for generations to come.
Historic Environment Scotland has classified the viaduct as a Category A structure, indicating its significant architectural and historical value. The structure comprises twenty-one semi-circular arches and was the first viaduct in the world to be fabricated solely from concrete, an unusual material for the time. Historic Environment Scotland have designated the structure as Category A, the highest level, meaning it’s of significant architectural and historical interest.
Thus, the viaduct is sometimes referred to as “The Harry Potter Bridge”. The 2007 series of notes issued by the Bank of Scotland depicts different bridges in Scotland as examples of Scottish engineering, and the £10 note features the Glenfinnan Viaduct. It is a popular tourist event in the area, and the viaduct is one of the major attractions of the line. Located at the top of Loch Shiel in the West Scottish Highlands, the viaduct overlooks the Glenfinnan Monument and the waters of Loch Shiel. Additionally, deer fencing has been installed at Ardmolich to safeguard the newly planted native woodlands from overgrazing. A two-year, industry-leading pilot project enhanced the natural habitat by planting trees across approximately 200 hectares to protect, restore and expand rainforest and peatland habitats.
The project also included the installation of new safety handrails for staff working at height and the renewal of ballast retention systems at the structure’s ends. Engineers conducted detailed assessments of the viaduct’s condition and carried out sympathetic concrete repairs to maintain its original aesthetic. This project aims to replace outdated boundary fencing, ensuring the track remains safely separated from public areas. “Over a century after it was first built, Glenfinnan Viaduct still stands strong today, in no small part due to Network Rail’s excellent care.”

Originally built at a cost of £18,904, this amount is equivalent to approximately £2 million today. Meanwhile, specially trained rope access technicians descended from the viaduct to reach and restore otherwise inaccessible areas. Engineers also worked within the River Finnan to shield the piers from erosion caused by the swift river currents. Ballast, the stone material beneath the track, ensures stability, drainage, and protects the underlying structure. Additionally, new safety handrails were installed for staff working at height, and ballast retention systems at the structure’s ends were renewed.
This includes a two-year pilot project focused on enhancing natural habitats through tree planting across approximately 200 hectares and the installation of deer fencing at Ardmolich. The restoration of the Glenfinnan Viaduct forms part of a wider programme of environmental and infrastructure improvements in the area. Crucially, work was undertaken in the River Finnan to protect the viaduct’s piers from harrycasino erosion caused by the river’s flow.

- Every step of the process required meticulous attention to detail and a deep respect for its heritage.
£3.4m Restoration For Historic Glenfinnan Viaduct
Ballast is the stone material under the track that maintains stability, drainage and prevents damage to the underlying structure. A two-year pilot project enhanced the natural habitat by planting trees across approximately 200 hectares to protect, restore and expand rainforest and peatland habitats. The viaduct is an icon of Scottish tourism, drawing thousands of visitors each year.
Concrete repairs were carried out across the structure sympathetically, taking care to replicate its heritage appearance. The viaduct is a major draw for tourists, with many travelling on ScotRail services and the Jacobite steam train, known as the ‘Hogwarts Express’ in the Harry Potter films, operated by West Coast Railways. Its significant architectural and historical importance is recognised with a Category A listing by Historic Environment Scotland. Network Rail, in collaboration with principal contractor AmcoGiffen, completed the year-long programme to ensure the long-term preservation of the viaduct.
Engineers complete £3.4m Glenfinnan Viaduct restoration
It is built from mass concrete and has 21 semicircular spans of 15 metres. It is the longest concrete railway bridge in Scotland at 416 yards (380 m), and crosses the River Finnan at a height of 100 feet (30 m). The recent restoration work has further highlighted its importance, not only as a vital piece of railway heritage, but also as a beloved film star in Harry Potter, for which we proudly provided The Hogwarts Express.” These bridges were mostly designed with an exposed concrete finish, rather than being faced in stone, and are the earliest railway bridges of this style in Scotland. Historic Environment Scotland has designated the structure as Category A, the highest level, meaning it’s of significant architectural and historical interest. Additionally, Network Rail is investing £500,000 to renew over five kilometres of lineside fencing near the viaduct to improve safety.
