The works which are being undertaken by Network Rail on behalf of Transport Scotland involve the construction of the new pond and associated landscaping works, including wetland planting, to benefit the wider ecology in the area.
Over the next eight weeks, the area will be cleared and lined before the surrounding area is landscaped to create the 60 by 20 metre pond which will be left to mature for a year before the contents of an existing pond are relocated.
The above follows earlier works undertaken in autumn 2021, during which a Tunnel Boring Machine (Mole) tunnelled under the railway for approximately 33 meters through a mixture of sand, gravel and rock over a period of four days, to create an overflow outfall for the new pond.

Ecology assessment undertaken during the development of the project has highlighted the existence of a rare sub-species of the caddisfly. The new pond and landscaping will help protect the habitat that supports this rare species and enable its future translocation to this location.
Malcolm Mcgowan, Network Rail Project Manager for the work at Lynebeg said: "The construction of this pond will recreate the existing caddisfly habitat and, following a period of establishment, will support the relocation of the existing caddisfly to the new pond, which is considered to bring significant environmental benefits to the A9 project.’’
"Promoting positive environmental impacts and supporting biodiversity is an important element of the overall A9 Dualling project and the work we will do in the coming weeks will continue to benefit the local ecology for generations to come.
"There will be a range of construction plant involved in the creation of the pond and though the location is relatively rural, we are advising local people to be aware of the additional activity and vehicle movements during this important work."
Work is scheduled to last approximately 8 weeks.
