The paper presents two new technologies for the construction of single-span road bridges using the DMS-65 folding bridge structure. These technologies have been successfully applied in practice and resulted in savings in bridge construction time and cost. The presented technological solutions allow to organize the construction of small bridges in conditions of limited space for the construction yard.

The article presents examples of the use of portable bridge structures in civil engineering. Due to the possibility of combining elements of these structures into a variety of complex spatial arrangements, they could be widely used. Various technologies and principles of organisation of the construction of engineering structures of pre-fabricated bridges are presented. The presented solutions are both technologies known and used since the beginning of the history of panel bridges, as well as new technologies, developed on the basis of practical experience of engineers. The article presents selected scientific principles of work organisation, influencing the maintenance of a high rate of implementation of the construction project. The article also analyses the influence of location conditions, different from typical standard assembly stations, on the technology and organization of construction.
