PROBLEM $1$

A $+1\mathrm{.}7$ percent grade intersects a $-4\mathrm{.}3$ percent grade at station $150+60$ at an elevation of

$657\mathrm{.}88.$ Calculate the centerline elevation for every even $100-$ft station for a $400-ft$

vertical curve $(L=400ft.$

Hint: $$

You need to start the calculation of elevation at the BVC station and continue to calculate

the elevation every $100$ ft thereafter until you reach the EVC station. Organize these

calculations in a table. Show a sample of details of how you did the calculations.
