When I commute to work I go through a four-way stop light that crosses above a major freeway. In Minnesota bike riders ride in the same direction as the traffic. When I approach the stoplight the pedestrian signal is crossed out and you are supposed to go to the left, cross the intersection, and then go forward from there. This is a fairly busy intersection and I usually do have to stop. My question is do I stay with traffic flow and continue on or should I also go to the left and cross the intersection. It is strange because there are pedestrian sidewalks on the both side of the road -although I don't use them because they aren't good for riding. There must be a reason for the lights being that way but I sure can’t figure it out. There are no bike lanes on either side of the road.

I tried to draw it out here
