25. For a preliminary vertical alignment of a roadway, the straight tangent sections are established as follows: Station 0+00, tangent elevation = 1055.00 Station 23 +00, tangent elevation = 1107.75 Station 40+00, tangent elevation = 1056.75 Station 65+00, tangent elevation = 1156.00 Determine the gradient of each tangent and the eleva- tion at 1000-ft intervals along the tangents.
