Bridge across Porubka Creek

Completed in 2018

The twin bridge is formed by a continuous girder of eight spans. The deck of each bridge is formed by a box girder that is assembled of a steel girder of the trough cross section and a composite cast-in-place concrete slab. The steel girders were incrementally launched; the deck slab was incrementally cast in a formwork suspended on movable scaffolding.
