Three out of four lanes will be closed overnight from Wednesday 8 July on the anti-clockwise carriageway of the M25 between junction 26 for Waltham Abbey and junction 25 for Waltham Cross.
The closures are required to repair and strengthen an embankment following an earlier landslip in the area. The work will take place overnight Monday to Friday only until mid-September. Lanes will be closed from 10pm until 5.30am each night apart from Fridays when the lanes will close at 11pm.
