I know that they're are plenty of places out there which a road for several miles that has one name up to a point just before the road ends it changes to another name for a very short distance.
In Orlando area in Florida you have Goldenrod Road that is the name of pretty much FL 551 for its entire length, yet just a few blocks before its northern terminus it changes to Palmetto Avenue.
In Middlesex County, NJ you have Roosevelt Avenue (Exit 12 off of the NJ Turnpike) that is that name for several miles, and just before the road comes to terminate at US 1 & 9 becomes Randolph Avenue for a few short city blocks.
We used to have Tropical Trail that was the section of now defunct Americana Boulevard under I-4. What is even more interesting is the fact that once the Millenia Development truncated Americana to John Young Parkway, Tropical Trail actually became its own street as it was a connector under I-4 from Millenia Boulevard to Vineland Road and once that happened the City of Orlando renamed it Radebaugh Way! After all these years Tropical Trail's name was legit and someone decided to name it to someone no one even heard of.
How about any others in your area perhaps that annoys you or not, that offsets a road's continuity that would be much better for everyone to not have that temporary designation and go the "whole 100 yards" so to speak.
Does it count if the name change is obviously due to a jurisdictional boundary?
Huntington Avenue in San Bruno and South San Francisco is 2.1 miles, while at the very north end past South Spruce Avenue, the road continues for just one block (with no buildings fronting it) as Terrace Drive.

Of course!
In Somerset County, New Jersey, CR 514 starts out as Amwell Road, then as you head east it becomes Old York Road once it crosses into Hunterdon County.
Hardy Parkway Street is signed as such for all of its length (about a mile) in the City of Columbus. At its north end, which is just slightly into unincorporated Franklin County, it's signed as Hardy Parkway.
Hayden Run Road has, for a long time, been a fairly long (about 6 miles) road in northwestern Franklin County and northeastern Madison County – with the same name in both counties – with its west end just east of Big Darby Creek, and its east end just east of the Scioto River at US 33. (For a few years in the early 20th century, the bridge over the Scioto was part of the state highway between Dublin and Columbus.) Bethel Road begins at US 33 just a bit south of there, and proceeds east. Sometime in the 70s, the City of Columbus (which had annexed this area by then) decided to realign Hayden Run Road so it ties in with Bethel Road. Hayden Run Road got a new, higher bridge on a slightly different alignment, but it still ends at US 33. Its extension, which curves southeast to tie in with Bethel Road, is for some reason called simply Hayden Road.
Plain City — Georgesville Road is a reasonably long road connecting Plain City with Georgesville (about 10 miles) along the west side of the Big Darby Creek. Most of it is in Madison County, where it's also county road 7, except where it's OH 142. The last mile and a half is in Franklin County, where it's called Gardner Road, and assigned a county road number that's like 274 or something like that.
Missouri 360.

The U.S./Canada border is the starting point of a whole lot of such extensions, then.
Before the completion of the rest of the Chesapeake Expressway, the Oak Grove connector was simply an extension of I-464.
If jurisdictional boundaries count, IL 35 is a very short extension of WI 35, Wisconsin's longest highway.
Arroyo Parkway as the surface street extension of the Arroyo Seco Parkway (née Pasadena Freeway)?
Washington SR-35, which is an extension over the Hood River Bridge of Oregon OR-35, is about 1/2 mile long, over the bridge to SR-14 (fka US 830).
I would consider CA-110 in relation to I-110 (or vise versa).
MA-295 is similar. it's an extension of NY-295.
it's also the only route number which is duplicated in MA. there is an I-295 on the other end of the state. MA generally avoids route number duplication to prevent confusion, but this case was deemed to be sufficiently unambiguous.

I'm pretty sure there's actually no such highway currently. The number is legislated, but only if a new crossing is built. The Washington approach to the current Hood River Bridge is not a state highway.
NH 108 has about a mile in Massachusetts as MA 108.
RI 15 has about a quarter of a mile in Massachusetts, as MA 15 (unsigned).
Going the other way, Connecticut has an unnumbered extension of MA 31 that is very short.
Maybe not "short", but MA 25 is a direct extension of I-495.
Similarly, the north end of I-95 continues into Canada as New Brunswick Route 95.

what was the number of this when MA-15 was an active route? (now I-84)
QuoteSimilarly, the north end of I-95 continues into Canada as New Brunswick Route 95.
is that the only interstate that keeps its number going into Canada? a lot of US routes do: 99, 97, 95, 395, 93, and also 75 and several others. 395 of those is the shortest: a brief connector to BC-3.
NC 38 is a short extension of SC 38.
NC 615 was an extension of VA SR 615 until Virginia Beach got rid of all of their SR's.
SC 179 is a short extension of NC 179 ( 0.62 mi ).
On Long Island, Peninsula Boulevard (Nassau CR 2) extends 9 miles before turning into Bay Boulevard (Nassau CR 2A) for all of one block.

I don't think Massachusetts signs 15, so it was probably just unnumbered.

There was a brief MB 29 between MB 75 and Pembina, ND....but that has since become part of MB 75, as US 75 no longer has a separate border crossing to the east.

Fitting perfectly in this topic, if it hasn't been mentioned already: ON 137 in relation to I-81.

I wouldn't be surprised if there's at least one street sign reading "Route 15," though I can't recall one. It's still a commonly used name locally.

referring to "RI 15 extension", or "what was before I-84"?
The RI legs of Route 114A in East Providence appear to be mere extensions of the MA (Seekonk) section.
West Orange, NJ: Pleasant Valley Way (which started life as Brookside Drive and Cherry Lane in South Mountain Reservation, but that's several miles ago) becomes Lakeside Drive in Verona. People still call it Pleasant Valley Way, though, to the point that a North Jersey meet included that in its meet instructions. Most people got lost, but I just turned there without even noticing that the street name was wrong.
I-95 is I-95 for most of its length from Florida to NJ, and then becomes I-295. :P

The signs there basically refer to RI 15.
NJ 413 in Burlington is a short extension (from PA to US 130) of the longer PA 413 on the Bristol side of the Burlington-Bristol Bridge.
TN 99 from I-65 to US 431 is a direct extension of US 412. Similarly, TN 69 from I-40 to US 412 is a direct extension of US 641. KY 79 is only 1-2 miles away from being a direct extension of US 79, and since it goes in the same direction I'd say it's an indirect extension. KY 79 is 104 miles long, so it's not short distance, but it is much shorter than US 79.

Not really. TN 99 was there long before US 412 came along, and is actually the hidden state route number for 412 between Hohenwald and I-65.
Many of New York's 3DI's continue as state routes with the same number beyond the end of their Interstate designations. For example, both Capital Region 3DI's do this: I-890/NY 890 and I-787/NY 787.
^As well as Syracuse's I-690/NY 690, I-481/NY 481, and Rochester's I-390/NY 390, I-590/NY 590.
