Existing equal tangent sag curve

Assignment Help Civil Engineering
Reference no: EM1383509

An overpass is being built over the PVI of an existing equal tangent sag curve. The sag curve has a 70 mi/h 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. (ignore the cross-sectional width of the overpass).
