Ladder over the river Lubina in Příbor

… a bridge like a stone laid across water
... a lapidary bridge
… a statue bridge – the statue of the bridge
… a bridge made of noble materials

The bridge is designed as a minimalist object made from perfect material. The most essential aspect is the sculptural quality of the bridge. The simple geometric form and the removal of everything insignificant allow the visitor to intensely perceive the basic content of this archetype. The form of the bridge is lapidary; a bridge like a stone laid across water is the oldest form of bridges. The surface of the bridge is noble, and the structure is designed from polished smooth concrete. The railing is made of circular stainless steel rods, while the handrail is wooden, massive, wide, and coated with marine varnish. The lighting of the bridge is provided by lights in the handrail of the railing.

The footbridge over the Lubina River in Příbor is a unique segmented structure, the first of its kind in the Czech Republic. The footbridge is designed as a simple beam with a span of 35 meters, created by the connection of 5 two-chamber segments, each 7.2 m long, 2.5 m wide, and 0.8 m high. From a static perspective, the load-bearing structure has a unique slenderness ratio of height to length of 1:44.
The construction material used is UHPFRC class C110/130 with dispersed steel reinforcement, which was developed at the Klokner Institute of the Czech Technical University in Prague. UHPFRC (ultra-high performance fiber reinforced concrete) is a new high-value cement composite material. Its mechanical properties (compressive strength of 120-180 MPa, tensile strength in bending of about 20-40 MPa) and processability allow the design of new structures with specific parameters and shapes. At the same time, the extremely high durability, which far exceeds that of ordinary concrete, is crucial for its use. Due to its exceptional durability and resistance, the surface of the structure can be walkable directly without additional waterproofing and covering surfaces. The volume of the footbridge is lightened by twenty large polystyrene blocks. Thus, it constitutes a hidden grid structure consisting of a system of mutually interacting longitudinal and transverse ribs.

The segments of the footbridge are longitudinally connected by prestressing cables guided in the longitudinal ribs of the internal grid. The prestressing is, unusually for segmented structures, solved by raised cables in a parabolic arrangement. A unique multiple protection system for the prestressing cables is designed for the footbridge.
