With 4 to 3 road diets all the rage these days, I wonder how beneficial center turn lanes really are on less busy roads. Would a conversion (further road diet, ha ha) from 3 to 2 lanes, with BLs and only strategically located turn lanes (say at major intersections) be able to move traffic just as efficiently? Such conversion would require a minimum of land and money, and would make less busy high speed roads more bike friendly.
