The presentation of the project for a suspended pedestrian bridge at Nečven – Trošenj across the Krka River

There are four bridges or crossings across the Krka River: at the entrance to the royal town of Knin, not far from its source below Krčić, over the Brljan Falls, where cherries bloom, at the Roški Cascades, where from ancient times a bridge joined the two

The banks of the Krka River will soon be joined in one more place, where almost four centuries ago, in the Candian War, the bridge that had connected the medieval fortresses of Nečven and Trošenj, some five hundred meters apart as a crow flies, was demolished. The bridge over the Krka canyon that will join these two fortresses will be 462.5 m long, and in terms of the length of the free-ranging load-bearing ropes it will be the second longest in Europe and in total length the third longest suspended pedestrian bridge in the world. The upper course of the Krka River deserves such an attraction. In addition to expanding the complex of pedestrian paths in the Krka National Park, the bridge will directly connect the municipality of Promina, on the left bank of the river, with the municipality of Kistanje, on the right bank, which will contribute to the economic development of this area.

“For many years now, the Krka National Park has invested in the visitor infrastructure for the middle and upper courses of the Krka, so as to encourage the development of the surrounding area through a sustainable visitor presence. The results of this are visible in many well organized features for visitors, as well as in statistical indicators of the number of visitors. I am certain this pedestrian bridge will be a crowning investment in projects that make this space attractive and encourage its development. It will represent a certain turnaround point, after which the development of the regions of Promina and Kistanje, as well as the towns of Drniš and Knin, and also the Ervenik municipality, will definitely experience a new tempo. However, in planning this project, particular attention was paid so as to not endanger the most valuable reasons why the Krka is protected as a national park the extraordinary natural features for which we care. So this bridge will represent a visitor attraction, with a fascinating view of the Krka Canyon and the Nečven and Trošenj fortresses, while not in any way burdening the underlying natural phenomena, as the project specifically negates directing visitors to the canyon itself, but rather focuses on keeping them on its edges. Additionally, through the formation of the Action Plan for Visitor Management, a model will be created that from the very beginning will ensure that this area, as a central attraction that will fully affirm the exceptional potential of the area gravitating to it, would not be not burdened by excessive visits”, was stated by the director of the Krka National Park, Krešimir Šakić, MA.

The bridge was designed to combine the functions of a walking path and a lookout point, and to offer a first-hand experience of the landscape and its untouched nature. To better fit into the landscape, the relatively lightweight structure of a suspended pedestrian bridge was suggested as the optimal solution. The engineers from the BLOK company have set forth the design of two portals and a pedestrian corridor suspended from supporting steel sprockets. The width of the pedestrian passage is to be 160 cm, which corresponds to the full width of a pedestrian path with two walking lanes.

“The proposed bridge solutions and their dimensions are based on a conceptual solution, which will need to be modified in accordance with the special conditions noted when carrying out the project. According to the load-bearing concept, steel wire hoists with a length of 462.5 would be suspended from 5 m high portals, with a vertical deflection in the middle of the sprocket of 20 m. The steel bearing wires are draped over the portal and are anchored in the anchoring blocks at a distance of 6 m behind each portal. The bearing assembly of the bridge, or the supporting sprockets, consists of 2 + 2 longitudinal ropes of high-grade steel with a cross-section of Ø 60 mm. The project calls for reinforced concrete portals covered with a stone surface, while steel portals would be required in special conditions. The pedestrian corridor in the middle of the bridge is 140 m above the Krka River”, noted Hrvoje Vukić, director of the BLOK d.o.o project office, clarifying the technical details of the bridge.

The construction of bridges is referred to in article 40 of the Spatial Plan of the Krka National Park. On the basis of the design and project, special conditions will be established by the relevant public institutions, along with environmental and nature protection specifications, following which a request for a spatial permit may be submitted. Given the special conditions, no lighting will be installed on the bridge. As an exception, it is permitted to place eco-friendly lighting in the zone of the entrance/exit portals, and bird distractors will also be installed. Tracing historical facts about the existence of a bridge at this place, where two rival Croatian noble dynasties, the Nelipić family in Nečven and the Šubić family in Trošanj, controlled the strategically important crossing over the river, the new bridge, as should be the case, will connect the two fortresses and present to visitors the valuable cultural and historical heritage along the Krka River from the Croatian medieval period. There are multiple advantages, as the large educational center – the Krka Eco Campus in Puljane will then be connected with the Center for the Interpretation of Nature, called “Krka – the Source of Life”, in Kistanje, where construction work is underway as part of the The Unknown Krka project.

“Each newly designed and accessible destination in the upper course of the Krka River, and especially this attractive project, will give visitors a new experience of intact nature. This project, along with the Krka Eco Campus in Puljane, offers the Promina municipality new potential for the development of rural tourism, for which it has been preparing for several years (construction of new and renovation of abandoned educational dry-stone lined roads and the renovation of former elementary school buildings in the immediate vicinity of the Krka National Park, as well as the adoption of spatial planning documentation in its jurisdiction The Third Amendments and Supplements to the Spatial Planning Documentaion of the Promina Municipality, adopted in 2018, envisages three tourist zones and the development of a Strategic Tourism Development Plan  the Interpretational Plan for the Cultural and Natural Heritage of the Promina municipality). Realization of this project will significantly extend the season of visists and increase the utilization of accommodation capacities: a total of one thousand beds are planned, of which five hundred are in the tourist zone and five hundred are in private accommodation outside it”, stated the head of the Promina Municipality, Tihomir Budanko.

The upper course of the river Krka has remained intact since the moment of the creation of its primordial beauty, so this is how we wish to present it to visitors who choose an active vacation in direct contact with nature. The suspension bridge will fill those who pass over it with a breath of adrenalin, but it will also revive the traditional service activities of the local population and launch new ones, which will improve the socio-economic and demographic features of this area.

“Projects aiming at the development of public tourist infrastructure elements in the upper course of the Krka National Park represent the basic conditions for a stronger development of tourism in our area. The projects that are currently being implemented on both sides of the Krka River, and specifically I refer to the construction of the Center for the Interpretation of Nature, the Krka The Source of Life in Kistanje, and the Krka Eco Campus in Puljane, along with the corresponding hiking trails and lookouts, will represent the cornerstone for development of the municipalities of Kistanje and Promina. The Suspended Pedestrian Bridge of Nečven - Trošenj will connect the areas on the left and right banks of the Krka River into a complete tourist destination, which will enable an increase in the number of visitors and hence opportunities for numerous agricultural firms and employers for employment and further job creation. Only with an increase in the growth of tourism along the Krka River we can expect new investments and employment, and consequently increase the standard of living of all citizens in our municipality and the neighboring municipalities”, noted the deputy mayor of the Kistanje municipality, Borislav Šarić.
