Go East on West Rd towards Grosse Ile. Turn right (South) on Allen Rd. Left (East) on Van Horn Rd. Turn Left (North) at Jefferson Ave., make an immediate right at the light and go across the free bridge to get onto the island. When you get across the bridge, turn right on Meridian Rd. Go about 1 mile until you see the sign at the road for THE LAB on the right hand side. (If you get to GROH street, you've gone 1 block too far.)
