Appreciation towards Petr Tej + Marek Blank + Jan Mourek for providing the following description:

该项目是由优质材料制成的极简桥梁，其关键在于结构质量。简洁的几何形体以及去除无关紧要的部件，使来访者能够直观地感知桥本身。桥的形式十分简洁，如同铺在水面上的老式石桥。桥梁具有高品质的表面，其结构选用光洁的混凝土，栏杆由不锈钢条制成，扶手是木质的，坚固、宽阔且涂有清漆。

The bridge is designed as a minimalist object made of perfect material. The most important is the sculptural quality of the bridge. The simple geometric form and the removal of everything insignificant allows the visitor to intensely perceive the basic content of this archetype. The form of the bridge is lapidary, a bridge like a stone laid over water is the oldest form of bridges. The surface of the bridge is noble the structure is designed from shiny smooth concrete. The railing is made of round stainless steel bars, the handle is wooden, solid, wide, painted with ship varnish.

人行天桥位于摩拉维亚普日博尔的卢比纳河上，是捷克首例采用节段施工的桥梁。它被设计成跨度为35米的简支梁桥结构，由5个长7.2米、宽2.5米、高0.8米的双室节段闭合而成。从静态角度来看，该结构具有1：44的独特细长比。结构材料采用分布钢纤维的C110 / 130超高性能纤维筋水泥混凝土（UHPFRC），这种材料由位于布拉格的捷克技术大学Klokner研究所研发。UHPFRC是一种新型高性能水泥复合材料，它的力学性能（抗压强度120至180兆帕，抗弯拉强度约20至40兆帕）和施工性能使设计师可以设计特定参数和形状的新结构，其使用寿命也远超常规的混凝土结构。UHPFRC卓越的耐久性使该桥表面无需附加防水层和保护层即可通行。

The footbridge over the Lubina River in Příbor, Moravia, is a unique segmental construction, the first of its kind in the Czech Republic. The footbridge is designed as a simple beam with a span of 35 meters, which is created by the closure of 5 double-chamber segments of 7.2 m in length, 2.5 m in width and 0.8 m in height. From a static point of view, the structure has a unique slender ratio of 1:44. The structural material used was UHPFRC class C110 / 130 with dispersed steel fibers, which was developed at the Klokner Institute of the Czech Technical University in Prague. The ultra-high performance fiber reinforced concrete (UHPFRC) is a new high performance cement composite material. Its mechanical properties (compressive strength 120-180 MPa, bending tensile strength approx. 20-40 MPa) and workability allow us to design new constructions of specific parameters and shapes. At the same time, the service life far exceeds similar structures of conventional concrete. Thanks to its exceptional durability, the surface of the structure can be walked on without additional waterproofing and covering surfaces.

节段由排布在桥箱纵肋的预应力钢索固定，抛物线型钢索解决了分段结构的预应力问题。人行天桥上具有独特的预应力绳索保护系统。成对的200mm圆柱滚子轴承支座支撑了整个桥梁。

The segments are longitudinally clamped by prestressing cables guided in the longitudinal ribs of the inner grate. Prestressing is, unconventionally for segmented structures, solved by raised cables of parabolic course. A unique protection system of prestressing ropes is designed on the footbridge. The bridge is supported on supports by means of pairs of 200 mm cylindrical roller bearings.
