The paper is presented the results of experimental research conducted on the new prestressed concrete road bridge over water plant on water reservoir across Nysa Kłodzka river in Topola under statical field load tests. The examined bridge was first time weighted so large loads and presumably followed fitting oneself of some structural elements to oneself, especially of parts of bearings, what appeared in the results of bearings and bridge spans under static field loads. On the base of the obtained results from research and calculation the behaviour of tested span structures was evaluated before putting it to the normal service, what it was permitted to evaluate an effectiveness of such solutions.
