Project description
According to the Slovenian Government, represented by the Slovenian Motorway Association DARS, the Crni Kal viaduct, located between the Slovenian capital Ljubljana and Koper, is a landmark bridge. With a span of up to 140 m at the maximum height of 87.50 m, it is the biggest structure in Slovenia.
In 2004, the Klanec-Crni Kal section was opened to traffic. Two separate lane structures carry the traffic over the bridge, which rests on eleven pillars and has a length of 1’065 m. It was a design priority to give the pillars a very aesthetic form.
The construction project was implemented in order to minimize numerous traffic jams which occurred mostly during the summer months.
