Exits 20 and 25 are centered where their respective ramps meet the mainline.
Do you mean you fixed them on your end? Exit #20 clearly needs it recentered at the overpass for sure, as it's a normal diamond on the WB side.
As for Exit #25, it should be done the same way as 'AppRd' on nearby US-20, as it's the exact same type of interchange. When you also compare it to Exit #36 (which is the exactly same style), it should be done the same way. Especially since it isn't a trumpet type interchange normally seen on Toll Roads.
