Although hard-core vehicular cyclists will disagree with me, my behaviour in your situation would depend on traffic flow, visibility, road and weather conditions (e.g. rising or setting sun in one's eyes), etc. If the road configuration would indeed require me to hold up fast traffic in the inside through lane, i.e., there is no left-turn-only, center turns lane, or center divider in which I can take refuge, I will generally avoid this dangerous scenario by crossing at the preceding intersection and riding the sidewalk on the wrong side of the street, giving way to any pedestrians who may be present, and being doubly-paranoid at all driveway crossings. (A morally and legally superior solution is to walk the bike on this stretch of sidewalk.) If there is a signallized intersection farther down the road, you might consider overshooting your turn, making a u-turn (or using the crosswalk) at that intersection, then doubling back on the correct side of the street, to turn left onto your bikepath.
