This would really be a question to ask someone you know or look at statistics. Personally, I would guess you would be working near or at Monsanto (Olive St. Rd. & Lindbergh), because that's where I see the two routes cross. The area around there is a great area with homes, appartments & condos in about every price range, so you might want to consider there. Also, great school districts. Ladue, Pattonville & Parkway are all right there.
Here are the links for the route maps if anyone else has any ideas.
