Motorists using the motorway network near in and around north-east London are set to have their journeys disrupted due to a package of overnight closures that could last for almost a year, starting as early as next week.

A notice from National Highways in this week’s edition of the Guardian details the extent of the closures that will affect the M25, M11 and all associated slip and link roads.

The authority has made an order that will authorise the phased overnight closure of:

• The London-bound carriageway of the M11 between Junction 6 (M25 Junction 27) and Junction 4 (A406).

• The anti-clockwise carriageway of the M25 between Junction 30 (A13) and Junction 25 (A10).

• The clockwise carriageway of the M25 between Junction 26 (A121) and Junction 30 (A13).

• All slip and link roads leading to and from these lengths of carriageway.

The notice states the work is expected to last for 11 months starting on or after Monday and will involve barrier, carriageway, drainage, electrical, bridge inspections and other works.

The overnight closures will take place between (maximum periods): Mondays to Thursdays – 10pm to 5.30am; Fridays – 11pm to 6am; Saturdays – 10pm to 6am; Sundays – 10.30pm to 5.30am.

Traffic affected by the closures will be diverted via other junctions of the M11 and the M25 or by using the A10, A12, A104, A121, A127, A128 and the A406.
