Urban transportation expert Bob Kennedy, previously interviewed (June 15, 2018, "The Last Mile, Uber to Red"),  proposes elimination of the interstate through our central city.

"Interstate traffic," he says, "can go around."  Beautiful boulevards can change the downtown.  Air and other pollutants (such as rubber), can and should be reduced.  Tolling is a viable option.  Interstate traffic could run below ground level.  These all are stimulating ideas in this conversation.
