Kamačnik Bridge
Kamačnik Bridge is located between the Vrbovsko and Ravna Gora interchanges of the A6 motorway in Gorski Kotar, Croatia, spanning Kamačnik stream. It is long. The bridge was designed by Zlatko Šavor. It consists of two parallel structures, both completed in 2003 by Konstruktor. The bridge is tolled within the A6 motorway ticket system and there are no separate toll plazas associated with use of the bridge.
The bridge spans deep Kamačnik stream bridge canyon which is legally protected as a listed landscape.〔(【引用サイトリンク】 url= http://www.tz-vrbovsko.hr/kamacnik-eng.html )〕 This prevents any construction on the canyon cliffs and in turn requires an asymmetrical structure across a span of approximately .
