Mostogradnja is the leading Serbian bridge building company, with headquarters in Belgrade and daughter companies in Podgorica, Montenegro and Banjaluka, Bosnia and Herzegovina and a representative office in Moscow, Russia. Its projects have included bridges and interchanges, as well as industrial and military structures in former Yugoslavia and abroad.
In 1945, a group of engineers, technicians and workers at the Directorate of the Yugoslav Railways was given the task to reconstruct the railway bridge at Pančevo over Tamiš which was destroyed during World War II. In 1946 and 1947, the group was expanded and given additional responsibility to reconstruct the bridges over Tisa at Titel and over Danube at Bogojevo.
In July 1947, the Directorate of Yugoslav Railways established Mostogradnja Railway Civil Engineering Enterprise, to specialize in bridge construction. The headquarters of the company, which were formerly situated at various sites of large projects, were finally moved from Titel to Belgrade in early 1949.
In 1952, Mostogradnja separated from the public railway company and became an independent enterprise. During 1950s, Mostogradnja was expanded with the addition of the public railways' Enterprise For Repair of Construction Machines at Batajnica in 1955, and Pionir, another bridge construction enterprise from Belgrade in 1959.
In 1970s and 1980s, Mostogradnja completed a series of major construction projects in Yugoslavia and abroad. The projects at home included the Gazela bridge and Mostar and Autokomanda interchanges, several bridges over Danube, and the bridge connecting the island of Krk to the Croatian mainland, which at the time of construction featured the longest concrete arch in the world. Abroad, the company constructed bridges, hangars, reservoirs, aerials and various industrial and military structures in Europe, Asia and Africa. These included a series of bridges over Tigris and Euphrates in Iraq.
By early 1980s, Mostogradnja had 5,000 employees and was among world's top 250 construction companies. The decline of Yugoslavia and consequent United Nations trade embargo on Serbia in 1990s reduced the company's market, but it continued to build domestic projects, including the bridges over Sava at Obrenovac and Ostružnica. The previously socially-owned enterprise was privatized and became a joint stock company.
Company's recent projects have included the reconstruction of bridges destroyed by NATO during Kosovo war in 1999, as well as the repairs to numerous bridges across Serbia.
