The Lodge north to I-94 west ramp is a pretty funky design, as you are leaving a left lane and entering on another left lane. The sight lines are pretty short, so the ramp traffic slows considerably before entering I-94.

When the detour plan was put together for the Gateway Project, traffic simulations showed that congestion improved with the ramp closed. With it open, the funky design lead to a lot of weaving on the Lodge and additional backups on I-94.
