Projektbeschreibung

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.

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.

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.

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.

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.

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.

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.

Beurteilung durch das Preisgericht

A good bridge is like a good deed in an unkind world, an altruistic investment in the public realm, a way to connect people and places, designed in such a way that it is pleasing to experience and to look at. Litomysl’s new footbridge is exactly that: an entirely convincing synthesis of architecture, engineering and urbanism, connecting two segments of the town, like a contemporary version of the Charles Bridge in Prague. In classical urban terms, it forms the decumanus to Smetanovo náměstí, the town’s cardo, or main square.

Litomysl’s bridge combines a concrete tower, which aligns with and echoes the baroque tower that defines the town centre, with a steel Vierendeel struc-ture. The two elements play off of each other like large-scale sculptural ob-jects.

The structural requirement to counterbalance the bridge’s main span results in a perfectly positioned look-out spot overhanging the bank of the Loučná River. A few carefully selected details have been added: a skylight in the ele-vator tower and calligraphic swirls by a local artist on the doors.

Neither boastful nor retiring, the bridge is exactly what is needed at this pre-cise location, and provokes neither questions nor vague second-guessing about intention. There is simply nothing more to it, which is a rare quality these days.

Still, the bridge has not been built in a vacuum. On the contrary, it is the result of the political and visionary continuity of this small city. In Litomyšl, the cur-rent and former mayors meet with the long-time city architect and brainstorm strategies for the city on a monthly basis. This is one of the reasons why Lito-myšl harbours such a rich collection of significant contemporary architecture.
