Proposed streets shall intersect one another as nearly at right angles as topography or other limiting factors will permit. No intersection of streets at angles less than sixty (60) degrees shall be approved unless justified by extreme topographical conditions. In such a case, special provisions as deemed necessary by the Commission shall be made in designing the intersection to afford a satisfactory sight distance of approaching vehicles from each intersecting street.
Residential street intersections shall be rounded with a twenty-five (25) foot radius measured at the back of curbs, if such intersections occur at right angles. Under the same condition and measured similarly, all other intersections shall be rounded with a radius deemed appropriate by the Commission. If an intersection at an angle less than sixty (60) degrees is unavoidable, the radius of curvature shall be such as to allow vehicles, especially trucks and buses, to make right turns and proceed in the proper lane without encroaching upon the high speed lane of a multi-lane thoroughfare or across the centerline of a two-lane thoroughfare.
Streets jogs at intersections with centerline offsets shall be avoided. Points of access to a primary or secondary route shall be spaced at a minimum of 800 feet.
