Zečeve Drage Viaduct, Highway bridge in Gorski kotar, Croatia.

The Zečeve Drage Viaduct is a bridge crossing the mountainous Gorski kotar region with two parallel roadways spanning a significant distance. The structure uses tall supporting pillars positioned at intervals to bridge the uneven terrain and maintain a level surface for traffic.

The first roadway opened in 2004, with a second parallel structure added about four years later. This staged development improved traffic capacity through the challenging mountain region.

Traffic on the viaduct is measured by Autocesta Rijeka–Zagreb through motorway toll ticket sales, and Hrvatske ceste publishes the counts. Summer volumes far exceed the annual average because the A6 carries many tourists heading to Adriatic resorts. The viaduct is tolled within the A6 ticket system, with no separate toll plaza.

Vehicles cross the bridge as part of a toll motorway system without additional checkpoints at this location. Travelers should expect reduced visibility during fog or snow in the mountain environment.

The box girder, weighing 20,000 tonnes, was launched downhill because of the steep grade, with two VBT 19×140 cable stays acting as a braking mechanism. The girder and pier cross-sections are nearly identical to those of Bajer Bridge.
