Overview
Highways numbered from 1 to 7 radiate from the capital 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 highways 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 reason to upgrade all highways to motorways.
The motorway network totals 779 kilometres (484 mi) with additional 124 kilometres (77 mi) reserved only for motor traffic.
