Notable Structures
The southernmost section of the motorway, between the Jankomir and Zaprešić interchanges, forms part of the Zagreb bypass and entails a number of viaducts spanning roads and railways, including a 373-metre (1,224 ft) viaduct across the Zagreb–Ljubljana railway. Furthermore, the section comprises the Sava River Bridge, spanning 1,072 metres (3,517 ft). All the structures along the section are executed as dual structures with four traffic lanes.
The northernmost segment between the Krapina interchange and the Macelj border crossing traverses rugged terrain, requiring further viaducts and tunnels. Among those, the most notable ones are the 579-metre (1,900 ft) Krapinčica Viaduct and the 1,740-metre (5,710 ft) Sveta Tri Kralja Tunnel. The tunnel is part of a sequence of two tunnels and three viaducts in a 3.7-kilometre (2.3 mi) segment between Krapina and Đurmanec. Generally, the Krapina–Macelj border crossing segment of the A2 motorway required numerous expensive engineering works, including six tunnels and nine viaducts, which caused the construction cost to be over 235 million euros.

Famous quotes containing the words notable and/or structures:
“Every notable advance in technique or organization has to be paid for, and in most cases the debit is more or less equivalent to the credit. Except of course when it’s more than equivalent, as it has been with universal education, for example, or wireless, or these damned aeroplanes. In which case, of course, your progress is a step backwards and downwards.”
—Aldous Huxley (1894–1963)
“If there are people who feel that God wants them to change the structures of society, that is something between them and their God. We must serve him in whatever way we are called. I am called to help the individual; to love each poor person. Not to deal with institutions. I am in no position to judge.”
—Mother Teresa (b. 1910)
