A new interstate quality highway connecting Illinois and Indiana has been planned for over forty years. It has become controversial. Some people think we should devote all of our resources for transit and redevelopment of older areas.
But the Chicago region and the nation as a whole continues to grow. Much of this growth is auto dependent. Wishing that everyone would take transit is wishful thinking and impossible for much of built environment.
The map below illustrates the need for the Illiana. Lake Michigan funnels traffic demand to the south end of the lake. The convergence of roads shows the need.
The Illiana will keep traffic out of the crowded Chicago expressway system. This reduce congestion, oil consumption, frustration, and air pollution. The Illiana should be built.
