Planning service area locations

Services can be lost within in some awkward junctions.

Some of the most famous (and indeed infamous) motorway services in the country are positioned at difficult roundabouts. The blame for this varies depending on when they were built.

Until 1992, motorway service area locations were chosen by the government. There was no rule that they had to be built online, but they usually were. They were planned at intervals roughly every 15 miles (skipping every other service area on a quiet road). The precise location would be studied in detail, considering how much disturbance would be caused and how pleasant a site it would make.

As services became larger and motorways became less popular, planning services became more of an art. Motorways were opening around the rural-urban fringe where there were frequent junctions and plenty of irate neighbours. In addition, developers were falling out of love with the whole idea, so the government tried to keep them sweet by choosing profitable locations. These factors all combined to cause many motorways like the M25 and M42 to open without enough services, and to cause services to be proposed in totally unsuitable locations such as Gordano, South Mimms, Tamworth and Birchanger Green, which are all offline services. Like many Department for Transport bodge jobs, these junctions have gone on to cause a headache for Highways England.

By 1992, developers were totally responsible for planning service area locations. Developers favoured profitable locations at existing junctions, and the proposal was supposed to encourage more frequent, smaller services. A minimum distance of 15 miles was specified.

In 2013, the absolute minimum distance was abolished. Two rival service stations can in theory now be built opposite each other, if they can both get planning approval.

On A-roads, planning services has always been down to the private sector, with no joined-up planning process.

In Ireland, online services are planned by the state while offline services are planned by the private sector.

Areas With No Services

Over time, the planning system has resulted in some significant lengths of motorway having no services. Government guidance has generally been to keep services no more than 28 miles apart on any motorway route, but there have been some notable exceptions:

  • There was a famous sign on the M4 westbound approaching Heston, which said "last services for 106 m". This was measured to Aust, but the motorway wasn't complete at the time. It was later changed to 82 miles, and remained that way for a while as there was a debate about what to do in the Reading area.
  • The M42 acts as a link road between several key motorways: the M5, M6, M40 and ultimately the M1. While some services were eventually provided on the road, the core section between the M40 and M6 remains without any. This creates a 48 mile gap between Warwick and Hilton Park - though there is an alternative route with more services. Services in the Solihull area were debated before the road was built and continue to be debated to this day.
  • When the M25 was a rushed job and in many respects it wasn't well planned. When it was completed in 1986, it had just one half-built service area covering the whole 118 mile route. The gap was never truly plugged until Cobham opened in 2012.
  • The M40 was completed in 1991. Linking the M25 and the M42, it combined both of the problems above into one mega-problem. It was now possible to drive from Maidstone to Telford, a journey of about 200 miles, without passing any services at all. This issue received political attention, as it was used to justify deregulating the industry. Cherwell Valley opened in 1994, with Beaconsfield filling the final gap on the M40 in 2009.
  • The A1(M) through North Yorkshire is the only significant length of motorway to open since the government stopped planning motorway services, with the first phase opening in 2009. As it is an upgrade to the existing A1, its construction involved actively taking away existing facilities. Local objections mean the planning system has been slow to replace them: it is 63 miles from Barnsdale Bar to Scotch Corner, with only Wetherby, and Leeming Bar and Ferrybridge (both of which require a diversion) in between.

Closest Services

Lymm and Knutsford on the M6, which are 5.1 miles apart (or 6.3 including the junction). If you disqualify Lymm for being a truckstop, then the answer will be at the far end of the M4: Pont Abraham and Swansea are 6.2 miles apart (or 6.7 including the roundabouts).

There are many examples of signposted A-road services which are only one mile apart, such as Solstice and Countess on the A303, or Birchanger Green and Stansted on the A120.
