The D4 Motorway and R7 Expressway Project oversees the construction of the southern part of Bratislava Bypass and part of the southern expressway network, linking the west and the east part of Slovakia.

Projekt Diaľnice D4 a Rýchlostnej cesty R7 predpokladá vybudovanie južnej časti nultého obchvatu Bratislavy a časti južnej siete rýchlostných ciest spájajúcich západ a východ Slovenska.

The Bratislava Bypass PPP project
Motorway D4 & Expressway R7

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.

The most frequently used sector of the new D4 motorway will be the road connection Ivanka- sever – Čierna Voda. The outlook of future transport in this section  is 45,000 cars per day, including 1,500 trucks. The completing of D4/R7 in 2020 will immediately ease off the traffic heading towards the Pristavny bridge by about 15.11% for cars, and by 49.62 % during heavy traffic. In 2045, improvement of the individual traffic should reach 24.5% in comparison to the current situation (2016).


The new bridge crossing over the Danube river that will be a part of the Bratislava Bypass, will easily cope with 35,000 cars daily, and in both directions. A significant percentage of the overall amount will be the heavy traffic. The majority of trucks are expected to use the D4 section Podunajské Biskupice. On top of that, the section Rovinka – Podunajské Biskupice section is expected to absorb 28,000 cars,
and around 4,400 trucks each day.


Within the agreed PPP scheme, repayments for the D4R7 project will be significantly lower than previously expected, a reduction of almost 7%. Thanks to the positive situation on financial markets when closing the D4R7 contract between the Slovak republic and the concessionaire, the state has managed to decrease the interest rate of the D4R7 regular payoffs, making the PPP project even more favourable.


The entire length of the possible future Bratislava Bypass (consisting of the D4 motorway) is approximately 47km. The bypass would start at Jarovce – Kittsee, at the state border with Austria. It then continues towards Jarovce, Ivanka pri Dunaji and Stupava, until reaching the urban area of Devinska Nova Ves. Once the whole D4 motorway is completed, it will sustain a steady transport flow between Austria, Hungary, the Czech Republic and Poland, avoiding residential areas.  Currently, such transport runs through urban areas, using the D1 and D2 motorways.
