Bridge across the Ostravice River

Completed in 2007

The motorway viaduct of a total length of 306 m consists of two parallel bridges which cross the Ostravice River and local roads at a very skew angle of 33°. Bridges of four spans are made up of longitudinally prestressed single‑cell box girders, which are supported by one bearing on the internal supports; in torsion, the girders are fixed at the end abutments. The composite girders of a variable depth from 2.70 to 5.00 m are assembled from steel beams of a trough cross-section and from a transversely prestressed concrete slab. The steel structure was erected in a progressive cantilever running from one abutment to another. Static effects in the erected cantilever were reduced by temporary supports.
