Structure description
At this location the motorway route follows a horizontal curve of 2006 metres (6,581.4 ft) radius. Transversal grade of the deck is constant and equal to 2.5%, while elevation grade of the bridge is constant at 0.835%, sloping down towards Oštrovica. The bridge is a box girder structure supporting the deck across 10 spans: 42.63 m (139.9 ft) + 8 x 50.16 m (164.6 ft) + 42.63 m (139.9 ft). Since the elevation of the bridge lies 41 metres (134.5 ft) above the average water level of Lake Bajer, incremental launching of the bridge was executed without use of any auxiliary piers. The main longitudinal girders comprise box cross-section and were divided in 19 sections each (2 x 27.94 m (91.7 ft) + 15 x 25.08 m (82.3 ft) + 2 x 27.94 m (91.7 ft)). Piers of the bridge comprise a 6.6 metres (21.7 ft) by 3.1 metres (10.2 ft) box cross-section with 30 centimetres (11.8 in) thick walls. Bridge abutments and shore piers have shallow foundations, while those piers located within the lake have foundations executed on groups of six piles each. The piles are circular in cross section, 1.5 metres (4.9 ft) in diameter, and are connected with beam cap slabs measuring 8.5 m (27.9 ft) x 9.5 m (31.2 ft) x 2.5 m (8.2 ft).Traffic volume
