Heroin & Tolls

As the talk about building a new bridge between Covington & Cincinnati that would require tolls for financing goes on (&on&on&on) there's another discussion about heroin abuse, an epidemic that has people crossing state lines over the existing bridgs.
What would tolling the bridges, existing & new due to the cross state heroin trade?
Tolls for the imagined bridge would all need to go to that bridge but tolls on the other bridges could go to not only the new bridge & existing bridge maintenance but some could go to chemical dependency programs as well.
Of course, getting stuck in traffic on the bridges would also afford a guy a great opportunity to shoot up…
