4. Previous rehabilitation of the bridge During the service life, the bridge has been rehabilitated and repaired more than 12 times due to numerous earthquakes, floods, war damage, decay due to deterioration etc. Construction practice has shown that stone bridges were most often demolished due to: underlined foundations, poor maintenance and increased traffic load. The largest number of damage to the main structural parts of the bridge and the demolition of bridges occurred during the First and Second World War. After the inspection and examination of the bridge in 1977, based on the registered large damage (due to poor maintenance, heavy traffic and adverse impacts of the accumulation of the HPP Bajina Basta), the Faculty of Civil Engineering in Belgrade prepared the Main Rehabilitation Design, where Professor Milan Gojkovic was a participant in this project. Rehabilitation design was divided into two phases: I - replacement of the pavement structure and new waterproofing, II - rehabilitation of the foundation of the river pillars. The project included the analysis and resolution of appropriate methods and measures for the protection of the foundations in the river bed due to the destructive impact of the river flow. Due to a lack of funds, repair works have not been done. Under the influence of the dam HPP Bajina Basta, built in 1966 downstream from the bridge, as well as HPP Visegrad which was built in 1989 at about 2 km upstream of the bridge, as well as irregularities in the Drina river bed, there were gradually increasing problems in the area of the foundations and arches of the bridge. The increase in erosion in the area of the foundation, especially in the rainy periods, under the influence of water overflows from the dam, as well as irregularities in the river bed, has been recorded especially the great impact on the state of the river Drina River has the discharge of the accumulation. 5.
