The satellite image definitely shows that Michigan's most unique concrete t-beam bridge is no more. Check Bing Maps image for a photo showing the site after demolition was completed. What a waste... this should have been preserved for pedestrian use.

I can't find a report to confirm that this has in fact been demolished - the closest to that appears to be that the latest satellite seems to show that it's in the process of being demolished, but isn't completely gone as yet.
