Project Overview
Wills Bros are currently working with SSE Renewables to improve, modify and widen sections of approximately 4.6km of roadway on the A82 trunk road. The improvement of this forest track will facilitate construction of the Coire Glas Hydrodam; the first of its kind in over 40 years. The project also includes working in proximity to numerous holiday lodges as well as the construction of a new bridge over the Kilfinnan Burn.
Key Numbers
- Widening of a junction on the A82 to achieve the required width for hydro dam plant and equipment. The embankment immediately north of the junction will require some modification for this to be achieved and to ensure the adjacent residential properties are not affected by any abnormal load movements.
- Road upgrades including modifications to the horizontal and vertical alignment, installation of drainage and associated earthworks/engineering as required to construct the road.
- An offline temporary diversion road for use by residents and visitors to the area immediately south of Kilfinnan Road to avoid pinch points along the route and minimise congestion.
- Reinstatement of the road following Hydro Dam construction. The temporary road will also bypass Cruinneachaidh Bridge and Oighre Bridge due to space constraints and to maintain safe access for road users when replacing the existing structures.
- Offline construction of new sections of road where the existing road geometry and local physical constraints are unsuited to upgrade works.
- A new bridge across the Kilfinnan Burn. The existing bridge will be strengthened as part of the exploratory works to ensure its structural capacity is not adversely affected by traffic movements required for site enabling activities.
- Online verge widening and localised works along the road length, tying up with existing accesses.
