Highways Agency plans to increase capacity of M4

The UK Highways Agency is holding a series of public exhibitions to inform road users, local residents and businesses about proposals to transform the M4 into one of the longest stretches of ‘smart motorway’ in England by 2021. The improvement, on a 32-mile stretch between junction 3 at Hayes in London, and junction 12 at Theale in Berkshire, would increase capacity, improve journey reliability and maintain safety.

The 1841 UK Highways Agency is holding a series of public exhibitions to inform road users, local residents and businesses about proposals to transform the M4 into one of the longest stretches of ‘smart motorway’ in England by 2021.

The improvement, on a 32-mile stretch between junction 3 at Hayes in London, and junction 12 at Theale in Berkshire, would increase capacity, improve journey reliability and maintain safety.

The proposals are part of the Government’s investment into England’s motorways and major A-roads, which will see up to US$6.7 billion a year pumped into improving the roads by 2021, underpinning economic growth and high quality jobs across the region.

As part of the proposals, there would be 64 miles of new traffic lane taken from the existing hard shoulder, increasing capacity.   The initial scheme design also includes 131 new gantries, with 32 existing gantries remaining, while eleven bridges would be rebuilt to provide space for the additional traffic lane and provide safe journeys over the M4 for decades to come. In addition, 32 refuge bays are proposed alongside the carriageway for use by drivers in an emergency.

Subject to gaining consent, construction would be carefully planned to be carried out in phases from 2016.

Lynne Stinson, Highways Agency project manager said: “The M4 is an important corridor in and out of London for those who live and work in Buckinghamshire and Berkshire, as well as those further afield in the South West and Wales, with around 130,000 vehicles using this stretch every day.

“Based on proven benefits elsewhere, we have produced outline proposals that would see 32 miles of the M4 transformed into a ‘smart motorway’; we’re planning extra capacity by converting the hard shoulder into an additional traffic lane and introducing variable mandatory speed limits displayed overhead to help smooth the flow of traffic and reduce congestion, and to provide traffic information, with safety bays in place to maintain safety.”

    The Institute of Advanced Motorists (IAM) has discovered that more than 40 per cent of all motorway and major A road lane closures in England in 2014 were caused by 185,457 vehicle breakdowns, 40,192 of which were in a ‘live lane’ i.e., a lane with other moving traffic around it vehicle breakdowns. The information came from a Freedom of Information (FOI) request from the IAM, which asked for the number of incidences of lane closures on roads managed by Highways England in 2014.

The contract will see WSP Parsons Brinkerhoff review sites along the M40 between junctions 3 and 8, which have been identified as areas where road noise is a particular issue and help decide where the barriers would be of benefit. Earlier this year, Highways England, working in partnership with the M40 Chiltern Environmental Group, (M40

    A pioneering bus scheme in Bristol will be more than doubled thanks to a huge US$41 million grant from the government, UK Transport Minister Baroness Kramer has announced. The MetroBus network uses dedicated busways to provide new express bus services into the city. The infrastructure will also boost existing bus services, which can use the busways to beat congestion. The new money will support the second phase of the Bristol MetroBus scheme and see the construction of another 3.1 miles of busways in th
