Freeway bridge in Mszana, Highway bridge in Mszana, Poland

The freeway bridge in Mszana is a 402.5 m long extradosed bridge over the Kolejówka valley, carrying the A1 motorway. Its deck is a two-cell prestressed concrete box girder with spans of 60, 130, 130 and 60 m, supported by three concrete-steel pylons rising 15.1 m above the deck. The bridge is curved in plan with a radius of 1500 m and widens from 38.58 m to 47.45 m to include the MD 532.1 connector ramp.

Construction began on 16 October 2007, planned for completion in 2010, but design disputes and delays postponed opening to 23 May 2014. The contract with Alpine Bau was terminated in 2009 and again in 2013; INTERCOR finished the bridge. It completed the A1 section from Pyrzowice to the Czech border.

The bridge's pylons and stay cables are painted purple, a visible detail for drivers crossing it. It carries the A1, known as the Amber Highway (Autostrada Bursztynowa), on the 18.3 km Świerklany–Gorzyczki section. Just west of it, the DW 933 crosses the motorway on a yellow steel tied-arch bridge, 95 m long and 29 m wide, whose deck forms a parallelogram because it crosses at an angle.

The bridge is located near Wodzisław in Silesian Voivodeship and is easily accessible from the A1 motorway. Travelers passing through the region will naturally encounter this crossing point while moving along the main highway corridor.

The bridge carries two wind indicators for drivers, one at each approach, because it crosses a wide open valley. Its pylons and stay cables are painted purple, and despite its record width the structure is not lit at night.
