Severe delays are expected overnight as M25 traffic is set to be diverted via the M11 due to uncompleted verge works.
Commuters travelling clockwise towards junction 26 will be diverted off of the motorway between 10pm and 5.30am at the Waltham Abbey slip road via junction 7 for the M11.
Traffic will then rejoin the carriageway at Waltham Cross due to uncompleted work between Bell Common Tunnel and junction 27.
The Highways Agency has confirmed that estimated delays of over 15 minutes will be ongoing until Monday.
The estimated cost for the works, that are expected to finish at the end of the month, is £188m and will include new signage and lighting.
