Interstates that Terminate at signalized Intersections

[dbz77]

Interstate 89 in Bow, NH.

It ends at Canada in Vermont and I-93 in NH.

No, it continues just past I-93 to the next intersection.

Per NHDOT, that extension to NH 3A is considered a ramp and is not part of I-89 proper.

Interesting, since so many people who live in the Concord area think otherwise.

If we pretend it follows the E Street Expressway routing, I-66 at 20th St NW in DC.

I-83 in Baltimore
I-795 at its northern end
I-676 at Franklin Square

Nope.  Officially merges into MD 140.  The MD 30 portion of the northern split is technically an exit.

I-710 North end in Alhambra, CA with Valley, Blvd has signals.

Note I-710 was supposed to connect to CA-710, CA-134 and I-210 in Pasadena.

Surprised no one has erroneously nominated I-471 in Kentucky.

The freeway ends at a traffic light at US 27, but the segment between US 27 and I-275 is officially unsigned KY 471.

[mgk920]

Much the opposite of I-96, the south end of I-19 (Nogales, AZ) is at a normal city street intersection (West St), but it is controlled with common STOP signs (West St stops for I-19).  There are not even any official AZDOT signs ON I-19 there either marking its beginning nor end.

I was going to mention it but wasn't sure if I-471 ends at US 27 or I-275. Thought it ended at the latter, and the section between US 27 and I-275 is purely a ramp.

I thought I-19 ended randomly at Crawford Street, not West Street.

Where is I-26's official eastern end? I don't think it's at one of the stoplights though.

[US 89]

Might depend on whom you ask. Per FHWA, the interstate designation ends at the Coming St intersection (stoplight), but SCDOT's map looks like they consider it to end at that left exit to Sheppard St.

[LM117]

To split hairs, while the south end of I-795 in NC technically ends at the US-70 interchange in Goldsboro, the actual freeway ends immediately south of there at the Ash Street intersection...at least until I-795 is extended south along the US-117 corridor to I-40 in Faison.

[dvferyance]

I-79 in Erie PA.

[roadman65]

I-78 should really end at a signalized intersection and not go through them.

It should end at Jersey Avenue where the NJ Turnpike ends.  If need be a number create a Business Spur I-78 like SC would do to go through the Holland Tunnel.

I-291 in Chicopee, MA
I-990 in Buffalo, NY

We sure about I-291?

I thought I-19 ended randomly at Crawford Street, not West Street.

In fact, AZDOT does have an overhead BGS at the interchange that is a short distance North (west) of West St (actually a blue stripe at the bottom of it) that warns of an upcoming signalized intersection and to be prepared to stop at it, but it is in fact the 'clear' side of a STOP sign protected intersection (West St) with progressively reduced speed limits.  Crawford St is past a funky, uncontrolled 90 degree intersection left turn about a block later (the streets here have sidewalks, too) and then ahead one more block to a STOP sign controlled intersection.  The main traffic flow between I-19 to the north and the border checkpoint a couple of blocks further along turns right here (southbound).  (Does I-19 officially continue through those two intersections?)

This is all per Google aerial and streetview images as of this morning.

I had said it earlier. And yes there is a signal at the Mass Pike entrance ramp as I-291 becomes Burnett Rd.

According to Google Maps, I-19 continues to a traffic light at Crawford Street and South Grand Avenue (Historic US 89), with a Business Loop branching off to the north on the latter street.

I-175 in St. Pete.

Also, I-375 to the north. There's a reason why they're called twin spurs.

I am thinking I-290 transitioning to Congress Parkway/Ida Wells Dr, but I believe the transition hits the Draw Bridge to end the Interstate before a Traffic Signal

So almost I-290/IL

I-72 I think officially ends at I-57 and the "highway"  in/out of Champaign is a glorified University Ave/EB&Church St/WB Feeder ramp pair, but I-72 originates/terminates at stoplights in Champaign

[Joe The Dragon]

I-65 used to at the I-90 ramp But now does at US 12 / US 20?

[Hobart]

I-65 used to at the I-90 ramp But now does at US 12 / US 20?

The last INDOT posted mile marker for I-65 is right before the signal at US 12 and US 20.
It is worth mentioning that there is a gap on southbound I-65 at this point, because there's an at-grade left turn there.

[JoePCool14]

The old southern terminus for I-43 arguably ended at the first signal west of I-39/I-90. But that's definitely gone now.

Edit: I would say this old milepost confirms it.

It ended at the old, obsolete  tight cloverleaf interchange at I-39/90.  Beyond that interchange, it was and is still WI 81.

Understandable confusion, because KYTC has signed that portion as I-471.

The west end of I-8 San Diego at Sunset Cliffs Blvd is signalized.
