The longest and highest bridge in Finland

Designed to last for two centuries, it will be the exclusive path for public transport, bicycles and pedestrians. The TYL Kruunusillat consortium (YIT Oy & Kreate Oy) and the company TRB Rakennustoimisto Oy have entrusted ULMA to carry out this project.

The work on the pylon was carried out in two phases.
The initial V-shaped stretch was built using ENKOFORM HMK, a formwork capable of adapting to multiple geometries and supported on a T-60 shoring system. As the pylon increased in height, the formwork was adapted to the changing cross-sections up to a height of 31 m. During the second phase, the A-shape structure was carried out by combining the ATR and KSP self-climbing systems with HMK formwork and working platforms, which ensured efficiency and safety during construction.

Four ATR platforms have been installed on each of the pylon legs for the outer walls and KSP platforms on the inside. The systems have been designed taking into account the variable cross-section of the structure. The ATR assembly was modified before reaching the joint point to become a single structure up to the crown of the pylon.
