The Highways Agency said that all lanes of the motorway will re-open by Thursday morning foloowing work to stabilise the dene hole that appeared between junctions 5 and 6.
Simon Duke, Highways Agency Asset Delivery Manager for Kent said: “Our investigations are complete and the hole has been stabilised, meaning that traffic can safely use all lanes of the M2.
“The work tonight and tomorrow night will involve resurfacing lane two of the M2 in both directions following comprehensive geotechnical investigations.”
The hole is believed to be a dene hole – a historic man made hole which may have been used to mine for chalk hundreds of years ago.
The hole was filled in when the M2 was built but recent wet weather contributed to the destabilisation of the ground causing the hole to appear.
Around 40 tonnes of pea shingle has been used to stabilise the hole and further geotechnical investigations confirm that the ground beneath the M2 is safe for traffic to use.
