Summary: subgrade conditions should be avoided. (iii) The alignment should be such that it should not have any sharp horizontal curves or sharp vertical crests or hollows which cause danger to traffic. (iv) The alignment should pass through as many villages as possible so that the maximum number of people can derive benefit from the road. (v) The alignment should also avoid cutting across gardens, orchards, and fields so that the disturbance to the agricultural land is minimized. (vi) The alignment should be worked out in such a way that the maximum length of the road should run along the contours and the high banks and deep cuttings should be avoided. These are some of the general considerations to be kept in mind while selecting the alignment for a road project. It is essential to balance the engineering, environmental, social, and economic factors when determining the best alignment for a road project.
