This road is similar to one I take on my way home during my "Big Boy" commute I make from home. In the afternoon the road is heavily traveled with a speed limit of 35 mph. However, drivers around here tend to drive 5-10 over. So, with that said, I would ride on the shoulder.
Now, there is a four lane road I take for both of my commutes (the other being a car/bike commute) that doesn't have a shoulder but does have a sidewalk. Again the speed limit is 35 w/everyone doing 5-10 over and it runs through a warehouse district so there are a lot of 18 wheelers. But for the most part traffic is light. On this road I ride as far right in the lane as possible. Never on the sidewalk. I don't trust sidewalks, because drivers don't pay attention to sidewalks and whats on them....IMO.
I never have a problem with the truckers as they always give me room and once in a blue moon someone will buzz me.
