Determine the minimum necessary clearance height of overpass

Reference no: EM13309955

An overpass is being built over the PVI of an existing equal-tangent sag curve. The sag curve has a 70 mph design speed and G1 = -6% G2=+3%. Determine the minimum necessary clearance height of the overpass and the resultant elevation of the bottom of the overpass over the PVI.
