Today infrastructure cannot be imagined without roads and bridges. In the world, special attention is paid to their condition, which in turn is an extremely important factor in ensuring the safety of the civilian population and the entire infrastructure in general. One of the main reasons for the deterioration of the condition of bridges is that a huge number of them have stepped over the 50-year mark and no longer meet technical standards. The article presents the reasons for the weakening of the load-bearing structures of bridges, as well as the influence of groundwater or river water on these structures, which together can lead to multimillion-dollar costs or, even worse, to tragic consequences. Calculation methods were given to determine the settlements of structures, such as absolute or total settlement, average settlement, heel and horizontal displacement. Methods for organizing remote monitoring of the state of the position of the bearing structures of bridges are considered. One of the considered solutions is a bridge condition monitoring system using satellite systems, which can consist of several segments, such as the ground segment, consisting mainly of measurement sensors, the space segment responsible for the centralized collection of information from all sensors, and the ground segment responsible for processing the information received and alerting the relevant departments in case of emergency. Wireless sensor networks are considered as the second method of organizing monitoring, since today they are most used in various industries and have the prospect of further improvement.
