The Srijane Vidauct, also known as Radovići Viaduct, is located between the Bisko and Blato na Cetini interchanges of the A1 motorway in Croatia. It is 504 metres (1,654 ft) long plate girder reinforced concrete viaduct. At this location the motorway route follows a horizontal curve of 850 metres (2,790 ft) radius. The viaduct comprises 13 spans. The viaduct and its approach embankments traverse a 1,500 metres (4,900 ft) long valley. The viaduct is executed as two parallel structures, and each of the structures is 13.95 metres (45.8 ft) wide.
The viaduct was completed in 2007, and it represents the most significant structure on Dugopolje–Šestanovac section of the A1 motorway.
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.
