This paper presents a new type of emergency bridge, called Mobile Bridge, which can be quickly constructed in case of damage after a natural disaster. The concept of the bridge is based on the application of a scissors mechanism, which enables its rapid deployment. In the case of deployable structures as well as the static analysis of different configurations of expansion, it is important to investigate the dynamic behavior of the system. The high compliance and flexibility of the scissors-type bridge may influence the comfort and safety of users in case of heavy dynamic loads such as human-induced impacts, wind gusts, or earthquakes. Up to now, the authors have constructed several types of the experimental Mobile Bridges. The presented research reviews fundamental numerical and experimental results for the Mobile Bridge 4.0. Experimental testing included strain and acceleration measurements in free and forced loading conditions. From these results, it was possible to estimate basic mechanical characteristics, including the static and dynamic properties, of the bridge. The conducted research allows for better and safer design of the structure of the Mobile Bridge.
