D4R7 Project: A Key Road Infrastructure Development in Central Europe

The D4R7 project stands as one of the most significant road infrastructure developments in Central Europe. With over 59 km of new highways and expressways constructed around Bratislava, it has greatly enhanced mobility in the Slovak capital by easing urban traffic congestion and strengthening regional and international connections.

A Historic Change for Mobility in Bratislava

The completion of the D4R7 project has resulted in:

• Reduced congestion in the city center.
• Shorter travel times within the metropolitan area.

• Strengthened logistics networks between Slovakia and neighboring countries.

This development positions Bratislava as a strategic hub in European transportation routes.
