2.1.2 Bridge across the River Váh's Reservoir Hričov,
section Žilina-Strážov - Brodno, Slovakia
2.1 MSS M45-S, Slovak Republic
The MSS M45-S was developed for the construction of
a motorway viaduct between Sokolov and Tisová and
for a bridge across Opatovický Kanál, both in the
Czech Republic, and again later for the construction of
viaducts between Poprad and Prešov in the Slovak
Republic. In 2017 it was also used for a motorway
viaduct on the D3 highway between Strážov and
Brodno in the Slovak Republic.
The bridge is part of the D3 motorway project near
the city of Žilina. The twin bridge with a total length
of 1.5km is formed by a continuous structure of
span lengths from 30.5 to 110m. The left viaduct
has 9 spans of 44m. The right viaduct has 8 spans of
44m, 1 span of 38.3m and 1 span of 27m.
2.1.1 Description of the MSS
It is an overhead MSS with an organic prestressing
system (OPS) for spans of max. 45m and max. deck
width of 14m. It comprises a steel truss with a top
arch. Typical performance cycle is 10 days.
Formwork for this project was modified in
cooperation with its supplier due to the proximity of
the decks and the radius of curvature on plan (low
and variable).
The construction period was 48 weeks. The MSS
allowed the client its reuse.
