THE ECHELON INTERCHANGE
This paper presents a relatively unique concept for urban arterial highway interchanges. The interchange has been named the Echelon Interchange because of its symmetrical, but offset, pair of two-phase one-way pair intersections - one elevated over the other. It was noted that the interchange resembled a flying formation used by the U.S. Navy Flight Demonstration Team, the "Blue Angels," and called the "echelon" formation. The interchange is viewed as unique because there are no free-flow through-movements. Such an interchange would not be feasible for a freeway facility, where interchanges are most common. Because of the close association between freeways and interchanges, most interchange design concepts feature at least one pair of uninterrupted free-flow movements, and often, several pair of free-flow movements are featured.
