At km 1+271, the county road DJ707 crosses the Mureș River near the locality of Săvârșin. The bridge has four spans, each 39.80 m long, with a total length of 175.00 m. The bridge was built in 1897 and reinforced in 2007, with the works focusing mainly on the superstructure. The superstructure of the bridge consists of four metal decks, each with two main girders with parabolic-shaped crossbeams. The superstructure is supported on the substructure by metal bearing devices. The substructure of the bridge (piers and abutments) is made of masonry with dressed stone blocks, bonded with cement mortar. The carriageway on the bridge is 4.20 m wide and has two sidewalks, each 0.90 m wide. Currently, visual inspections reveal that the main girders, as well as the metal stringers and crossbeams and the reinforced concrete slab of the deck, show signs of degradation such as: corrosion, rust spots, flaking of paint layers, local deformations of parts due to corrosion, significant reduction of the cross-section of metal elements due to corrosion, and unevenness of structural elements. The substructure of the bridge shows defects and degradation such as: degradation of the protective jackets of the foundation blocks and significant degradation in masonry, with displacement of blocks at the pier foundations, lowering of the bed with exposure and erosion of foundations, insufficient embedding, cracks and fissures in the retaining walls, masonry with a crumbling appearance, friable and flaking masonry, masonry joints washed away by infiltration, infiltration and efflorescence, presence of vegetation on substructure elements. Exposure and erosion of pier foundations are also noted. The bridge ramps have the carriageway made of asphalt pavement, ensuring a width of approximately 5.50 m. The asphalt surface shows cracks, fissures, potholes, is aged and porous. Furthermore, the carriageway on the bridge is made of asphalt concrete, has a width of 4.20 m and does not correspond to a bridge located on a county road classified as technical class IV. It shows cracks, fissures, potholes, raveling, rippling, and potholes. According to the technical expertise carried out in 2023 by SC PROCONSINFRA SRL, the bridge is in an unsatisfactory technical condition. According to the recommendations of this technical expertise, a tonnage restriction of a maximum of 7.50 tonnes is currently in place.
