“Essential” slope stability work on the northern side of Ironbridge Gorge has started today, according to Telford and Wrekin Council.
The piling work is planned to halt ground movement affecting Lloyds Road and will use a similar approach to the work currently being undertaken at Jackfield on the other side of the River Severn by Keller.
“The land has been slipping for years and we are now at a stage where we can’t allow it to slide any further because the road will start to be affected,” said Telford and Wrekin Council councillor Richard Overton.
The work is expected to take six weeks to complete.
According to the British Geological Society, the Lloyds copse landslide is actively moving as a series of rotational and translational slides. “Crags of sandstone have moved down from their outcrop near the top of the hill, bringing with them the overlying thick till,” according to a BGS report. “Geological faults, ground water, surface water, the nature of the geology, construction and mining are all associated with the instability of this slope.
“This landslide is within the Halesowen Formation which is particularly susceptible to movement in this area as it includes more silty strata and less sandstone than elsewhere. Buildings and roads have been affected by the landslide.
“Considerable investigative work has recently been undertaken by Telford and Wrekin Council on this landslide to develop appropriate management plans to anticipate and mitigate the effect on the land usage.”
