D4 Via Salis highway celebrates one year of operation with strong traffic and reliable service
One year after entering in operation, the D4 Via Salis highway has confirmed its positive impact on mobility between Central and South Bohemia. Since its opening, more than 5.3 million vehicles have used the route, benefiting from shorter travel times, improved driving comfort and uninterrupted service, with almost 99% availability and no unplanned closures.
Strong operational performance and service quality
The highway has reduced travel times by at least 20 minutes between Prague and Písek, while easing congestion on previously overloaded local roads crossing several municipalities.
Operational performance has been a key factor in this success. From the Operations Control Centre in Lety, Via Salis Operations teams monitor traffic in real time and coordinate all interventions, including roadside assistance, incident management, maintenance works and winter services. After twelve months of operation, the D4 has remained fully available to drivers, meeting its objective of safety, reliability and continuity of service.
Service quality has also been recognised beyond operational metrics. The D4 service area, developed in partnership with Shell, was awarded ‘Service Station of the Year’, thanks to its wide range of amenities, including diverse catering options, multiple fuel types and a children’s playground.
Public authorities highlight tangible results on the ground
“Thanks to the D4, traffic in our town has significantly eased over the past year, which is appreciated by all residents, especially families with children.” said Vladimír Vojáček, Mayor of Milín.
Petra Pecková, Governor of the Central Bohemian Region, also underlined that “The construction of the D4 highway has become an example of effective and cooperative communication with municipalities.”
A PPP model delivering over the long term
Delivered one month ahead of schedule by VINCI Construction CZ and awarded Construction Project of the Year, the D4 Via Salis highway is the first PPP highway project in the Czech Republic. Its first year of operation demonstrates the long-term relevance of the PPP model, from delivery to operation.
“This positive first year of operation demonstrates the strength of the PPP model not only to deliver major infrastructure projects, but also to operate them efficiently over the long term, in the interest of drivers and local communities.” declared Senka Jelenković, CEO of Via Salis.
