D4 Highway Via Salis
Since 2021, VINCI Highways leds the consortium consisting in equal parts of VINCI and Meridiam (50/50) for the D4 highway linking Příbram (Central Bohemia) to Písek (South Bohemia) in Czech Republic.
This is the first public-private partnership (PPP) highway contract ever awarded in the country.
The project consists in designing, finance, build, operate and maintain a new 32 km highway and converting 17 km of existing infrastructure into a dual two-lane carriageway. The new highway will provide an improved road connection between rural South Bohemia and Prague, consequently fostering economic and social development, and will also contribute to improving traffic conditions on the country’s major commercial routes, particularly towards neighbouring Germany and Austria. The contract is for 28 years (including approximately 4 years of construction work) and represents an investment of some CZK 16.5 billion.
In January 2022, the project has won the prestigious international PFI (Project Finance International) Awards 2021 for the best European PPP (Public Private Partnership) project. The PFI Awards annually recognize the world’s most outstanding achievements in project finance.
A positive mobility opening opportunities
Innovation for efficiency
The project is distinguished by its focus on innovation and environmental sustainability. It will be carried out using a full BIM (Building Information Modelling) approach, a first in the country for a road construction project. The new highway will be equipped with state-of-the-art technologies that will, among other things, guarantee a high level of road safety and comfort for motorists and improve traffic conditions and traffic flow, thus reducing congestion and pollution.
A sustainable mobility
From an environmental standpoint, the project includes the recycling and reuse of up to 1.9 million cu. metres of excavated materials, as well as a commitment to recycle up to 60% of the total volume of asphalt mix. New storm water retention ponds, wildlife crossings and a “zero pesticide commitment” will contribute to preserving biodiversity.
