The Gostyń Bypass Bridge is a newly constructed bridge with a total length of 261 m (856 ft) and a width of nearly 12 m (39 ft). The bridge was built using the free cantilever construction method, implemented in cooperation with the strategic partner Strukturas AS.
BrandSafway supported the project with a comprehensive package of formwork, shoring and safety solutions, enabling safe and efficient construction of the bridge superstructure and substructure elements throughout all phases of the project.
The use of free cantilever technology required precise coordination between formwork, shoring and access systems, particularly during the construction of the cantilever segments and the final connection of the bridge halves. The solution had to provide high load-bearing capacity while ensuring flexibility for sequential concreting operations.
Additional challenges included the construction of hammerheads and the execution of the keystone connection, linking both sides of the bridge at the centre span. Throughout the project, maintaining a consistently safe working environment at height was essential, requiring integrated safety solutions across all working areas.
BrandSafway delivered an integrated solution combining formwork, shoring and safety systems tailored to the free cantilever construction process. MANTO® wall formwork panels were used for the construction of pillars, pillar foundations and abutments, providing robust performance and high-quality concrete finishes.
The ID-15new shoring towers were employed to erect the hammerheads, with free cantilever form travelers attached to support the segmental construction of the superstructure. For the critical keystone connection, an INFRA-KIT–based solution was implemented, suspended from the final cantilever segments that had been constructed using the form travelers.
To ensure safe working conditions throughout the project, the PROTECTO® edge protection system was installed, providing continuous and reliable fall protection across all construction stages. Together, these solutions enabled efficient execution, high safety standards and precise structural alignment.
