Abstract


As part of the Reconstruction and Modernisation of Road I-8 Project in Bulgaria, demolition of an existing single-track steel railway overpass with a span of about 46.5 m and its replacement with a double track bridge designed in accordance with the Eurocodes is planned. As the road and railway traffic cannot be interrupted, it is necessary to temporarily shift the railway line and build a new temporary railway bridge, as well as to change the route of the I-8 in the construction site several times. The report presents information about the different stages of construction: construction and testing of the temporary bridge, removal of the existing steel bridge weighing about 180 tons and construction of the new bridge facility.
