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