Locating points along or offset from a horizontal alignment is necessary to defining bridge geometry. This course presents a vector-based approach to locating the North and East coordinates of point defined by a horizontal alignment. The vector-based approach was taken as it closely follows the way CAD software is used. Vector solutions are presented for 1) Locating points on tangent runs and circular curves, 2) Locating points offset from tangent runs and circular curves, and 3) Project points onto a tangent run or circular curve.
