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.
