intersections at IH-35 always seem to make long delays to cross the highway, sitting thru 3 or so light rotations (e.g. Wm Cannon! ugh!) I wonder if some intersections could be such that to cross IH-35 you turn right (with dedicated lane) merge left and go down 1/8 mile to a U-turn under/over highway. Come back to the desired road and turn right. If you need to turn left you too would get on the frontage road and make the U-turn. Limitation would be it would require space to give dedicated lanes to thru traffic and to turning traffic to keep all moving. Might it work in some places?
