This ambitious project, valued at approximately 130 million euros, seeks to transform one of the most congested road junctions in the Czech Republic, improving connectivity between Prague, Brno and Ostrava, as well as links to Slovakia and Hungary.
The D1 motorway, the region's transportation backbone, has suffered for decades from traffic pressures far exceeding its original capacity. Daily traffic jams, which at critical times can extend up to 20 kilometers, have generated a clamor for effective solutions. The response comes with a comprehensive modernization plan covering 30 kilometers of the D1, from Kývalka to Holubice, broken down into seven interconnected developments.
The project led by OHLA focuses on the crucial reconstruction of the links of Brno South and Brno Center, key points where traffic flow is compromised. In addition, the Kývalka interchange will be transformed into an all-way interchange, an improvement that promises to significantly optimize traffic flow. Other intersections will also undergo substantial improvements.
“This project represents a significant milestone for the Czech Republic’s infrastructure. We are committed to using our expertise and resources to improve the safety and efficiency of the D1 motorway, benefiting the millions of users who rely on it daily,” stated a representative of OHLA ŽS.
The works will not be limited to widening the roadway to six lanes; they also include the reconstruction of bridges, drainage systems, and the SOS emergency system. The demolition and reconstruction of overpasses, along with the implementation of advanced camera systems and real-time traffic control, guarantee a comprehensive improvement in road safety.
La sustainability and environmental protection are fundamental pillars of this project. New noise barriers will be installed, and an innovative road surface designed to significantly reduce noise pollution in nearby residential areas will be used. Furthermore, the use of recycled materials in construction will help minimize the project's carbon footprint.
"We are aware of the importance of minimizing the environmental impact of our works. The implementation of sustainable technologies and materials is a priority in this project," added a spokesperson for the consortium.
Construction is scheduled to begin in the fall of 2025, with a completion period of 840 days, plus an additional 180 days for final works. The project will be funded by the Czech Road and Motorway Authority (CZK 3.196.383.193) (approximately EUR 130.464.620), with support from state and municipal funds. European Union.
The fact that OHLA ŽS is headquartered in Brno adds special significance to this project, as the company strengthens its commitment to the local community. This project will improve residents' quality of life, reduce travel times and pollution, and increase road safety.
