    3. (Optional) Input a Horizontal Offset distance to graphically position the Approach Reference line left (-ve) or right(+ve) of the alignment intersection.
    4. Type Offset from Support Line, i.e. the distance between the nearest support line and the approach reference line, measured along the alignment.
    5. Select the appropriate Location at Start or End of the Bridge.
