From Tuesday 26 August, and for the following 15 consecutive nights, there will be overnight closures of various sections of the southbound carriageway between 10a and 13 while work is carried out on overhead gantries.
These will take place overnight at the following times:
- Monday to Thursday 10:00pm to 6:00am
- Friday 10:00pm to 8:00am
- Saturday 10:00pm to 10:00am
- Sunday 10:00pm to 5:30am.
During October there will be a further 12 full closures, either southbound or northbound, to install overhead signs.
There will be various rotating slip road closures at junction 12 every weekend in September and October, with an extended motorway closure of lane 1 from 10:00am to 12:00 noon on Sundays.
Highways Agency project manager David Cooke said:
Construction of this important scheme is progressing well. We have carried out much of the necessary work within the hard shoulder and verges of the motorway. We are now ready to install equipment on overhead gantries and to do this safely and quickly we need to close carriageways overnight.
We are also reconstructing and strengthening some of the carriageway. At junction 12 we will need to close slip roads over two weekends whilst we continue this work.
Once completed in 2015, the £102m smart motorway investment will make journey times more reliable and reduce congestion, by improving traffic flow using mandatory variable speed limits and giving road users more capacity on the motorway by using the hard shoulder as a permanent additional running lane.
