If I'm understanding correctly, that makes you a longer distance commuter who does not use any underpass that might exist in any full build scenario.

And/or maybe we could add a ramp from that connector road to Inner Belt Road near New Washington St along with a bridge from somewhere near the southernmost part of Inner Belt road to somewhere near Water St. Doing anything about the northbound direction might be harder (the obvious way to do a Gilmore Bridge connection would require a left turn across Gilmore Bridge traffic). But it also looks to me like this is another commuting pattern that does not use any Rutherford underpasses anyway.

And the Sullivan Sq underpass doesn't help those heading to North Station / Government Center from I-93 at points north of the Mystic, either, AFAICT. Maybe the Community College underpass does help those folks a bit.

So is there some good explanation somewhere of what significant traffic flow does use the northbound underpass at Sullivan? And is the southbound underpass at Sullivan believed to be useful for much of anything other than casino / produce center / etc traffic heading onto I-93 southbound? (Surely there aren't enough Haymarket vendors who buy at the Produce Center to justify an underpass just for them?)

Basic traffic management. Of course the underpass helps people coming in from the North off of I-93, because if takes some Route 99 traffic out of the Sullivan Square circle. Less traffic in the circle makes the bad design flow a bit better. (The former flyover helped even more, of course.)
