The bridge has three carriageways of the total width 11 m, and two footways 1.70 m wide each.
This bridge is a representative workmanship of the Yugoslav civil engineering. The entire structure of the bridge was determined by the heigh right hand bank and 51.5 m lower water flooded left and bank of the Danube. In order to overcome a great difference of levels, the bridge was designed in one direction longitudinal inclination of 2.3% which is the greatest inclination on the whole highway. The bridge structure is divided in the main structure spanning the Danube and eight approach structures, one being on the right and seven on the left river bank. The main structure is the continuous girder over three spans 105 + 210 + 105 m with overhangs of 15 m on both sides. Box cross-section with two vertical webs is stiffened at every 9.00 m by cross frames.
The cross section height ranges from 6.00 m in the centre of the main span to 11.00 m above its supports. The web thickness and the bottom slab thickness varies, depending on the static needs.
§ The bridge founding was done on 7 riparian structures on the left bank and one approach structure on the right bank with the use of Franci piles.
§ The main structure columns were founded in different ways:
- river piers on caissons;
- the pier towards the left bank on Franci piles dia. 50 cm;
- the pier towards the right bank on the drilled piles system HW dia. 150 cm.
§ The main structure was constructed without scaffold applying gradual concrete casting with the cantilever method. 'The technology of cantilever method of building was for the first time used for the span of 210 m, with us and in the world. All cross section elements were performed with permanent tightening of the carrying cables according to the stakes of work.
§ The bridge was bombed twice and partly destroyed during NATO bombardment on April 1st and April 21st, 1999, but it was temporarily fixed soon after the bombing was over and reopened on July 19, 1999, as it is an important part of the E75. It is currently being properly reconstructed, but because of its vital significance for the traffic, it is not closed. Since then it is under construction. Contractor is austrian company "Alpine"
