This info comes from Commuter Challenge Ambassador Shari Gordon over at Washtenaw Friend of the Court:

I will be taking the following route on Friday, 5/15 for Bike to Work Day:

The starting point is at the Meijer on Ann Arbor/Saline. I will leave there at 7:30. If anyone wants to come along – it is a nice route because there is a safe crossing over 94 which was my biggest challenge.
