The project will begin at station $62+00\mathrm{.}00$ at a tangent elevation of ${158\mathrm{.}29}^{\text{'}}$ The project will commence down a grade of $-6\mathrm{.}250\%.$ Along the project at station $62+60\mathrm{.}00$ there will be a PVC for a symmetrical curve $200\mathrm{.}00\text{'}$ long. At station $63+60\mathrm{.}00$ the grade changes to a grade of $+2\mathrm{.}650\%$ of grade.

At station $64+71\mathrm{.}28$ a PC for a horizontal curve is located. At station $65+25\mathrm{.}00$ a second symmetrical curve begins at that PVC$.$ At the PVI Station of $66+00\mathrm{.}00$ the grade will change to $+5\mathrm{.}300\%$ of grade. The project will end at station $67+00\mathrm{.}00.$

The horizontal curve will have the following data:

$=30{00}^{\text{'}}{00}^{\text{'}\text{'}}$

Centerline $R={253\mathrm{.}00}^{\text{'}}$

Project Width $-{37\mathrm{.}00}^{\text{'}}$

Offsets $={4\mathrm{.}00}^{\text{'}}$

Problems:

Compete the finish elevations for the project to include all stations for the project on the Grade Computation page.

On a sheet of engineering paper draw a profile of the project at the following scales:

Horizontal Scale: $1^{\text{'}\text{'}}={50\mathrm{.}00}^{\text{'}}$

Vertical Scale: $1^{\text{'}\text{'}}={5\mathrm{.}00}^{\text{'}}$

$3.$ Complete the horizontal curve calculations for the project on the Horizontal Curve page.
