It's kind of like the old saying, "the letter [of the law] kills, but the Spirit gives life." There really needs to be another light (as is suggested by the manual Table 4D-1, p.461 for 3 through lanes traveling over 45mph), at the intersection in the lane closest to the turn lane, and the light configuration on the power wires would be practical as the double asterisk suggest from the table. I'm still of the notion that the slick engineer sort of dropped the ball on this move, making an efficient intersection less efficient for the user. Had he put in the light when taking down the sign, or better yet added the concrete triangular island as there is certainly plenty of room for one, I'd commend him; but this is regress.
