According to the 1968 MassDPW Recommended Highway and Transit Plan, the Middle Circumferential Corridor would've served less than 50,000 vehicles per day.

That's not nearly enough to justify a freeway.
Yes it is. 50,000 will justify a freeway in most states. It's at least a 4-lane highway out here.

That whole book is depressing. Red Line and Orange Line to 128, Blue Line to Salem, Rt 209, upgraded 128 to Gloucester. There are a dozen+ things in there that didn't happen at a minimum.

They were forecasting a population boom in the Boston area that never materialized. They ignored how the gas tax would be eroded by inflation. They also drew lines on maps without detailed studies that would've probably turned up steep slopes and wetlands.

209 definitely falls into the wetlands problem. If 109 wasn't there I feel that would be a problem being built now in Millis and Medfield.

If Volpe hadn't joined the Nixon administration, quite a bit of that would likely have been built.  Enourmous mistakes were made in the 1970 timeframe.

50,000 AADT is certainly enough to warrant a freeway, and may be close to 6 lane warrants depending on peak traffic flows, and would likely carry higher volumes now, in 2023, had it been built.

495 isn't really a circumferential of Boston southeast of Foxborough, or arguably southeast of the Mass Pike.  It would be if a ton of traffic was generated from Cape Cod, but Cape Cod is quite decidedly not a dense urban core generating a massive amount of traffic.  It generates a good amount, yes, but not a ton. 495 does serve a good purpose in its southeastern reaches, though, providing access to a lot of populated areas in southeastern Mass. And 495 is a suitable enough number, as the majority of the highway serves as a bypass.  My point is that Boston, more or less, has 1 1/2 bypasses rather than 2. (Same with I-355 in Chicagoland; I'm hesitant to call that a bypass.) I'd be more inclined to call the southern half of 495 a bypass if there was a highway running south from Wareham or Cape Cod south across the ocean to, say, the Hamptons?  :-P

Sorry, but no. For one thing, 495 very much is a bypass all the way down. Prior to the completion of 495 to the Bourne Bridge, from the west you pretty much had to go 90->128->3.  And that was hell. Now, yes, you're bypassing Boston on 128 (now 95) as well - but the bypass is of the densely populated Boston inner suburbs and 495 does that well. Also, I've had the pleasure of traveling between NH and Cape Cod a time or two and you have 3 choices: MA 3->93 through downtown (horrible traffic), MA 3 -> 93/95/128->MA 3 (bad traffic) or 495 -> US  (traffic usually moving). I've done #1 in the middle of the night, #2 late a night and #3 the rest of the time.

Also, your comment about 355 isn't correct either. It is also a bypass of sorts, providing a routing between the NW suburbs and points south. Were it not there, tens of thousands of cars would be heading to the Eisenhower (290) and on to the Tri State rather than staying on 355. Just because the bypass doesn't bypass downtown does not mean that it's not a bypass, Both examples above involve freeways to do indeed bypass very heavily traveled and congested areas that are every bit as busy as the center of a mid-sized city.

There is no rule that odd-numbered first-digit three-digit Interstate Highways can't end at another Interstate at both ends.

Well obviously when a state runs out of even numbers for the first digit of loop/circumferential routes, they're allowed to use odd numbers for the first digit of additional such routes. That doesn't disprove the existence of such a rule.
Control cities CAN be off the route! Control cities make NO sense if signs end before the city is reached!

50K AADT is enough to build a freeway connection, if you're someplace like Phoenix. With someplace as densely populated as Boston, it's not nearly enough to spend multiple billions of dollars on just property acquisition for the freeway.

The thing about Cape traffic is that it is extremely variable, light most of the time but huge on summer weekends. It's not sufficient to look at AADT. They should probably compute the RMS of the traffic instead, which would weight the busier times more heavily.

So that extension feels like an odd 3DI, because it's going to something rather than around it. But for most of its distance it feels like an even 3DI because it is primarily going around Boston. The only city over 100K on its route is Lowell, and no one thinks of 495 as the Lowell road, except locally.

That's a non-answer

The question is, what are states allowed to do, or what *should* states do, if they run out of even-first-digit 3di numbers, but they build more 3dis. Interstate designation is valuable because interstate standards are higher than state route standards generally.

Some people think they shouldn't be allowed to use odd-first-digit 3di numbers.

That is incorrect, and I am right about that, and unless someone shows me a legitimate reference that I am incorrect about that, then I will treat it as me being right about that.

At one point, 495 was exclusively circumferential, ending at its current interchange at I-95 in Mansfield. IIRC, it wasn't until the 1980s that it was extended to Taunton at MA-24 and then down to its terminus with MA-25 and I-195 in Wareham. 

hotdogPi

The southern portion of I-495 is no less circumferential than the northern third (I-495 north of MA 2). Both segments are roughly straight lines, where the endpoint of the route is farther from Boston than the western end of the segment.
Clinched, minus I-93 (I'm missing a few miles and my file is incorrect)

Traveled, plus US 13, 44, and 50, and several state routes

I will be in Burlington VT for the eclipse.

Michigan has as well. We have several freeways here that aren't Interstates.

Show me one state that has run out of numbers that is planning on building another Interstate that would need to use a 3di number. California has used up all the I-x80's but they have no plans on building anymore I-x80's; the numbers get reused by state, no state is that large that they are going to run out of numbers that easily and for the most part the state's that are large like that don't need a large number of 3dis. And also something that has already been mentioned, not every freeway needs to be an Interstate.

Michigan is a state that isn't going to run out of numbers, in fact they aren't going to be building anymore Interstates and in a few years one of the numbers that are currently in use will become available again as Michigan is eliminating an Interstate in Detroit. I-75 most certainly won't use up all the numbers, I-96 won't either, neither will I-94 and I-69 doesn't even have any 3dis in the state.
