Highways England was forced to close part of the M25 after two sinkholes were discovered during Monday night’s torrential storms.
The London ring road was closed at 11.30pm on Monday night after the sinkholes were discovered in the central reservation between Junction 4 (Orpington) and Junction 5 (Sevenoaks).
It is unclear what caused the sinkholes, however Highways England has confirmed that a “full repair” was carried out to rectify the problem before the road was reopened in the early hours of Tuesday morning.
The sinkholes were discovered following an accident on a nearby stretch of the motorway.
M25 sink hole
“Two large sink holes appeared overnight on Monday in the central reservation on the M25 between junctions 4 (Orpington) and 5 (Sevenoaks),” a Highways England spokesperson confirmed.
“The sink holes did not affect the road surface of the M25 but our assessment showed that we needed to close the M25 as a precaution while they were repaired.
“A full repair has now been completed, and we fully reopened the M25 in good time for Tuesday morning’s rush hour.”
Connect Plus Services (CPS) – made up of Balfour Beatty, Atkins and Egis Road Operation UK – operates and maintains the M25 motorway network, including all adjoining trunk and slip roads on behalf of Highways England.
Unlike Highways England’s other 11 regions, the M25 operates under a privately-financed design, build, finance & operate contract.
