Memorial Dr @ N Eldridge Pkwy construction

does anyone know what the ultimate end goal for the construction at this intersection is? when it started i thought “oh, maybe they’re shortening the right lane so people stop using it to cut traffic,” but now it seems like they’re just turning it into a second thru lane and turning the leftmost lane into a turn-only lane… and the way it’s set up means now people will either use that left lane to cut traffic instead, or potentially hold up traffic trying to merge into the middle lane once they realize they’re in a turn-only lane. i don’t know much about road planning though, so am i missing something? or is this just terrible planning and a waste of tax dollars?
