IF you have visibility (i.e., have a rear blinkie and/or high visibility vest with you), do it as a vehicular cyclist. Travel in left tire track of the right lane (not sure if you mean two lanes each direction, or two lanes total, but it really doesn't matter). You'll be amazed at show much respect you get from cars when you are squarely in their lane. DO NOT ride along the right side of the lane; it is an invitation to pass, and if there isn't enough room for all vehicles to pass safely, you're putting yourself in danger. Just take the lane and be done with it.

It wasn't so long ago that I would have tried it as a gutter bunny or maybe taken the sidewalk, but taking the lane really is the best, safest solution.
