The M25 will become the 'smartest' motorway in the country.
Two sections of the motorway, opening this month and next, will have the hard shoulder converted into another lane for drivers to use as well as new technology that will manage traffic flow, improving the reliability of journey times.
One section is between Junction 5 and 6/7 on the Kent and Surrey border whilst the other is in Hertfordshire.
The improvements are part of a new, technology-driven generation known as 'smart motorways'.
John Martin, Highways Agency Senior Project Manager said, "Around £1.7 billion is being invested into roads in the South East by 2021.
"Most of the work to improve journeys on these stretches in Hertfordshire and Kent/Surrey is complete and we are now testing the new technology."
Drivers will be able to use the new motorway to its full potential later this year.
The Highways Agency will start resurfacing roads in Kent on Wednesday to provide smoother and safer journeys for motorists.
The overnight resurfacing is taking place between junction 4 in Orpington and junction 5 in Sevenoaks.
Sections of the carriageway will be resurfaced and the white lines and road studs renewed.
Weather permitting, the work will be completed by Friday 2th May.
The new surface and cats eyes will provide smoother and safer journeys for the many drivers that rely on this busy route. We have planned to carry out the work overnight, when we know traffic flows are lowest, to minimise disruption.”
The work will be carried out overnight between 10pm and 5.30am, Monday to Thursday, and between 11pm and 6am on Friday nights.
