Gloucestershire County Council has released timelapse footage of the remedial work carried out after a 2013 landslip.
The B4058 at Horsley Hill in South Gloucestershire has been fully reopened after a £0.55M scheme to rebuild the road using a “pinned retaining structure” after part of it slipped down a steep sided wooded valley.
After the 2013 slope failure, the carriageway was partially open to one-way traffic until last summer when the major works on the scheme began and the road was fully closed.
Consultant Amey and contractor Graham Construction planed off the highyway surface and excavated 2m before 94 pre-cast concrete ‘L’ sections were anchored to the underlying rock.
The reinstatement of the slip area below the highway included the installation of soil stabilisation matting, together with imported topsoil on the slope, with an erosion control blanket covering the slip area.
The road fully reopened last month.
