Consider this route:
http://www.mapmyride.com/route/us/il...26435230131866
Take Oakton to the Channel bike path that runs along McCormick
Use either Howard or Touhy to cross over the canal, take Kedzie south
Pick up the bikepath just before reaching Lincoln
Take the bike path to Lawrence
Cross over the North Branch of the Chicago River at Lawrence
Head south on North Manor to California
Take California to Addison (you can ride through Horner park).
Take North Rockwell to Belmont, take Clybourn to Fullerton.
You could also improvise between Custer & Oakton and the intersection of Touhy & Kedzie, some neighborhood streets in Evanston might be better than the traffic on Oakton.
The mixture of bike paths and bike friendly roads will promote a low stress ride to work!
