The Highways Agency is starting initial work on an upgrade to the M25 between Kent and Surrey.
Two widening schemes on Britain's busiest motorway were completed today after three years of work.
Drivers on Britain's busiest motorway endured long delays today after a section of the road was shut following a two-lorry fatal accident.
Designers of a scheme to do away with the hard shoulder on parts of the M25 have hit back at critics. We revealed last month (above video) that the Highways Agency wants to let drivers use the shoulder as an extra lane to ease congestion.
The Association of British Drivers called it road-widening on the cheap and "an accident waiting to happen". This was Mike Pearse's report from May.
A man has died after the crane in which he was in fell onto the hard shoulder of the M25, Thames Valley Police have said.
The accident saw the anti-clockwise stretch between Junctions 15 and 16 closed off this morning, causing severe delays to commuters.
The road has since reopened, though one lane remains shut.
