THE AUCHENKILNS JUNCTION, CUMBERNAULD WAS ONE OF THE BUSIEST ROUNDABOUTS IN SCOTLAND. THIS £22M DESIGN AND BUILD CONTRACT BY MORRISONS FOR TRANSPORT SCOTLAND CREATED A GRADE-SEPARATED JUNCTION ENTAILING REPLACEMENT OF THE EXISTING ROUNDABOUT WITH FOUR SLIP ROADS, AN OVER BRIDGE AND TWO NEW ROUNDABOUTS.
The local authority viewed the scheme as an opportunity to create a new local identity and the two roundabouts and bridge abutments received more formal design solutions.
AHR was engaged as Landscape Designers and Environmental Consultants to design feature landscapes, noise barriers, planting solutions and new habitat creation in the form of a native species woodlands, biodiverse grasslands and a SUDS detention pond. Extensive depths of peat made for a technically difficult project in terms of design solutions and working conditions. The sustainable solution reused all peat material on site. Extensive consultation has involved Scottish Natural Heritage in order to enhance the affected Ravenswood Marsh Wildlife Site with Marsh Violet seed collection to recreate suitable small-bordered fritillary butterfly habitat. The work also preserved an archaeological site and involved Historic Scotland.
