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."

    A combination of technologies is leading to major congestion and cost reductions during roadworks on the UK’s motorway network. Innovative construction programme scheduling technology and the deployment of moveable barriers has achieved substantial savings of money and time on UK motorway roadworks managed by the Highways Agency (HA). This combination has set the scene for a new generation of road usage analysis tools. The HA’s objective was to reduce the congestion caused by lane closures during roa

    The UK Highways Agency is trialling a system to add commercially available traffic data to its existing sources to monitor how well traffic is flowing on England's motorways and strategic roads. Similar data sources are already used by satellite navigation devices, smartphones, and applications like Google maps. Better real-time data will allow agency staff to respond more quickly to incidents and identify delays and communicate them to drivers so they can take alternative routes if necessary.

    In a bid to reduce high levels of congestion on the Kwinana Freeway near Perth in Western Australia, the government is planning to introduce a smart motorway by converting the emergency stopping lane to a full-time running lane. The concept is similar to the smart motorways in use in the UK which use variable speed limits during busy times to manage congestion. The US$25 million (AU$47 million) project is expected to start in 2018-2019 and will also include: in-road detectors and full CCTV coverage to provi
