2. A proposed road centerline to be constructed is shown below. The horizontal curve has a radius of 485.00', starts 1114.23' from the beginning of the new alignment (PCSTA=11+14.23), and ends 1500.34' from the beginning of the new alignment. Calculate the curve data (L, I, T, N Woter Tower 24 from Edge of Trovel P.C. Sto 11+14.23 P.T. 3. Use the same alignment as in Problem 2. Does the Water Tower obstruct the westbound driver's sight distance from the PT to the PC? Assume 12 feet from the center line to edge of travel. (Thus it is 30' (i.e. 12'/2 + 24') from the centerline of the inside lane to the edge of the water tower.) 4. For this same curve, what would the acceptable posted speed / design speed (assume to be the same) be to ensure stopping sight distance.
