Works to convert the M27 to a smart motorway will now not be completed until 2022 as Highways England works to implement new government guidance.

The upgrade to junctions 4 to 11 was originally supposed to be completed in March this year, promising quicker journey times for drivers.

Highways England says that it is making good progress with the scheme and now needs to install stopped vehicle detection technology before the works can be lifted.

The technology, currently in use on the M3 in Surrey, forms part of new Government guidance after a review into the safety of smart motorways.

By installing these radar sensors, it allows control room operators to be aware of stationary vehicles and put in place lane closures faster than through cameras alone.

If work continues to progress well, Highways England says it expects the M27 to be fully open in "Spring" 2022.
