There are how many International highways in europe?

Answer 1

go and search

Answer 2

Many.
Many highways in Europe have a national and an international number.

Countries like Netherlands, Belgium and Luxembourg have as many international ones as ones that stay within the country.
Other countries, like Ireland, have less international border, so there will be fewer international highways.

To find the most important ones, take an internet map, like google maps, and zoom out till you just see the highway system.

Added:
Here is a link for Google maps: http://maps.google.co.uk/maps

You can zoom till you just see the highways with the E numbers for most of Europe, in the UK they have M numbers and Germany has numbers without letters for their own highways, but they also name the ones with E numbers.
I have seen many, I think all numbers up to 100 are used, and some have numbers like 232 or 804.
So my guess would be at least 150, maybe 200, and those are all motorways with several seperate lanes. Highways with just 2 lanes do not get European numbers.

Answer 3

There's a complete network of European Highways with "E"-numbers. There are Class A roads (reference and intermediate) as well as Class B roads (minor roads). Have a look at this article with maps - and, PLEASE, count yourself ;-)
