(a) Horizontal street curves shall have the following minimum radii of centerline curvature:
Street Type | Minimum Radii (feet) |
Arterial/main collector streets | 300 |
Residential streets | 100 |
(b) A minimum tangent of at least 100 feet shall be provided between reversed curves on all residential street; greater tangential lengths shall be required on collector and arterial streets and other high order thoroughfares.
(c) The Commission may modify the aforementioned minimum standards in the following situations:
(1) When a collector or residential street’s lines deflect from each other at any point by more than ten degrees, they shall be connected by a curve with a radius adequate to insure a sight distance of not less than 200 feet or with such greater radius as the Commission may deem necessary for the particular situation.
(2) For arterial streets, curves with radii adequate to insure longer sight distances may be required by the Commission.
