The construction cost for the Bosiljevo 2–Split (Dugopolje interchange) sector of the motorway was originally estimated by the government in 2001 and presented as "3 x 3 x 3" – that is, the 300 kilometers of the motorway was to be completed in 3 years at a cost of 3 billion marks (approximately 12.65 billion kuna at the time, or approximately 1.533 billion euros).
