This article discusses the specifics of the construction of bridge structures in cramped conditions of dense urban development. The classification of bridge structures and features of each type are given. The main characteristics and weight and size parameters of elements of bridge structures, methods of their erection, transportation and installation are considered. Particular attention is paid to the arrangement of the construction site, transportation of finished products and materials to the construc-tion site, as well as measures to prevent damage to buildings, structures and transport routes adjacent to the construction site, including the railway.
The study considered the project for the implementation of the construction of the Strela overpass in the city of Tyumen. Emphasis was placed on the production of radial prestressed reinforced con-crete beams of span structures in construction conditions. It was decided to manufacture these struc-tures at the work site.
