Description

Diverging diamond roads have been used in France since the 1970s, but the use of the pattern exploded in recent decades. The diverging diamond interchange was listed by Popular Science magazine as one of the best innovations in 2009 in the engineering category.

The design also falls in line with the Federal Highway Administration’s Every Day Counts initiative. It’s a program that encourages the use of technologies and methods that improves travel time, safety, project and contract management, saving energy, risks, cost, and environmental resources.
