带有电梯的全新人行桥取代了自1981年建成的原有天桥，为从市政办公室到市中心的人们提供了一条无障碍通道，并改善了穿越拥挤的I/35高速公路的路线。

The new footbridge with an elevator, which replaces the original overpass from 1981, provides barrier-free pedestrian access from the Municipal Office to the city center and enhances the route across the busy I/35 highway.

厚重的粗野混凝土支柱支撑着精致的钢结构。电梯塔位于原有楼梯的轴线上，朝向历史悠久的市中心，并支撑着人行桥结构。从广场穿过Ropkova街道，能够看到这座地标性高塔。

The subtle steel structure is supported by massive pillars made of exposed concrete. The elevator tower is located in the axis of the original staircase towards the historic center and supports the structure of the bridge. Tower creates a new landmark visible through Ropkova street from the square.

中央支柱延伸至新的混凝土楼梯，朝向通往斯梅塔努夫杜姆（Smetanův dům）的道路。从西边走近，能够看到桥梁支撑在原保留墙体的支座上。
The central pillar continues into a new concrete staircase oriented to the path to Smetanův dům. On the western approach, the bridge is supported on an abutment in the existing retaining wall.

金属焊接结构系统采用了双跨度连续梁结构，端头采用悬挑结构。这座桥的上层结构由两根Vierendeel主梁和其余横梁组成。
The structural system of the welded steel bridge structure is a continuous beam with two spans and cantilevered ends. The bridge’s superstructure consists of two main Vierendeel girders connected by transverse beams.

建筑师通过纵向叠加横向截面，塑造了带有正交面板和屋顶的三维空间Vierendeel主梁。钢筋混凝土体系由3.07 x 3.07 x 3.07 m的空间模数经过重复而形成。
By repeating of cross-section in the longitudinal direction a spatial 3D Vierendeel girder is formed with an orthotropic deck plate and the roof. The spatial module of 3.07 x 3.07 x 3.07 m is repeated in the reinforced concrete structures.

得益于采用HEB梁结构和横截面220 x 220 mm的焊合板，该人行桥实现了主梁边缘的精确度与整体几何造型。由于采用了该结构，人行桥能够抵抗恶劣的天气，还能让行人欣赏到树梢间卢奇纳河（Loučná river）的迷人景色。

The precision of the girder edges and the overall geometry was achieved by the use of HEB beams and welded plates in cross-section 220 x 220 mm. Thanks to the chosen structure, the footbridge provides protection against bad weather and offers an attractive view between the treetops over the Loučná river.

人行桥采用了不锈钢金属网和圆形扶手。灯光增强了轻质不锈钢结构和粗野混凝土之间的对比效果。Ivana Šrámková在电梯入口处和电梯塔后部墙壁上绘制的图案使简洁的建筑结构更加活泼生动。

The footbridge has railing of stainless-steel mesh and round handle. The lighting enhances the contrast between the lightweight steel structure and the exposed concrete. The simple character of the structure is enlivened by the graphics of Ivana Šrámková at the elevator entrances and the rear wall of the elevator tower.
