Abstract
The field of repair and rehabilitation of civil engineering works is evolving. Indeed, most of these structures, especially masonry structures, are over 50 years old and many of them require maintenance and repair work due to their deteriorated condition. To achieve this objective, a study was carried out concerning the different pathologies affecting the masonry bridges, but also the ways and means necessary for the evaluation and repair of the affected works. The results of this work have not only helped to carry out the diagnosis and verification of the structural state of the bridge over river Kentra Stora Skikda (North-East of Algeria), on the section of the 3AA National Road Skikda, but also for the proposal of repair solutions best adapted to the disorders observed.

Summary
Masonry is a composite material, a mixture of stones or bricks and mortar joints. The behaviour of masonry structures depends on their physicochemical characteristics (porosity, capillarity, permeability, gelling), thermal and mechanical behaviour. Whose resistance to simple compression is lower than stone, of the order of 5 to 15 MPa. The overall mechanical operation of a masonry bridge is related to the individual functioning of each part (vault, walls, abutments) and to the connections and transmissions of forces between the zones. But given their social importance, they must be given special care so that they can perform their functions for the life they have been assigned (Modena, 2004) They are works, which, even if they do not all have an architectural aspect, constitute economic, transport and security vectors, built with the aim of ensuring a service combining high level of quality, safety and reliability. In this article we present the various pathologies affecting the masonry bridge on river Kentra Stora Skikda (North-East of Algeria), the ways and means necessary for evaluation and repair and the repair solutions best suited to disorders observed
