And there's a case where it was supposed to be a 3-digit Ring
interstate but got the 2-digit by default, due to cancellation of
other segments.  MA SR-128 (as relocated to freeway) would have been
one of three I-x95 rings, if i-95 had gone through Boston (unbuilt)
with an Inner Ring (unbuilt), as planned. Instead, I-93 (planned to
end at Boston) was extended south, along US-3 freeway, and then
perversely around MA-128 to where I-95 departs ring MA-128 south.
     At that junction, a car traveling MA-128 S counter-clockwise from
Gloucester end to Braintree end will shift from I-95 S / MA-128 S /
US-1 N  to I-93 N / MA-128 S / US-1 N, while compass says they're
still going South-East!

   (US-1 used to go straight through, on Metro.Dist.Comm. Parkways, a
diagonal arterial across Olmsted's Emerald Necklace, but the US Route
1 was relocated to the freeways recently, so US-1 runs S along MA-128N
a couple exits further than i-93 S. There is a rumor that one US-1
shield remains on the old route. AFAIK old-one isn't even signed ALT
or 1A or Old 1 :-(  )
