M25 Junctions 27 to 30 Widening

The north-eastern quadrant of the M25 has involved widening 17 miles of the motorway between the M11 and Thurrock. The last section of works required close interface with the Dartford Crossing to avoid elongated periods of delay for the travelling public; an enhanced vehicle recovery regime was implemented during this phase of the works.

The widening construction works naturally required a stringent safety strategy due to the close proximity of road workers, plant and site vehicles to the live network and within the limited space of the hard shoulder. At its peak the project had over 2,000 staff on site every month. These risks were carefully managed through risk assessments and effective controls.
