The D4R7- Bratislava Bypass is a Public Private Partnership (PPP) project, defined as a long-term contract between a private party and a government entity. The contract consists of the design, construction, financing and operation of 27 km of the D4 motorway around Bratislava, Slovakia, as well as of 32 km of the R7 expressway. The new 27 km D4 motorway will create a bypass to the east of the city and a connection with the existing radial roads. The project also involves building the new 32-kilometre R7 radial expressway, running in a south-easterly direction from the city centre.
In May 2016, the Ministry of Transport, Construction and Regional Development of the Slovak Republic ( the Public Authority) signed with a project concessionaire - Zero Bypass Ltd., a concession agreement covering the design, construction, financing and operation of the southern part of the Bratislava Bypass. The bypass includes sections: D4 Jarovce – Ivanka north, D4 Ivanka north – Rača, R7 Prievoz – Ketelec, R7 Ketelec – Dunajská Lužná and R7 Dunajská Lužná – Holice. The new road infrastructure will provide increased transport capacity to the Slovak Capital and the neighbouring region, improving connectivity locally and internationally with enhanced safety and more reliable journey times.
The design and construction of the 27km motorway (D4) and 32km expressway was awarded to the D4R7 Construction s.r.o. consortium between Ferrovial Agroman and PORR.
