Given:

A four$-$lane rural divided collector road $($u$0=70$ mph$)$ on a rolling terrain, ADT over $6000$ vpd$,$ high$-$type pavement.

Using maximum values and assuming:

$-$ Centerline construction to be the middle of the road,

$-$ Positive longitudinal grade to be equal to $+3\%$ and the negative longitudinal grade to be equal to $-6\%,$

$-$ The road is normal crown, and

$-$ The length of the vertical curve to be equal to the minimum length.

$3)$ Provide a cross$-$sectional view of the road at station $3000+00$ and attainment of superelevation.
