History of the all-welded Evgeny Paton Bridge
Abstract
This article explores the history of science and technology through the lens of the design, fabrication, and long-term operational experience of the Evgeny Paton Bridge in Kyiv, the world’s first all-welded highway bridge. Completed in 1953 and named after prominent welding pioneer Academician Evgeny Paton, the bridge represented a milestone in civil engineering and Soviet technological ambition during the postwar reconstruction era. The study examines the scientific and technical foundations that enabled the transition from riveted to welded structures, highlighting advances in metallurgy, structural analysis, and welding technology developed. It also considers the bridge's fabrication process, which involved large-scale application of automatic submerged arc welding and innovative solutions to challenges related to joint integrity, fatigue resistance, and thermal stresses. Drawing on archival materials, technical publications, and historical records, the article situates the bridge within broader political, institutional, and economic contexts, analyzing its role as both a functional infrastructure project and a symbol of Soviet scientific progress. The operational history of the bridge over more than seven decades is reviewed, emphasizing its structural resilience, maintenance practices, and the lessons learned that influenced later bridge engineering within the USSR and globally. It reflects on the interplay between scientific experimentation and practical engineering solutions, demonstrating how theoretical research was actively tested and validated through real-world implementation. The bridge’s continued use into the 21st century provides a living laboratory for studying the long-term behavior of welded steel structures under dynamic loading and environmental stressors. In doing so, the article underscores the enduring relevance of historical technological achievements for current infrastructure policy, materials science, and engineering education. The Paton Bridge thus serves as a compelling case study in the evolution of large-scale welded construction and the ways in which technological innovation is embedded in broader historical narratives.
