There are about a zillion different ways you could make that trip. Here's one option that I'd try because it's a pleasant route that is on boulevards and lots of pretty streets with very few cars. http://www.gmap-pedometer.com/?r=682857
You could also stop by the Portland Building on your way and pick up some free bike maps. Just come to the 8th floor and you should be able to get what you need for free.
Enjoy the ride.
