During these closures heavy steel beams will be lifted into place. This will enable construction of the new direct link from the M6 to the A14, as part of the Highways Agency’s £191 million junction improvement.
Highways Agency project manager Ivan Marriott said:
Linking the M6 and A14 will greatly improve the flow of traffic at Catthorpe junction, and work will be progressing over the coming months to create a new direct link underneath the M1 itself. These closures are necessary to allow our engineers to get large, heavy steel beams into place.
We have timed the work to take place overnight to cause the least amount of disruption – but drivers should plan their journeys and allow extra time while construction takes place.
We would like to thank road users for their continued patience while we deliver this important junction improvement.
The M1 northbound will be closed from the exit for the M6, northbound traffic will be diverted on to the M6 at junction 19, the A426, the A5 and the A4303 to re-join the M1 at junction 20.
Traffic traveling south on the M1 will be diverted from J20 taking the same diversion but in reverse.
Traffic traveling through to the A14 will be able to leave the M1 at J19 as usual.
The closures will take place between 9pm and 6am on 15, 16 and 17 September. A contingency closure for 18 September is planned in case the work over-runs, for example due to severe weather.
