marquette interchange, anyone?
If the 1 Billion $ rebuild of the Marquette interchange in downtown Milwaukee was a such a good idea, then someone in the private sector would have funded it. In fact, every interstate in Milwaukee, yea even Wisconsin, is free - not a single toll transponder or booth to be found!
When the private sector is building your roads and interchanges, then we can talk about private industry building other transport like trams, buses, and trains.
As long as the public thinks that transportation is worthy of government funding via roads & interstates, then it should think that ALL transport is worthy of government funding, and that includes sidewalks, bike lanes, transit bus & tram services, Amtrak, Metra or the proposed KRM, and everything else that helps people travel and provide economic benefits to their communities.
