Bridges with Skew are very common at highway, river passage and other extreme grade changes, due to restrictions in space skewed geometry is necessary. Due to the needs for complex intersection and the troubles with space constraint in urban and metro city areas there is a growing demand for skewed RC girder bridges. There are many reasons such as when roadway alignment changes are not feasible or due to the topography of the site to maintain economic and as well at particular areas someplace environmental impact is an issue then the Skewed bridges are useful. A skew crossing may be essential if a road alignment crosses a river or other obstruction at an inclination different from 90�. The inclination of the centre line of Roadway to the centre line of river in case of a river bridge or other obstruction is called the skew angle. The analysis and design of a skew bridge are much more complicated than those for a Normal bridge. Bridges with large angle of skew can have a considerable effect on the behavior of the bridge especially in the various ranges of spans. A lot of research studies have been made to examine the performance of skewed highway bridges. However, there are no detailed guidelines addressing the performance of skewed highway bridges. There are many parameters which affect the response of skewed bridges which make their behavior intricate. Therefore, there is a need for additional research to work the effect of skew angle on the performance of RC girder bridges. As the Bridge plays a major part in Road Network since the Bridge Structure is affected by various parameters. The Skew angle is one of the major factor which is taken under consideration while Design and Analysis of Bridge. As the perpendicular crossing or right angle crossing of bridge is not possible due to site condition or due to the proposed alignment, the effect of skew angle of the bridge deck is finalized by modeling the bridge and the comparison of various skew angle effects. This will be done considering Bending Moment, Shear Force, Bending Stress, and Tensile Stress.
