M11 junction 11 to 12 northbound – drainage replacement work
We plan to carry out essential maintenance work to the drainage on the M11 northbound carriageway between junctions 11 and 12. Once complete, the road will be able to better disperse surface water.
We plan to complete this work over 3 nights between Monday 27 February and Wednesday 1 March, working between 9pm and 5am, weather permitting.
Closures and diversions
To carry out this work safely, we will need to close the M11 between junctions 11 and 12 and divert traffic, as detailed in the table below:
| Closure | Dates & Time | Diversion route |
| M11 junction 11 to 12 northbound closure | Monday 27 February to Wednesday 1 March, 9pm to 5am | Traffic will be diverted from the M11 at junction 11 onto the A10, A505, A1198 and the A603 before re-joining the M11 at junction 12
