The paper is devoted to elaboration of technique of a complex investigation of an extensive and massive long-standing viaduct at passing the peak of the exploitation term of 80 years under the urgent condition and small accessibility. The seismometry profiling resulted from not only integral assessment but data on weak points for the further detailed, local examination by ultrasound and sclerometry which gives materials for checking calculation. Seismotomography is predesignated for massive structural elements and resulted in the pattern of isolines of equal speeds of longitudinal sound waves. This allows to gain the mean actual strength of concrete independently of the destroyed superficial layers. Analysis of the ratio of speeds of the transverse and longitudinal waves can be used for determination of the crack texture of concrete and presents the basis of elaboration of a new method.
