I think I misunderstood you, I should have read more closely. I go this way to work.
The bike path is technically closed past the Journal Center turn off bridge, however, you can usually go straight through, cross the Paseo frontage rd and turn left. The path is completed now, but there is construction sometimes. BTW, you will be going around the "Path Closed" signs this way. You know, be smart and go slow, but I go this way daily as do probably a hundred other bikers.
The official route is to turn off through the neighborhood on the west side of the path BEFORE you hit the Journal Center bridge. There's no good way to expalin this, you'll just have to watch for a fairly sharp downhill southward slope off to the side, head south half a click, then wind your way west and northward. Don't know the street,s but looking at the map I'd guess you come off the path at Willow creek then wind your way to Lomalitas. You'll have to cross the Paseo frontage Rd. here too, or jsut head down until you hit the Edith light, then jump on the path whcih will be on the right side of the street.
BTW, when I say frontage Rd. we're not talking anything like the interstates.
