Fit-up issues between girders and cross-frames are not uncommon due to deflections and rotations of curved girders (determining camber is more demanding than in straight girders)

Cross slope: Normal cross slopes: it is an important element used to prevent water from staying on thepavement surface and then penetrate through pavement materials causing pavement failure. The

Curved structural concrete bridges have a box shape, which makes the torsional stiffness very high and thus reduces the effect of curvature on the structural design. The objective of this chapter is to
