In the Kriváň-Mýtná section, the R2 expressway runs on two viaducts with lengths of 4,360 and 1,630 km. The first viaduct transfers both directions of the expressway on the structure, which has a similar arrangement along its entire length. It consists of a box girder with large overhangs supported by prefabricated struts. All internal supports are formed by pairs of slender walls. The central part of the 2,080 km long viaduct is formed by cast-in-place cantilever bridges with spans of length from 70 to 150 m. The depth of the box girders is from 3.50 to 9.00 m.
