The article lists the first applications of the Joseph Monier patent for the construction of reinforced concrete bridges that took place on the Polish lands. The history of the construction of Monier reinforced concrete arch bridges by Biuro Techniczne Arnold Bronikowski & S-ka Inżynierowie in the Kingdom of Poland was described on the basis of written sources, iconography, literature and current records. In particular, these included the bridge on the pond in the Ujazdów Park in Warsaw, the Reformacki Bridge on the Rypinowski Canal in Kalisz, the bridge over the Czechówka River in Lublin and the viaduct along the Karowa Street in Warsaw. The basic technical parameters of these constructions, dates of implementation and current status were specified. The life and professional achievements of engineer Arnold Bronikowski were presented in the context of his constructions, both beautiful and innovative at the time. Three of the engineering objects described in the article survived the ravages of war and remain in use today.
