The Djurdjevica Tara Bridge is a road bridge in the north of Montenegro. The curved in plan building has two lanes. It is approximately 25 kilometers by road east of Zabljak between the villages Budečevica and Tresnjica at an altitude of about 780 meters ( road ) above sea level and spans at the narrowest point in a maximum height of 150 meters, the canyon of the river Tara. It is named after the bridge immediately north village Djurdjevica Tara.

History

The bridge was built from 1938 to plans by Mijat S. Trojanović and opened to traffic in November 1940. The building was one of Europe's largest reinforced concrete arch bridges for road traffic. In spring 1942, partisans blew up an arch of the bridge in 1946 was followed by the reconstruction.

Construction

The approximately 350 meters long and 7 meters wide arch bridge is a reinforced concrete structure. It has in the main opening onto a 116 meter wide span reinforced concrete arch, to the west join, on the left side of the river four arches with Pfeilerachsabständen of each 47 meters.

The main arch was created on a falsework, which was supported by two wooden scaffold towers with heights of around 100 meters and 141 meters. The design for the falsework construction came from the Swiss master carpenter Richard Coray. It was trimmed with 650 cubic meters of spruce wood with an ax by hand to timber produced within six months. As wood joints bolts were used.

6 meters wide main arc has a cross section consisting of two external parallel concrete arch ribs, which are connected to each other at half the cross-sectional height of a plate and the plate by means of transverse bars. The preparation was carried out in three sections. First, the ribs together with the transverse bar has been cemented to the lower edge of the plate, and then followed by the plate, and finally the upper part of the sheet ribs. Thus, the previous concreting sections were used for removal of the loads and the falsework did not have to be dimensioned for the full bow weight.
