Highways England has said that a lane closure on the M11 near Girton has been lifted following completion of repairs to a series of unexpected voids beneath the motorway.
Highways England found the voids, which were up to 3m deep in place, in September and worked with Interserve and WSP to fast track the repairs.
“Safety is at the heart of everything we do at Highways England, and once we realised the extent of these voids underneath the M11 we moved quickly to get it repaired,” said Highways England project manager Karl Brooks.
“While we want to limit the impact that our work has on people’s journeys, these voids did need to be repaired with haste and we needed to ensure that there would be no more surprises. We have worked with our partners to minimise the impact this work has had, and are pleased that we are now able to fully re-open the M11 to traffic at Girton.”
The voids were fully excavated and backfilled with 1,200t of material. Sheet piling and additional drainage has also been installed to prevent the voids reforming.
