When I have a 6 lane roadway that underpasses a maxis freeway, it'll do this (what's shown in the pic)Anybody know of anyway to fix this?

There may be a puzzle piece.  Also, it can be helpful to have a starter piece as close to the underpass as possible on both sides.  And then just keep clicking away until it fixes, that'll sometimes fix it.

 

Although I'm not completely sure about NWM under MHWY.  I never use MHWY any more.

You'll get the attention of the developers in that forum sooner.

None of the NWM networks have been made to cross under diagonal elevated Maxis highways.

 

Also your TuLEP intersection below will not work as intended. That setup is for avenue/avenue, not avenue/Road-6. If you made a Ave-6 or TLA-7, TuLEPs exist for those networks crossing avenues.
