He undergo risk and to fight for his work, to stand up for ideas and to establish a justice. However, he was combined successfully the pedagogical and scientific work with designing and supervision of bridges construction. He made a great contribution to the crea- tion of fundamentals of designing the span structures of bridges, the technology of their construction and test methods. According to the projects of Paton E.O., more than 40 bridges of unique designs were constructed, among which is the Mukhransky bridge across the Kura river in Tbilisi, bridges in Kiev across the Dnieper river and Petrovskaya alley, over- and under- passes in Moscow, roofing structures of halls of Kiev Polytechnic Institute and hotel «Metropol». At the beginning of the World War I, Paton E.O. developed the design of split bridges, won a victory over J. Eiffel, the French engineer, at the international competition. In 1929, E.O. Paton was elected the academician Mukhransky bridge across the Kura river, connecting two of the All-Ukrainian Academy of Sciences (AUAS, regions of Tbilisi in 1911. Evgeny Paton designed the bridge now NAS of Ukraine) and that year became as a with arch single-span structure instead of ordered three-span structure new stage in his creative activity. 2 3-4/2015 In 1927, the bridge after Eugenia Bosh joined Kiev with worker’s settlements and all the left-bank part of Ukraine. E.O. Paton had to solve the unique problems, such as to repeat contours of Nikolaevsky chain bridge, bombed during the war, which was liked by the kievites, and «to tie» the In 1909, E.O. Paton, participating in the competition, sug- beams of its dismountable bridges of the war-period to the gested to make alley in the Tsarsky garden and to construct retained supports of the chain bridge the arch bridge. In accordance with his project the bridge was constructed on land and with readiness the ground was Paton E.O. inspired the idea to apply welding dug, structure was lowered and mounted on the prepared instead of riveting in construction of bridges.
