Bridge Dr. Franjo Tudjman in Dubrovnik
The bridge named Dr. Franjo Tudjman is situated on the north-west zone of Dubrovnik, near the international maritime passenger and tourist port of the city of Dubrovnik “Luka Gruz” and the main bus terminal, and it is a part of the main approaching road towards the city, therefore it is one of the landmarks of Dubrovnik the most tourists see the first. It is a cable-stayed bridge carrying the main state road at the western approach to Dubrovnik, across the river Rijeka Dubrovacka. The original bridge design was developed in 1989, however, construction was stopped at the onset of the Croatian War of Independence, and in 2002 it was finalized.
Croatian company “Hrvatske ceste” (operator of the Croatian state roads) agreed with The City of Dubrovnik to make this bridge more appealing during night, by ordering a an architectural light design project.
The Light design project made by Nova-lux started with creating a light design concept that will accentuate the structure of the bridge, which is very specific due to one A-shaped pylon design. The A-shaped pylon 141.5 m tall (measured from the top surface of the foundations) and supports structure on the cable-stayed portion of the bridge consists of a composite girder and the cable stays. Thy pylon is lit from two levels, creating a powerful visual effect while approaching and passing over the bridge. Angled 38 cable stays are individually lit with powerful light fixtures with narrow beam aimed towards the top of the pylon. The horizontal structure of the bridge, 518 metres long measured between the abutments, is accentuated with dynamic RGB line of light, and it is not visible to drivers on the bridge in order to drivers not to be distructed. The structure under the deck (overall span of the girder is 325 m,) is lit only slightly, in order to create a 3D effect of the bridge. Various lighting scenes are defined also by light designers and engineers in Nova-lux company, some of them can be seen on 3D visualizations.
The implementation of this project is in the tender phase.
