Compound Curves: For open highways, compound curves between connecting tangents should be used only where existing topographic controls make a single simple curve impractical. When compound curves are used, the radius of the flatter curve should not exceed the radius of the sharper curve by more than a ratio of 1.5:1 (see Figure 4-02).
