The Krka Bridge is located in Croatia, between the Skradin and Šibenik interchanges. It is a 391 metres (1,283 ft) long concrete arch bridge spanning the Krka River at a height of 65 metres (213 ft). It carries the A1 motorway route south of Skradin, in immediate vicinity of Krka National Park.
The Krka River canyon is spanned by 204 metres (669 ft) reinforced concrete arch, with arch rise of 52 metres (171 ft). Composite spandrel structure consists of steel girders and reinforced concrete deck slab. The steel grillage consists of two main longitudinal girders at the axial distance of 7.6 metres (25 ft), transversal girders set 4 metres (13 ft) apart and peripheral beams. Immediately to the south of the bridge, there is Krka rest area offering a scenic view of the bridge and the river canyon.[1][2]
The construction works comprised 16,000 cubic meters of excavation, 2,000 cubic meters of embankments and backfill, 11,800 cubic meters of various types of concrete and 2,300 tons of reinforcement steel. That does not include additional 1,700 tons of steel used for execution of the spandrel structure.[3]
The Krka Bridge comprises the longest span of all the bridges on the A1 motorway, as its span surpasses the Maslenica Bridge by mere 4 m (13 ft).[1][3] That makes the Krka Bridge the fourth largest concrete arch bridge in Croatia, by span size, behind two arches of the Krk Bridge - 390 m (1,280 ft) and 244 m (801 ft) long and Šibenik Bridge (246 m (807 ft) long).[4][5][6][7]
