List of Interstate Highways

There are 65 primary Interstate Highways in the Interstate Highway System, a fictional network of freeways in the European continent. They are assigned one- or two-digit route numbers, whereas their associated "auxiliary" Interstate Highways receive three-digit route numbers. Typically, odd-numbered Interstates run south-north, with lower numbers in the west and higher numbers in the east; even-numbered Interstates run west-east, with lower numbers in the south and higher numbers in the north. Auxiliary highways have their numbering system where a different number prefixes the number of its parent highway.

Two route numbers are duplicated in the system, though the corresponding highways are separated by state lines which prevent confusion. The main list that discusses the primary Interstate Highways in the contiguous European continent is followed by sections regarding the islands of Corsica in France, and Sardinia in Italy.

European continent
There are 63 primary Interstate Highways listed in the table below.

Removed Interstates
This is a list of Interstate Highways that were originally signed when they were created, but these highways were removed to make way for new Interstate Highways. The main reasons for the removal is either the Interstate Highway System was expanding, or they had to be renumbered to fit the location and alignment.

Corsica
The Interstate Highways in the island of Corsica, France are signed with the standard Interstate Highway shield, with the letter "C-" prefixed before the number. There is only one freeway on the island near Ajaccio, the island's capital city.

Sardinia
The Interstate Highways in the island of Sardinia, Italy are signed with the standard Interstate Highway shield, with the letter "S-" prefixed before the number. Some sections are not in freeway-standards in some places.
