How's it any different than literally any other intersection with a traffic light?
If they mark it like the do other intersections they like to leave at least one lane for ?
Take FDR at Rt 4 - heading north. You have a left turn lane, a left turn / straight lane and an unmarked lane (?)
One can safely assume that the unmarked right most lane is for right turns.
But it is also aligned with the right most lane on the other side of Rt 4. So is it a straight thru lane as well?
No a mark on the road or a sign over head. People in the middle lane seem to be confused if someone in the right lane goes straight across.
In this case I'm not faulty the drivers, merely an example of how SHA doesn't always make it clear.
