(Eastbound I-291/Eastbound US-20; Springfield, MA)
I-291 (MA) cuts through
Springfield, connecting I-91 with the I-90 tollway. Interestingly, the
route's northern-terminus is not at Interstate 90; instead, it ends arbitrarily
at a set of stop-lights which provide entrance-ramps to I-90. The entire
length of I-290 concurs with a duplex of US-20.
Interestingly above, the shield-assembly refers to US-20 instead of an
"MA-20" marker.
