The Highways Agency has announced a series of overnight closures of both the M1 and M6 from today (Thursday).

The closures are in order to continue work on the new Catthorpe Viaduct which carries M6 southbound traffic over the M1 at junction 19.

The closures, which are all taking place overnight to minimise disruption, will be implemented as follows:

M1 southbound between the entry and exit slip roads at junction 19 on tonight (Thursday) from 9pm to 6am. A signed diversion will take traffic back onto the M1 southbound via junction 1 of the M6.

M1 northbound between the entry and exit slip roads at junction 19 tomorrow (Friday) from 10pm to 8am. A signed diversion will take traffic via junction 1 of the M6, before rejoining the M1 northbound via the A14 exit slip road.

M6 southbound between the exit slip road for the A14 and the M1 on the evening of Saturday from 8pm to 8am, and then for four nights from Monday 26 to Thursday 29 March from 9pm to 6am.

In both instances, M6 traffic for the M1 southbound will leave the M6 at junction 1, take the A426 and A5, joining the M1 at junction 18.

All the closures are to allow for removal of traffic management, and for white lining and studs work to take place. A series of contingency days are in place for each closure, and will be implemented if required.

Highways Agency project manager, Ivan Marriott said:

“These closures are essential for us to deliver the necessary work as quickly and as safely as possible. Diversion routes are in place, which are relatively short, and all work has been scheduled for overnight when traffic flows are reduced to help minimise the impact to road users.

“We advise motorists to be aware of these closures however, and to plan their journey accordingly.”

The scheme to replace the Catthorpe Viaduct started in July 2010, and is due to be complete by spring 2012.

Road users are advised to allow extra time for their journeys should they be using the junction while the overnight closures are in place. Road users can keep up to date and register for updates on the scheme website at
