Describe what design speed was used for the curve

Reference no: EM13305662

A horizontal curve was designed for a four-lane highway for adequate SSD. Lane widths are 12ft and the superelevation is .006 and was set assuming maximum fs. If the necessary sight distance required 52ft of lateral clearance from the roadway center line, what design speed was used for the curve?
