Helsinki (Highways
2,
5 and
6 diverge from
1,
4 and
7, respectively), while highways
8 to 10 radiate from
Turku on the south-western coast of Finland. Highways
11 and
12 originate in
Tampere. The rest of the highways start from other major cities. Sections of highway between major cities have often been upgraded to
motorways, for example between Helsinki and
Tampere. Since Finland is a large and sparsely populated country, there is no need to upgrade all highways to motorways. ==Other roads==
