Question

A highway reconstruction project is being undertaken to reduce crash rates. The reconstruction involves a major realignment of the highway such that a 60mph design speed is attained. At one point on the highway, a 720-ft equal tangent crest vertical curve exists. Measurements show that 3 40 stations from the PVC, the vertical curve offset is 3.5ft. Assess the adequacy of this existing curve in light of the reconstruction design speed of 60mph and, if the existing curve is inadequate, compute a satisfactory curve length.

Answer 1

The provided length of the vertical curve is satisfactory for the reconstruction design speed of 60 mi/h
