Echelon
Evolution of Design
The Echelon design was born of necessity for a
single intersection improvement project at US 1
and NE 203rd Street in Aventura, Florida. This design
location, opened in June 2000, is currently the
only known application in the world. The Echelon
Interchange was so named by the late Don Beccasio
of the Florida Department of TransportationB s Planning
Division, who worked on this initial design application.
The designB s feature of one intersection offset
and over another reminded him of the U.S. Navy Flight
Demonstration TeamB s "Echelon" formation, where each
plane flies offset and over one another.
