ROADWORKS to convert a stretch of the M6 into a smart motorway will enter a new phase next week, with the 50mph zone extending down to junction 17 for Sandbach.

Entering the new stage will require overnight closures between junction 18 for Middlewich and 17 for Sandbach, to install temporary narrow lanes and a 50mph speed limit.

The southbound stretch will be closed between 10pm and 6am from Monday, July 18 for four nights, with the northbound carriageway then closing for four nights from the following Monday, July 25.

Drivers will be able to follow clear diversions, with separate diversions for lorries to avoid a low bridge.

After the lifting of separate roadworks between Knutsford and junction 20 for Lymm last weekend, the total mileage affected will remain roughly the same.

Highways England is upgrading a 20-mile stretch between junction 19 for Knutsford and 16 for Crewe to smart motorway, with a view to saving commuters time in the future.

Smart motorways will allow four lanes of traffic, and clearer signs to advise motorists on traffic conditions.

Construction on the M6 in Cheshire began this February. Crews are tasked with digging up the old steel safety barrier in the central reservation, and digging foundations for a new concrete barrier.

Highways England Project Manager Kate Beirne said: “We’re determined to do all we can to minimise disruption while the smart motorway scheme is taking place, and will be keeping three lanes open during the daytime throughout the project.

“We’ll need to close a short stretch of the motorway for a few nights to install the temporary narrow lanes and 50mph speed limit between junctions 17 and 18, and have scheduled these closures to take place overnight when traffic levels are at their lowest.

“When the smart motorway goes live, drivers will benefit from an extra lane in each direction and variable speed limits will be used to keep traffic moving.”

A similar smart motorway scheme on a 15.5 mile stretch of the M62 in West Yorkshire, which was completed in 2013, has resulted in commuters saving up to 30 minutes each week.
