The Idrijca Viadukt

The Bohinj Line enters the Idrijca Valley at Bača pri Modreju. Immediately after the Bača Tunnel, the train reaches the 258-meter-long Idrijca Viaduct, the longest viaduct on the entire line. At this part of the line, the railroad turns west towards the Most na Soči railway station, which is the main station for towns and villages in the Upper Soča Valley.

The viaduct starts with a stone section with seven arches, followed by a 51-meter-long iron structure on a stone pier, ending with another stone arch. During construction, fortresses were built at both ends of the viaduct, testifying to the important military function of the Bohinj Line in the past.
