Kier built the £1.5m bridge to access the most recent extension to the site, known as Braehead Farm. Only accessible by crossing the River Nith, the area contains 1.5 million tonnes of coal.
Built to withstand the weight and size of large 300-tonne excavators, it is expected that the bridge will remain in place once mining activities are completed and will be adopted by the local authority for public use. Designed to minimise the impact to the river bed and banks, the concrete Bebo Arch System comprises a series of interlinking concrete arches that span the River Nith. Compacted backfill is placed behind the arches and wing walls complete the bridge to road level.
Kier Mining director Mark Harrington said: “This is an exciting time for Greenburn; we have recently reached the incredible landmark of having produced and dispatched five million tonnes of coal. This new bridge will enable us to access an additional 1.5 million tonnes, protecting the jobs of our people here and making an important contribution to the local and wider Scottish economy.”
