In 1960, in former Czechoslovakia, Dopravoprojekt was transformed into the National Institute for Design of Transport Related Structures with headquarters in Bratislava and branch offices in Prague and Brno. After forming the Czechoslovak Federation in 1969, the Institute was divided into three separate national design institutes. In July 1989, the National institute Dopravoprojekt had been transformed into a state-owned company. From May 1, 1992 Dopravoprojekt is an independent private joint stock company.

References - bridges and fly-overs • The “New Bridge” over the River Danube in Bratislava (Bridge SNP). • The “Lafranconi” Bridge over the River Danube in Bratislava. • The “Riverport” Bridge over the River Danube in Bratislava - adjoining flyovers. • The “Apollo” Bridge (Košická) over the River Danube in Bratislava. • The bridge over the River Danube in Medvedovo. • The bridge over the River Danube between Sturovo (Slovakia) and Ostrihom (Hungary). • Motorway viaduct at the village Podturen. • Motorway Flyover „Prievoz“ in Bratislava. • Viaducts in Žilina, Banská Bystrica, Bridge “Pustý hrad” over the River Hron at Zvolen and a number of other longspan motorway bridges at Liptov (Dovalovec, Bela, Hybica, Vychodna, Janosikova studnicka, etc.) Used software • Nexis (ESA-Prima Win) Motorway Bridge This project deals with increased effectiveness of external tendons, situated in a box girder by lifting them above bridge superstructure. By passing external tendons through a deviator above a bridge pier their uplift effectiveness increases, which enables to reduce substantially the section depth . This type tendons is called “extradosed” (ED). The advantages of this system, were utilized at designing 2 longspan bridges within the 9.7 km long section of the D1 motorway, running through Považská Bystrica (Slovakia). One of these bridges is the motorway Bridge over the River Vah at km 9.068. It carries the D1 motorway over the Váh River and the adjacent flooding area at the end of the motorway section “Sverepec – Vrtizer”. Motorway Bridge over River Vah in km 9.068
