The Črni Kal Viaduct is the longest and highest viaduct in Slovenia. It is located on the A1 motorway above the Osp Valley near the village of Gabrovica, about 20 km east of Koper. Its name means "Black Dale" in Slovene, after the depression it crosses.

The viaduct is 1065 metres long and is mounted on 11 columns, the highest reaching 87.5 m. Construction work began in 2001 and the viaduct was opened for traffic on September 23, 2004.[1] When almost completed in May 2004, it also served as a stage of the Giro d'Italia race.[2]
