Highways England M40/M42 Interchange Scheme – survey works from May 2021

In early May we’ll start the final phase of our overnight survey work to gather information which will inform the design of this vital interchange upgrade scheme.

We’ll be working:

•             between M42 junctions 3 and 3a from 4 May to 27 May

•             between M42 junction 3a and M40 junction 16 from 1 June to 17 June

•             between M42 junctions 3a and 4 from 18 June to 23 July

What are we doing?

We’ll carry out a number of different surveys on both carriageways. These will include drilling carriageway core samples, excavating small trial holes and ecology inspections.

We’ll work overnight, when the road is at its quietest.

How will the survey work affect motorists?

To safely carry out the surveys we’ll need to close some lanes, in 4km sections at a time, but will keep one lane open on each carriageway while we work (Monday to Saturday between 9pm and 6am). We’ll take a ‘traffic count’ before we close the lanes and if the traffic levels are too high, we’ll delay the work until they reduce.

All lanes will be open as usual during the daytime.

We’ll also need to close the following slip roads overnight:

•             M40 to M42 northbound link road from 14 June to 25 June

•             M42 junction 3a to M42 northbound link road from 28 June to 25 July

•             M42 to M40 southbound link road from 12 July to 20 July

We’ll put in place clearly signed diversion routes to the next junction when the slip roads are closed.

We apologise for any inconvenience this work may cause and advise everyone travelling through the area to allow extra time for journeys.

Please note these dates and times may be subject to change due to poor weather or for operational reasons.
