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 (UNECE). 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 (as defined by ECE/TRANS/SC.1/2016/3/Rev.1).
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 (examples: E18 and E6) 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.
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.[citation needed] 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.[citation needed] There were several minor revisions since, last in 2008 (as of 2009[update]).
The route numbering system is as follows:
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:
