Intersections of local streets with local or collector streets shall not be located less than 150 feet apart; intersections of collector streets with collector streets shall not be located less than 200 feet apart. Intersections of any street with arterial streets shall be located not less than 1,000 feet apart.
(c) Multiple intersections involving junctions of more than two (2) streets shall be avoided.
(d) Four-way intersections of local streets should be avoided where possible and three- way or T-intersections should be encouraged wherever possible.
