This paper presents design, realization and testing process of 1-st UltraCor structure in Europe. The scope of the design and intalation is 25.50 m Span, 9.00 m Rise structural plate structure of 500x237mm corrugation with only 9.5 mm plate thickness. Structure will cary the heavy traffic of S7 express road. It was designed for the highest class of loads acc. to Polish Standard. Under the structure there is a local raod and animal crossing.

This paper presents how to solve the end treatment for buried steel structure designed initially in an incorrect way. Structure VR9 with span of 4.77m and rise of 3.83m was designed with skew of 28 degree with beveled end cut 1:1.5. Due to heavy loads LM1 LL vehicle the cut end would be subjected to huge deformations. The solution of the problem required the designing of: geogrids to reduce the horizontal active pressure and the 3D concrete frame to carry the vertical loads (soil and traffic). Fem 3D analysis and final solution of cut end reinforcement will be presented in this paper.

Paper presents an alternative solution to the classic issue - a flexible hurried steel structure as the superstructure of pedestrian underpass at Kapitulna street in Włocławek which provides crossing under the tracks of the electrified railway line Number 18 Kutno-Piła. Underpass was built in 2012 by HUSAR BUDOWNICTWO INŻYNIERYJNE commissioned by Włocławek city. The use of the corrugated steel structure allowed for a very quick execution of the investment, without detriment to aesthetics and functionality of underpass.
