§ 30-361. Roadway intersections.

(a)

Roadway intersections shall be designed to intersect as nearly as possible at right angles, except where terrain or other conditions justify variations. The minimum angle of any intersection shall be 60 degrees. All intersections of collector roads and roads of higher classifications shall be within ten degrees of a 90 degree angle. Property line and curb return radii at intersections with local roadways shall be less than 25 feet. When the angles of the roadway intersection is less than 75 degrees, the radius shall not be less than 30 feet. Property line and curb or return radii at intersections of collector and/or arterial roadways shall be per Table 5-1.

Table 5-1. PROPOSED INTERSECTION CURB/RETURN RADII

Functional Class	Area Type	Maximum Skew	Minimum Radius Return
Local/Local Local/Collector, or Local/Arterial Intersection	Rural Residential	30°	25 feet (30 feet if skew > 15°)
	Urban Residential	30°	25 feet (30 feet if skew > 15°)
	Commercial	15°	30 feet
Collector/Collector, Collector/Arterial, or Arterial/Arterial Intersection	Rural Residential	10°	35 feet
	Urban Residential	10°	35 feet
	Commercial	10°	45 feet

 

(b)

All roadway intersections, other than directly opposing roads or extensions of the same roads, shall be offset a minimum of 200 feet, as measured from the centerline.

(c)

Two-leg, "L" intersections shall be designed only for the intersection of two local interior roadways and shall be designed per Figure 5-1.
