“…Flexible steel structures, made from thin corrugated steel plates, constitute an efficient alternative to traditional bridges and culverts [11,12]. This solution has been in use since the 1960s [13] due to its reduced price and construction time [14]. Studies on deterioration mechanisms, service life estimation and rehabilitation approaches consolidated their application as efficient infrastructure solution and proved that a service life of 100 years could be reached through the application of adequate coating systems [15][16][17].…”

The objective of the project was the rehabilitation and expansion of one bridge, located on the DN28 (a national road) in Sarca, Iasi County. The solution includes an atypical use of the flexible galvanized steel structure. The main challenge in this case was to finish the works without any traffic interruption on this section of the national road, as well as the assembly of the said corrugated steel structure under the existing bridge. The work was executed in record time and with reduced costs in comparison with the classic alternative solutions, such as concrete bridges. The paper highlights practical aspects from the key moments of the project and presents the major challenges and how they were solved for both the design and the construction stages.
