Arch bridge KASI is a pedestrian and bicycle underpass build with precast concrete foundations and steel arches, which makes efficient use of space. Concrete foundations are two or three meters long, ready-to-install elements. At the ends of the bridge, either straight or oblique wing walls can be installed. You can find information about other end solutions in our Holvisilta brochures.
The arch bridge has a prefabricated structure, which makes its installation quick and cost-effective. The arc part is made of hot-dip galvanized steel up to 4,6 meters in span. Larger spans are realized by the multi-plate structure. Arc parts can be equipped at the factory with LED lamps and painted in the desired color tone. The concrete part is also available with washing concrete, different color options or special patterns.
The KASI-BOX structure differs from the KASI structure only in the BOX shape of the steel arch. The equipment can be implemented in the same way as in KASI.
The BOX shape enables a shallow overall structure and provides the overall structure with a spacious solution that makes good use of the passage space, and the necessary opening requirement is achieved efficiently.
