M25 upgraded to ‘smart’ motorway

Road users on the vast majority of the UK’s M25 will benefit from four-lane capacity now that the final section between junctions 25 and 27 has become a smart motorway. The road has been upgraded from three to four lanes in each direction, with the hard shoulder converted for use as a permanent traffic lane and enhanced on-road technology to manage traffic flow to improve the reliability of journey times, providing a boost for businesses and the wider economy.

Road users on the vast majority of the UK’s M25 will benefit from four-lane capacity now that the final section between junctions 25 and 27 has become a smart motorway. The road has been upgraded from three to four lanes in each direction, with the hard shoulder converted for use as a permanent traffic lane and enhanced on-road technology to manage traffic flow to improve the reliability of journey times, providing a boost for businesses and the wider economy.

The improvements on all sections of the M25 are part of a new generation of technology-driven improvements on the strategic road network known as ‘smart motorways’ with the permanent conversion of the hard shoulder for traffic, providing 24/7 extra capacity. The new infrastructure and technology that has been added between junctions 25 and 27 includes gantries spanning both carriageways, refuge areas, emergency telephones, overhead signals, verge-mounted signs and CCTV cameras.

Roads minister John Hayes said: “This upgrade is great news for 140,000 motorists who use this section of the M25 every day. It will mean smoother journeys, less congestion and provide a real boost to those businesses US$38 billion commitment to improve Britain’s roads by 2021 is helping to deliver a smarter motorway network that drives forward our economy and gets people to their destinations safely and on time.”

John Martin, 503 Highways Agency project manager said: “The new smart motorway will provide extra capacity and offer more reliable journeys. I would like to ask drivers to get smart and find out more about how to use it, the types of signs and signals they will see and what to do in the unlikely event of a breakdown."

    Plans to convert hundreds of miles of UK motorway hard shoulder into permanent driving lanes should be scrapped while major safety concerns exist, the Government’s Transport Committee has said. In 'all lane running', the latest version of smart motorways, the hard shoulder is used as a live lane of traffic. Previous schemes have only used the hard shoulder at peak times or to deal with congestion. The Committee did not agree with Government that this is an incremental change and a logical extension of
