National Highways – M11 junction 12 to 14

A message from National Highways: 

M11 junction 12 to 14 

Essential road marking refreshment works will be carried out on the M11 between junction 12 and 14. Once complete, drivers will benefit from a safer, and better-defined road surface. 


National Highways plan to complete this work over 4 weeks between Monday 23 May and Saturday 18 June. We will work between 9pm and 5am on weeknights only, weather conditions permitting. No work will take place during week beginning 30 May due to the bank holidays. 


Closures and diversions 

To carry out the work safely, the M11 will be closed between junctions 12 and 14 northbound from Monday 23 May to Saturday 28 June, then southbound from Monday 6 to Saturday 18 June. Traffic will be diverted as detailed below: 


Whilst the M11 is closed, drivers travelling northbound will be diverted from the M11 at junction 12 onto the A603, A1198, A428 and A14 to junction 32 before returning to the M11.  


Drivers travelling southbound will follow this diversion in reverse. 


A map of the diversion can be found below. Please click on the image to enlarge.


The drainage work will be continuing close by on the M11 northbound between junctions 12 and 13. This work is expected to be completed by Monday 30 May. Details of our planned weekend closures are as follows:

M11 junction 12 to 13 northbound closure and lane 2 southbound closure

  • Full weekend closure from 9pm on Friday 13 May to 6am on Monday 16 May
