e 72 is the martin luther king exit, go north and then west on n.marginal rd. edgewater is tricky . you have to get on from the shoreway and it only has entrances on e49 n of detroit rd. or west blvd. or you can hit the shoreway from 90 just b4 dead mans curve.
Straight out from Edgewater 3 or so miles, it's enormous you can see if from 72nd too on a semi clear day. If you put in at 72nd motor out past the lighthouse and look to your NW you will see it if you want to fish the crib I'd do edgewater it'll save you gas... Hettfield put a picture of it up a day or two ago, someone posted really good directions on how to get to edgewater as well.
