abstract={Seeking the origins of the reinforced concrete (RC) technology, one certainly meets the name of  Fran?ois Hennebique. His genius and powerful organisation, known as <i>Le B¨¦ton Arm¨¦ Syst¨¦me Hennebique</i>, were crusial for developing RC in theory and practice. And it is bridges that played a significant role in his activity. Nowadays, the city of Lublin, Poland, may pride itself on two bridges in Hennebique technology, the heritage of those great days. The following is a concise account of the successful restoration of one of the two bridges but also a presentation of the other one being in great need of renovation. The bridges mentioned above were constructed by the Polish engineer Marian Lutos?awski, who highly deserves being treated as a RC pioneer. The structure of Lublin¡¯s bridges was thoroughly examined in many aspects, especially by applying a FEM analysis, non-destructive methods and a testing compressive strength on the cores taken. The carrying load capacity was estimated in accordance with the Polish standards and Eurocodes. As a result of the restoration there appeared a possibility of formulating a thesis on the concept of the RC beam Hennebique bridges as a modified form of  beam wooden ones. The arguments which definitely prove the thesis have been formulated. Both of the bridges mentioned above constitute a significant contribution to the world's RC technical heritage.},
