International E-road network


The International E-road network is a numbering system for roads in Europe, Central Asia and Asia Minor, developed by the United Nations Economic Commission for Europe. The network is numbered from E1 up and signposted on a green background. Its roads cross national borders, consisting of three types of roads: highways, limited access roads, and ordinary roads.
The display of European roads on signs depend on jurisdiction. In most countries, the roads carry the European route designation alongside national designations. However, Belgium, Denmark, Norway and Sweden have integrated them as their sole route designations in most cases. Some places, such as the United Kingdom and Albania do not show the European designations at all.
Other continents have similar international road networks, e.g., the Pan-American Highway in the Americas, the Trans-African Highway network, and the Asian Highway Network.

History

UNECE was formed in 1947, and their first major act to improve transport was a joint UN declaration no. 1264, the Declaration on the Construction of Main International Traffic Arteries, signed in Geneva on 16 September 1950, which defined the first E-road network. Originally it was envisaged that the E-road network would be a highway system comparable to the US Interstate Highway System. The declaration was amended several times until 15 November 1975, when it was replaced by the European Agreement on Main International Traffic Arteries or "AGR", which set up a route numbering system and improved standards for roads in the list. The AGR last went through a major change in 1992 and in 2001 was extended into Central Asia to include the Caucasus nations. There were several minor revisions since, last in 2008.

Numbering system

The route numbering system is as follows:
  • Reference roads and intermediate roads, called Class-A roads, have numbers from 1 to 129.
  • *North–south routes have odd numbers; east–west routes have even numbers. The two main exceptions are E4 and E6, both north–south routes.
  • *The allocation of numbers progresses upwards from west to east and from north to south, with some exceptions.
  • Branch, link and connecting roads, called Class-B roads, have three-digit numbers above 130.
  • Reference roads are roads numbered 5–95 ending with 0 or 5 or having odd numbers 101–129. They generally go across Europe and are usually several thousand kilometres long.
  • * North–south reference roads have numbers that end with the digit 5 from 5 to 95, or odd numbers from 101 to 129, increasing from west to east.
  • * East-west reference roads have two-digit numbers that end with the digit 0, increasing from north to south.
  • Intermediate roads are roads numbered 1 to 99 that are not reference roads. They are usually considerably shorter than the reference roads. They have numbers between those of the reference roads between which they are located. Like reference roads, north–south intermediate roads have odd numbers; east–west roads have even numbers.
  • Class-B roads have three-digit numbers: the first digit is that of the nearest reference road to the north, the second digit is that of the nearest reference road to the west, and the third digit is a serial number.
  • North–south Class-A roads located eastwards of road E99 have three-digit odd numbers from 101 to 129. Other rules for Class-A roads above apply to these roads.
  • Class-B roads located eastwards of E101 have 3-digit numbers beginning with 0, from 001 to 099.

Exceptions

In the first established and approved version, the road numbers were well ordered. Since then a number of exceptions to this principle have been allowed.
Two Class-A roads, E6 and E4 were originally scheduled to be renamed into E47 and E55, respectively. However, since Sweden and Norway have integrated the E-roads into their national networks, signposted as E6 and E4 throughout, a decision was made to keep the pre-1992 numbers for the roads in those two countries. These exceptions were granted because of the excessive expense connected with re-signing not only the long routes themselves, but also the associated road network in the area. The new numbers are, however, used from Denmark and southward, though, as do other European routes within Scandinavia. These two roads are the most conspicuous exceptions to the rule that even numbers signify west–east E-roads.
Further exceptions are:
These irregularities exist just because it is hard to maintain good order when extending the network, and the UNECE want to avoid changing road numbers.
Because the Socialist People's Republic of Albania refused to participate in international treaties such as the AGR, it was conspicuously excluded from the route scheme, with E65 and E90 making noticeable detours to go around it. In the 1990s, Albania opened up to the rest of Europe, but only ratified the AGR in August 2006, so its integration into the E-road network remains weak.

Signage

Where the European routes are signed, green signs with white numbers are used.
There are different strategies for determining how frequently to signpost the roads.
  • Sweden, Norway and Denmark have integrated the E-road numbers into their networks, meaning that the roads usually have no other national number.
  • In Belgium, E-numbers are traditionally associated with highways, even though other grade E-roads pass through the country. As a result, the E-number is signposted only on the highway portions of the E-road network, while for non-motorways only the national number is shown. On the highway portions of the E-network, the E-numbers are the standard and thus referred to in news bulletins rather than the national number. Serbia and Italy have a similar principle.
  • In most countries the E-roads form a network on top of the national network. The green signs are frequent enough to show how to follow the roads, but do not usually show how to reach them.
  • In some countries, like Croatia, Bulgaria and Albania, E-roads are well signposted, but they sometimes follow older routes instead of highways.
  • In some countries, like Germany, Italy and Greece, E-roads are signposted only on motorways and main road itineraries.
  • In Ireland the signposting of E-roads is specified in Chapter 2 of the 2010 Traffic Signs Manual published by the Department of Transport, and specifies that E-roads are to be signed on route confirmation signs only. The first E-road numbers were signed in July 2007 on the N11 bypass in Gorey. Since then they have gradually spread across the E-road network in Ireland.
  • In a few European countries such as the United Kingdom, Albania, and many Asian countries such as Uzbekistan, the E-roads are not signposted at all.

Road design standards

The following design standards should be applied to Euroroutes unless there are exceptional circumstances :
  • Built-up areas shall be by-passed if they constitute a hindrance or a danger.
  • The roads should preferably be highways or express roads.
  • They should be homogeneous and be designed for at least . The highways should be at least.
  • Gradients should not exceed 8% on roads designed for, decreasing to 4% on roads designed for traffic.
  • The radius of curved sections of road should be a minimum of on roads designed for rising to on roads designed for.
  • "Stopping distance visibility" should be at least on roads designed for, rising to on roads designed for.
  • Lane width should be at least on straight sections of road. This guarantees adequate clearance for any vehicle having a superstructure of width which is the maximum specified width in Directive 2002/7/EC of the European Parliament and of the Council which recognize some specific tolerances for some specific countries.
  • The shoulder is recommended to be at least on ordinary roads and on highways.
  • Central reservations should be at least unless there is a barrier between the two carriageways.
  • Overhead clearance should be not less than.
  • Railway intersections should be at different levels.
These requirements are meant to be followed for road construction. When new E-roads have been added these requirements have not been followed stringently. For example, the E45 in Sweden, added in 2006, has long parts with width or the E22 in eastern Europe forcing drivers to slow down to by taking the route through villages. In Norway, parts of the E10 are wide and in Central Asia even some gravel roads have been included.

Cultural significance

In Belgium, for example, motorway E-numbers have taken on the same kind of persistent cultural integration and significance as M-numbers in the UK, or Interstate numbers in the United States. Local businesses will refer to, or even incorporate the road designator in their business name. The annual road cycling race "E3 Harelbeke" takes part of its name from the former E3. The same applies to the retail chain "E5-mode" that started with shops easily accessible from the former E5.
In Sweden, the ice hockey games between HV71 from Jönköping and Linköping HC from Linköping have come to be called "the E4-derby". It's about 130 km between the cities, and they are situated in different provinces and counties, so the "derby" denomination is really far fetched, and it's often joked about that HV71's meetings with the teams from Stockholm or even as far north as Luleå would be an "E4 derby" just as much.
In Norway, the band D.D.E. released a song named after E6.
