Late last year I posted that two new sections of the Kinnickinnic River Trail had opened. Unfortunately the street from downtown Milwaukee to these sections was in terrible shape, with potholes and numerous old railroad crossings. South Water Street has now been repaved so the route is now more comfortable, particularly for those concerned about their tires. Thus this route is a viable option for part of the Milwaukee-Chicago route.
I am attaching a photo of the bridge carrying the new trail over Chase Ave, taken when it was under construction.
