S/S BRIDGES AND VIADUCTS 2017

LIMSKA DRAGA VIADUCT The Lim Channel bay cuts deep into the mainland along the Limska Draga valley and extends for a length of 9 km, all the way to the City of Pazin. Around the 4th kilometre from the end of the bay, the A9 Highway (used to be State Road No. 21) crosses the valley on its viaduct that is 552 m long and rises 125 m above the valley floor. The viaduct is harmoniously incorporated into the landscaping ambiance and it can be considered a tourist attraction. Even more so because of the proximity of the ruins of the old City of Dvigrad. The remains of the city date all the way back to the Roman times, perhaps even prior to that. The Lim Channel is also known for its rich gastronomy offer featured in several high category restaurants. The viaduct was completed after 30 months of construction and opened for traffic in June 1991. The bridge was designed by IPZ Zagreb, and the responsible designer-author was Ivan Dumbović, B.Sc.Eng. (1936-2016). The viaduct is a girder type bridge with a steel box-shaped cross section superstructure with 80+100+160+100+80 m spans. It rests on 4 reinforced concrete pillars 38, 46, 80 and 96 m in height on a shallow rock base. The total width of the viaduct is 12.1 m with the roadway taking up 7.1 m. During the construction of the superstructure, 7,100 m3 of concrete, 950 tons of armature and 2,400 tons of steel were used. The viaduct was constructed by the construction company Viadukt from Zagreb (concrete works), Đuro Đaković from Slavonski Brod (assembly) and the steel construction was delivered by Goša from Smederevska Palanka. The facility is managed by the company Bina Istra d.d. Future plans, as a part of the A9 Highway construction, up to the full profile, call for a parallel second roadway construction. In order to experience the Limska Draga viaduct in all its beauty and magnitude, you should take the side road from Kanfar in the direction of the ruins of Dvigrad, and then walk a kilometre or two to the base of the viaduct.
