# Poland Builds Nation's Tallest Viaduct on S19 Expressway Engineering marvel in Podkarpacie region reaches 80-meter heights using advanced cantilever construction methods. - **Source:** [Interia Fakty](https://fakty.interia.pl) - **Published:** 2026-11-07 - **Topic:** [Business](https://brifing.si/c/business) - **Original article:** - **On Brifing:** https://brifing.si/s/bffb4c5d-20a2-4b7c-8da4-7dc1649f4be9 ## Record-Breaking Polish Infrastructure A massive viaduct is currently under construction between Żarnowa and Godowa as part of the S19 expressway. Standing with pillars reaching 80 meters in height, the structure is set to become the tallest of its kind in Poland. This project represents a critical segment of the international Via Carpatia transport corridor. ## Scale of Engineering Materials The construction requires immense resources, utilizing 51,800 cubic meters of concrete for the supports alone, equivalent to over 20 Olympic-sized swimming pools. Furthermore, 9,250 tons of steel were consumed for the pillars, a weight exceeding the steel skeleton of the Eiffel Tower. These figures highlight the project's extraordinary physical scale and complexity. ## Advanced Cantilever Construction Method Engineers are employing the cantilever method due to the challenging, hilly terrain that prevents traditional ground-based scaffolding. This technique involves building the structure symmetrically from both sides of the pillars, extending over the valley. Specialized forming equipment allows for the gradual pouring of concrete segments until the spans successfully meet in mid-air. ## Logistical Challenges and Solutions Transporting materials to such extreme heights required innovative logistical strategies, including a dedicated pipeline system for concrete delivery. Five tower cranes were installed to lift heavy steel components into place. The first phase alone required over two thousand concrete mixer trips, demonstrating the intense coordination needed to maintain progress on site. ## Structural Dimensions and Comparisons The viaduct spans 1,082 meters in length and 29 meters in width, featuring a record-breaking 188-meter span. The scale is so vast that the taller tower of Krakow's St. Mary's Basilica could almost fit entirely beneath the highest support. These dimensions place the structure among the most significant bridge projects in Poland. ## Progress on S19 Expressway Construction on the Babica-Jawornik section began in late 2023 and is advancing rapidly. Bridge works are currently over 90 percent complete, while general road works have reached 70 percent completion. The first completed viaduct will now serve as a transport route to facilitate the construction of the second parallel structure. ## Revised Completion Timeline While initial projections suggested an earlier opening, the current expected completion date for the viaduct is October 2027. This delay reflects the technical difficulties inherent in such a massive engineering undertaking. Once finished, the facility will provide a vital link in the regional road network, significantly improving transit efficiency for heavy vehicles. ## Strategic Regional Impact The new expressway will fundamentally transform traffic patterns in the Podkarpacie region by diverting transit traffic away from local towns like Strzyżów and Czudec. Internationally, it completes a crucial link in the Via Carpatia route, connecting Baltic nations through Poland to Slovakia, Hungary, Romania, and ultimately Greece for improved logistics. ## Sources covering this story - https://wydarzenia.interia.pl/podkarpackie/news-stalowy-gigant-bije-rekordy-najwyzsza-estakada-w-polsce-rosn,nId,23567536 — --- _Summary written by Brifing from the original reporting.
