The work, which started at the end of January, has so far been able to be carried out using mainly narrow lanes and lane closures. Over the next two weeks there will need to be overnight access and slip road and carriageway closures.
Steve Davy, Highways Agency asset manager, said:
This work will improve the A14/M11 Girton interchange for road users. It has been very been carefully planned to minimise disruption to road users and that is why we have been able to carry out most of it using narrow lanes and lane closures.
For the final phase we will be completing the drainage repairs and resurfacing the carriageway and for that to be carried out safely for road users and roadworkers, we need some slip and access road closures, and closures of the southbound M11. These will all be overnight when traffic flows are lowest, but we do advise drivers affected by the closures to leave extra time for their journeys.
The closures will take place at different times over several locations at the Girton Interchange, as follows:
- the eastbound A14 slip road will be closed from tonight (Monday 17 March) for five nights from 9pm to 6am (access to the eastbound A1307 will be maintained)
- the access from M11 to the eastbound A14 will be closed from tonight (Monday 17 March) for five nights from 9pm to 6am
- the southbound M11 will be closed between junction 14 and 13 from Monday 24 March for two weeks, Monday to Friday only between 9pm and 6am
While the closures are in place, A14 traffic will be diverted via the A14, A1 and A428. Southbound M11 traffic will be diverted via the eastbound A14 and southbound A11.
The work is expected to complete on Friday 11 April.
