The paper presents the systematization of the main methods for increasing the rigidity and stability of the cable-stayed and hanging types bridge structures , its given in conjunction with the analysis of the real objects. Among the methods presented are such techniques as: improving the quality of the material; additional structural elements that perceive vibrations; modification of the main elements of the design scheme. Also in the paper innovative developments applicable in the field of study are described.
