International
European Road Network
 The
International European Road Network, otherwise known as Euroroutes or E-Roads, is an international network of
major routes across Europe.
The network was established in 1975 by the United
Nations Economic Commission for Europe (UNECE), and was designed to create a
network of international roads of strategic importance. It was aimed at the
promotion of the road network for cross-European journeys, particularly for
business and freight.
Signs
 Signs started to appear on the
routes in some countries within 5 years, featuring the new Euroroute designations.
The Euroroutes
themselves
are signposted using a small green plate featuring the route number. However
the practise of identifying the roads is only operation in some countries.
Most
European countries use the Euroroute system on top of their own national road network,
with intermittent signage to advise drivers they are still on the same road. The
roads are not comprehensively signposted from other areas and roads.
However,
in Belgium, Sweden, Norway and Denmark, Euroroutes have been integrated into the
national road network, having taken the place of the original route
designations.
The UK and Ireland that don't
display the Euroroutes on signs, and in Germany the numbers
rarely feature on signage.
The numbering
system
The route system
introduced by UNECE in 1975 underwent a significant overhaul in 1992:
(source: UNECE)
- The main Reference
and Intermediate roads (Class-A) are indicated by their two-digit number
designation. Branch, link and connecting roads (Class-B), have
three-digit numbers.
- In general:
- North-south
reference roads have two-digit odd numbers terminating in the figure 5
and increasing from west to east.
- East-west
reference roads have two-digit even numbers terminating in the figure 0
and increasing from north to south.
- Intermediate
roads have two-digit odd (north-south) and two-digit even (west-east)
numbers between the numbers of the reference roads between which they
are located.
- Class-B roads
have three-digit numbers, the first digit being that of the nearest
reference road to the north, the second digit being that of the nearest
reference road to the west, and the third digit being a serial number.
- North-south Class-A
roads located eastwards of road E99 have three-digit odd numbers from 101 to
129. Other rules mentioned in paragraph 2 above apply to theseroads.
- Class-B roads
located eastwards of E101 have 3-digit numbers, beginning with 0, from 001
to 099.
There are some
exceptions to this numbering system, just like in the UK (for example A42),
namely due to a lack of available numbers in the correct group.
