In accordance with the Russian Federal Target Program of Social and Economic Development of the Crimea and Sevastopol, a bridge across the Kerch Strait is being built now. Of course, such complex structures are significant for Russia. Solving technical issues at different stages of engineering investigations, design, construction and operation of such objects it is required to attract specialists from scientific, educational, design, construction organizations, and manufacturers of building materials, structures and equipment from different countries. Before the implementation of this project, more than 70 different variations of the construction of the transport crossing were considered. These are combinations of bridges (cable, arched, girder, combined, etc.), tunnels and embankments in four sections of the Kerch Strait. As a result of the multifactor analysis, the optimal variation of the transition through the Tuzla point of two parallel bridges of about 19 km in length, with beam spans of 55-64 m, arches with a width of 227 m and a height of 45 m in the navigable channel was adopted. The bridge clearance for passage of ships is 185 × 35 m. To design a unique and complex bridge under existing regulations, special technical conditions were developed. When piles were driven, there were difficulties and issues that required prompt solutions. Employees of the Department of Highways and Bridges of the Perm National Research Polytechnic University were involved in testing piles and hammers. The design of foundations and the technology of driving piles were changed as the test results were obtained.
