BEAR Scotland continued to deliver significant investment in bridges and structures across the North West trunk road network during the quarter, helping to safeguard key transport links and improve the resilience of vital infrastructure.

Major refurbishment works were completed at two retaining walls alongside the A9 near Drumochter in July. The project involved carefully dismantling sections of deteriorating masonry facing, repairing the underlying reinforced concrete structure where required, and reconstructing the stonework to restore the walls’ appearance and structural integrity. The works have extended the service life of the structures while preserving their traditional masonry finish.

Significant progress was also made on the Tummel Wall Replacement project. The scheme involves constructing a new steel piled retaining wall designed to provide enhanced scour protection and resilience against future extreme weather events. By the end of September, 122 of the 140 main piles had been successfully installed. Once complete, the new structure will have a 120-year design life, helping to protect this key section of the A9 network for decades to come.

Summer also saw the start of works to replace the ageing Allt an Deabhtaich masonry structure with a modern soil-nailed retaining wall to provide improved long-term stability and resilience on the A85. Early works included site establishment, vegetation clearance, installation of protective slope netting and environmental measures to safeguard local bat populations. Throughout September, the project moved into the construction phase, with test anchors successfully installed and verified, drilling of the permanent anchors and preparatory works for the new sprayed concrete wall facing completed.

Work also continued throughout the quarter to restore the historic sluice gates at The Mound on the A9. As part of the project, old timber gates are being replaced and repairs are being carried out to the surrounding stonework. By the end of September, the first replacement gate had been installed, marking an important milestone in the refurbishment programme. The works will help preserve this landmark structure while improving water management and protecting the surrounding transport infrastructure.

A major milestone was also reached at Kessock Bridge with the successful completion of the tower modification project. The works have improved access for teams working within the bridge towers, making future inspection and maintenance activities safer, easier and more efficient. New wind monitoring equipment was also installed to provide more accurate information on wind conditions, helping to support bridge operations and traffic management. Alongside this, a new project got underway to repair and monitor the bridge’s tuned mass dampers, which help control movement during high winds. The scheme will support the long-term performance and resilience of this vital crossing.

Together, these projects represent a substantial investment in the resilience and longevity of the North West trunk road network. From strengthening retaining walls and protecting against the effects of extreme weather to preserving historic infrastructure and enhancing maintenance access, the works carried out during the quarter will help keep key routes safe, reliable and operational for years to come.
