|Official name||Viadukt Jezerane|

|Total length||661 m|
|Longest span||40 m|

At this location the motorway route follows a horizontal curve of 900 metres (3,000 ft) radius. The viaduct is a beam structure across a series of spans averaging 36.1 metres (118 ft). The main span is 40 metres (130 ft) long. Due to its sheer size, the viaduct was designed in four segments comprising box girders and grillage systems and expansion joints atop three piers and both abutments. The piers comprise a box cross section, with 30 cm thick walls.
Traffic is regularly counted and reported by Hrvatske autoceste, operator of the viaduct and the A1 motorway where the structure is located, and published by Hrvatske ceste. Substantial variations between annual (AADT) and summer (ASDT) traffic volumes are attributed to the fact that the bridge carries substantial tourist traffic to the Adriatic resorts. The traffic count is performed using analysis of motorway toll ticket sales.
