Bridge over the Mže River

The stone arched bridge has three fields. In the 1980s, the existing supporting structure was "lightened" with a new embedded reinforced-concrete continuous slab structure. This new part of the supporting structure has a span of 3 x 26.65 m. In the central part of each panel field, it is lightened by a transition to a beam cross-section (4 beams in total). The structure thickness in the central part is 0.80 m and it is reinforced to 1.14 m above the supports. The inner supports are built on the original stone piers and the outermost supports are set on the edges of the outer arches.
