Motorways can have RIRO maybe you should research

Also some of these edits were proper

I disagree with everything except ocean parkway. If this is your standard than all parkways should be downgraded to trunk. They all have right in ramps. Who said motorways have to be continuous.

in progress

Trunk road must form a network with other trunk and motorways. That would end at a primary road which is incorrect

That does not matter. Under state specific classification guidelines on the 2021 classification page, Mass classification is based on mass GIs functional classification. There is a reference there to a discussion where this was widely supported.

The entirety or US 3 is a trunk road. It is a major route.

A trunk road does not need expressway feature

No this not correct please use the ma state guidelines under the state specific guidelines on the same page you are looking

A trunk link has different classification than trunk road

Please stop

It is a trunk road based on the MA specific guidelines. Functional class 2. An expressway does not mean limited access.
