A63 Selby, North Yorkshire

Client: Highways Agency/ Skanska/ High Point Rendel
Completed: 2009

Selby Attenuation PondThe scheme has created a complete southern bypass of Selby Town, a distance of 9.7 miles, between the A63, to the west of Thorpe Willoughby, and the Ricall and Barlby Bypass. It also includes an opening (swing) bridge crossing of the River Ouse.

Moore Environment were the environmental co-ordinator and landscape architect for the project, responsible for briefing and managing a multi disciplinary team including ecologists and archaeologists, through the development of the detailed environmental design and the implementation of the environmental measures on site.

Key objectives for the scheme were met including:-

  • To integrate the road into its surroundings and contribute to the protection of the existing landscape quality. Priority was given to species that occur locally and there was also a reflection of species change along the route. Planting reflected the local forms such as hedgerows and tree belts.
  • To protect the existing landscape quality.Selby Cutting Through Sandstone Outcrop
  • To reduce the visual impact of the scheme and make the road and views pleasant for both the traveller and the local residents – leaving views of key features open for motorists and providing visual interest through species selection.
  • To protect existing wildlife and habitats and enhance biodiversity.
  • To minimise long term management.

Key environmental measures included:-

  • Translocation of selected species rich turfs from a Locally Important Nature Conservation Site (LINCS) which was partially lost.
  • Translocation of aquatic and emergent vegetation from a section of The Selby Canal for use in new waterbodies for the scheme.
  • Badger mitigation – when badger activity became evident during construction the road design was altered to accommodate 3 tunnels to mitigate potential impact on territories.
  • Grass verges designed as species rich grassland on low nutrient substrate.Selby Wetland Habitat
  • Reducing topsoil depths for areas of proposed open grassland to significantly reduce fertility, supress the establiishment of rank vegetation and reduce long term management.
  • Exposing rock at varying heights as a landmark feature where the scheme cut through wooded sandstone outcrop of Brayton Barff.
  • 18.3 hectares of native woodland planting, 11.5 km of mixed native species hedgerows and 1.8 hectares of species rich grassland. swales to balance and clean up road runoff before it reaches local watercourses.
