SPECIFICATIONS DEFINITIONS A driveway approach or access is understood to be that portion of the highway right-of-way between the pavement edge and the property fine which is designed and used for the interchange of traffic between the roadway and the abutting property. INTERSECTION CLEARANCE At any intersection, a driveway shall be restricted for a sufficient distance from the intersection to preserve the normal and safe movement of traffic. Ilt is recommended for rural residence entrances that a minimum intersection clearance of 50 feet be provide) and for rural commercial entrances a minimum of 100 feet be provided.) SIGHT DISTANCE - All entrances and exits shall be so located and constructed that vehicles approaching or using them will be able to obtain adequate sight distance in both directions along the highway in order to maneuver safely and without interfering with highway traffic. Stopping sight distance is that distance required for a vehicle traveling on a horizontal curve to stop before reaching an object in it: path. Stopping distance is measured from driver's eyes, which are 3.5 feet above road surface of the inside lane and the object is f inches high. The fine of sight is assumed to intercept the obstruction at the midpoint of the light line and 2.0 feet above road surface The following chart may be used for reference: Design Speed MPH 30 35 40 45 50 55 Minimum Stopping 300 300 300• 375• 450' ~ 575• Sight Distance (feet) The stopping sight distance of any roadway design should never be less than the minimum for the design speed. - `Based on road conditions and traffic count, stopping sight distance requirements may vary from the above given distances. CONTROL DEVICES ~ ~ .~ The Applicant shall not be permitted to erect any sign or display material, either fixed or movable, on or extending over any portion o~ the highway right-of-way.

The dimensions of all drainage structures will generally be based on Talbot's Formula and muss be approved by the Department representative prior to installation. The minimum size on culverts is t8 inches by-20 feet unless special permission is granted.
