INTRODUCTION. HORIZONTAL and vertical alignments establish the general character of a rural highway, perhaps more than any other design consideration.

Horizontal and vertical alignments establish the general character of a rural highway, perhaps more than any other design consideration. The configuration of line and grade affects safe operating speeds, sight distances, and opportunities for passing and highway capacity. Decisions on alignment have a significant impact on construction costs.
