Some of the UK’s biggest motoring organisations have voiced concerns about opening up motorway hard shoulders to ease congestion. On April 14, an eight-mile stretch of the M25’s hard shoulder between junctions 23 and 25 was opened up to traffic. It’s all part of the Highways Agency’s ‘Smart Motorway All-Lane Running’ scheme and is designed to reduce congestion by increasing capacity on certain motorways. Under this scheme, the hard shoulder is used as a permanent running lane and only closed to traffic in the event of a road traffic incident. Roads affected use CCTV and electronic signs to monitor traffic flow and give early warning to drivers of incidents ahead. Similar schemes are run on sections of the M42, M1, M6 and M5, but the hard shoulder is only opened as a running lane during busy periods. This is known as Dynamic Hard Shoulder Running. Both the RAC and AA have raised concerns about what happens to motorists who breakdown on Smart stretches of motorway.
