The 26-foot (8-metre) long replica, constructed using approximately 100,000 Lego bricks, boasts two functional train tracks and was created by four members of the Lego UK Railways (LUKR) group.

This appearance marks the model’s first visit to Scotland. According to the LUKR website, the intricate build was spearheaded by core members Joe, Levi, Shane, and Richard, with additional creative elements, like boats and houses beneath the bridge, designed by contributor Lewis. The scenic landscaping for the display was completed with help from Joey, Andrew, Sammy, and William.

The model first premiered at Bricktastic 2025 in Manchester and features remarkable engineering details, including around 5,000 LEGO Technic pins and approximately 600 1×16 red Technic bricks per cantilever arm.

To accurately capture the dramatic proportions of the original structure, the builders used selective compression, crafting the model at various scales: 1:308 for overall length, 1:275 for height, 1:46 for the tallest components, and roughly 1:100 for width.

Lego fans will have the chance to see the model in person at the Edinbrick charity Lego show on May 10 and 11, where it will be a key attraction of this year’s event.

Doug Adamson, lead organiser of Edinbrick, shared his excitement: “We were thrilled when LUKR wanted to return this year. Once we heard about the Forth Bridge model, we knew we’d need more space. What could be more fitting than showcasing the largest Lego Forth Bridge ever built in the very city that overlooks the real one?”

The original Forth Bridge, a masterpiece of 19th-century engineering, was completed in the 1880s and officially opened in 1890. Stretching across the Firth of Forth, it connects Edinburgh with Aberdeen and was crucial in establishing a continuous East Coast rail line from London to northern Scotland.

Famed for its cantilever design, the Forth Bridge was the first major steel structure in the world and held the record for the longest single-span bridge for 28 years. Its total length is 2,467 metres, with the main span measuring 1,630 metres. The bridge soars 110 metres above the water and rises 137 metres from its foundations.

After undergoing a full restoration completed in 2012, the bridge was designated a UNESCO World Heritage Site in 2015—Scotland’s sixth. The nation added a seventh in 2024, with the Flow Country gaining global recognition for its environmental and cultural significance.
