Progress visible in the field – Construction update S19 Krynice – Dobrzyniewo – Białystok Zachód

The S19 expressway on the Krynice – Dobrzyniewo – Białystok Zachód section is a key investment for the Podlasie region, carried out by a consortium of companies comprising PORR SA and Infrastructure Branch of Unibep SA, as part of the international transport corridor Via Carpatia. This strategic section will connect the north and south of Europe, supporting economic development and regional integration. Construction began in March 2024, and the completion is scheduled for the second quarter of 2026.

The complexity of the investment is especially evident where the route intersects with existing infrastructure — national roads, a railway line, and the Supraśl and Biała rivers. These are the sections that require precise safety measures and often the execution of works under partially maintained traffic. Another challenge lies in the variable ground conditions — the presence of non-load-bearing soils, a high groundwater level, and sections containing organic material. In response to these challenges, advanced geotechnical solutions have been implemented: vertical drains to accelerate consolidation, surcharge embankments, as well as foundations for bridge and engineering structures set on CFA piles and precast concrete piles — solutions tailored to the specific geology of the area.

Currently, over 200 people are working on the construction site — a team of engineers, operators, logistics staff, and specialists who ensure precision, safety, and quality in the tasks carried out every day. The organisation of work resembles the operation of a large mechanism — equipment, deliveries, schedule, and supervision must function in complete synchronisation.

“Daily telephone communication is so intense that the construction site is often compared to a call centre — except instead of headsets, there are helmets, and instead of desks, excavators and rollers,” says Sebastian Babiński, Construction Engineer.

The complexity of the project requires not only excellent planning but also a collaborative partnership between the contractor, investor, designer, and project supervision. The key is open communication, quick response to unforeseen situations, and shared responsibility for quality and timeliness. During the implementation phase, design adjustments were also made — based on local geotechnical assessments — which allowed for further optimisation of costs and technology.

The people involved in the construction of this section bring not only knowledge and experience but also personal pride and a sense of mission to the project. For many team members, this is more than just another construction project. It is the awareness that their work is creating infrastructure that genuinely changes the lives of thousands of people. As Sebastian Babiński highlights: “This is not just a route — it is infrastructure that will change the rhythm of life for thousands of people. We feel that we are leaving behind something lasting — something that truly matters.”
