The Korana is a river in central Croatia and west Bosnia and Herzegovina. The river has a total length of 138.6 km (86.1 mi) and watershed area of 2,301.5 km2 (888.6 sq mi).The river's name is derived from Proto-Indo-European *karr- 'rock'. It was recorded in the 13th century as Coranna and Corona.Korana rises in the eastern parts of Lika and creates the Plitvice Lakes, a UNESCO World Heritage Site. Downstream from Plitvice Lakes, the Korana river forms a 25 kilometers long border between Croatia and Bosnia and Herzegovina near Cazin. From there it flows northwards through Croatia, where it finally reaches the river Kupa at Karlovac. The soil of the karst region, through which this river flows consists of limestone. Under certain physical and chemical conditions the river is constantly creating new soil from plants (see: Plitvice Lakes). The river Slunjčica flows into Korana at Rastoke/Slunj, and the river Mrežnica flows into it at Karlovac. In the Korana exist rich molluscan assemblages composed of 33 species.

The Drežnik Viaduct is located in Karlovac, Croatia, immediately to the west of the Karlovac interchange on the A1 motorway. It is the longest viaduct in Croatia, spanning 2,485 metres (8,153 ft). It is executed in seven segments (225 m (738 ft)+270 m (890 ft)+4x408 m (1,339 ft)+358 m (1,175 ft) long), separated by expansion joints. The viaduct was constructed by Konstruktor, Split, as the main contractor, and Viadukt and Hidroelektra of Zagreb as subcontractors in 2000 and 2001.The viaduct is executed as two parallel structures, each 10.5 m (34 ft) wide. Their superstructures are continuous structures with spans of 35 metres (115 ft) to 70 metres (230 ft) m above Kupa River. The carriageway of each of the bridges consists of two traffic lanes 3.75 metres (12.3 ft) wide and two marginal strips 1 metre (3.3 ft) wide. There are no sidewalks and no emergency lanes on the bridge itself. The superstructure is executed in I-section prefabricated reinforced concrete girders, made monolithic with in situ executed transverse beams and the deck slab. The longitudinal girders are mostly of a uniform length (traversing 35 m (115 ft) spans), except for those spanning the river and the longest, 70 m (230 ft) long span. Foundations of the viaduct are executed on piles.Cost of the construction works related to the Drežnik Viaduct was 250 million Croatian kuna.The Drežnik Viaduct is the largest and the most significant structure on the Karlovac - Bosiljevo 1 section of the A1 motorway, which carries the transit traffic between Zagreb in the north and Rijeka and Split in the south, and channels it away from the Karlovac city centre, dramatically reducing travel times between those cities and relieving traffic congestion from the D1 state road running through Karlovac, which was especially severe during summer seasons.
