Carlbury Highway Embankment

Carlbury Highway Embankment

Following two landslips adjacent to the single carriageway A67 in Carlbury in County Durham, ByrneLooby carried out the design of the soil nailing works for remediation and stabilisation of the road embankment. The slope runs alongside a river valley and floodplain, extending approximately 400m in length and over 9m in height from the valley floor. The aim of the project was to increase the factor of safety of the slope to an acceptable level in the long-term, to strengthen the embankment slope and to prevent further landslips from occurring.

ByrneLooby was tasked by main contractor Graham Construction with producing the detailed design of the works to facilitate long-term stability of the roadway and supporting embankment. We were also required to design the ancillary works for this 0.5km scheme, which included the highway pavement reconstruction, design of road edge gabion retaining walls, drainage improvements, the Vehicle Restraint System (VRS) and habitat reinstatement works.
