As a resident of Delta Township, I agree with your assessment of Saginaw. Our stretch is always busier than what I see down town. But I'll acknowledge that I'm not usually downtown during rush hours.
The reason it needs to be four lanes is because during both rush hours, and virtually any time during a weekday, all the traffic coming from the East and West travels through the one way stretches. That means A LOT of traffic, like I said I thik the bes way to handle that corridor is to imitate the divided section of MLK.
LMich, I provided NorthWest Initiative with the LSJ story, which I got from the local history librarian at CADL. While not the complete article, I've placed what I have on flickr at: http://www.flickr.com/photos/25425377@N07/2396580882/
