I guess you're limiting this to state routes with the same number as the Interstates, right? That would make this exercise more manageable.
How about I-195 -> VA 195 in Richmond?
I-381 VA, I-471 KY, I-540 NC, I-695 MD (officially), I-295 DC (if DC is a state)
I-10 FL looks like it does, but SR 10 is the hidden number for US 90 west of Jax.
Is I-215 NV the only one that continues as a county route?
edited–never mind, NE2 beat me to it. The board didn't trigger the "someone else posted" warning, oddly enough.
Unposted I-878 to NY-878 might be another, if you count unposted route numbers.
If you're willing to count provinces, then you have I-95 to New Brunswick Route 95.
New York has quite a few of these: 390, 590, 690, 890, 481. (NY 878 technically)
Would that segment of the San Bernardino Freeway between US 101 and I-5 count?
IL 255
Had it been built, the section of freeway extending west from the 380/280 interchange in San Bruno would have been California state route 380.
!-794 to WI 794 in Milwaukee.

And I-29 to MB 29 (very short connector in Emerson to the MB 75 highway to Winnipeg).
One could argue that the I-283/PA 283 (http://goo.gl/maps/Zy8Hk) hand-off is continuous.
Is 495 west of the LIE continuous? Wikipedia seems to imply that 34th street connext it to I-495 which in turn implies that it does not have that number where I-495 ends.

I-295 in DC continues as DC 295. One could argue that MD 295 could be that too, but the BW Parkway is unsigned and not exactly sure if MDSHA counts it as a hidden route 295 or not.

MD 295 begins at US 50; you have to use MD 201 to connect from DC 295 to MD 295. (The BW Parkway officially follows US 50 into DC, but MD 295 does not.)
I-105/SR 126 becomes SR 126 after crossing I-5 and heading east in Eugene-Springfield OR.

If 691 qualifies, there is also MA 25 seamlessly starting at the end of I-495. And depending on how you interpret it, there's MA 128 at the end of I-93. But I realize that's pushing it.

I believe the MB-29 designation has been eliminated, and 75 goes to the border to meet I-29. This is due to the closure of the U.S. 75 Noyes-Emerson border crossing. If you look at GSV, the road through Emerson, MB, which was where 75 turned, is now shown as MB-200 on the signs.

Well, if you're using the official, hidden routing for I-787, you also have to invalidate 690 and 890.
If we're allowing different number continuations, I-790 continues as NY 5 on both ends and also as NY 8 and NY 12 on its western end. I-587 continues as NY 28 on its western end and NY 32 on its eastern. I-678 becomes the Hutchinson River Parkway, and I-895 becomes E 177th St.

This is a bit less convoluted than you make it out to be.
For starters, the section of Kenilworth Ave between the DC line and US 50 has long been designated MD 201...that designation predates both DC 295 and predates that section of Kenilworth Ave being upgraded to a freeway.
Second, it's very debatable as to whether the NPS section of the Baltimore-Washington Pkwy even has a route designation.
Lastly, very few people call the lower part of the B-W Pkwy (from US 50 to roughly MD 175) by the 295 number. Most refer to the whole thing all the way to Baltimore as either the "Baltimore Washington Parkway" or call it the "B-W Parkway" for short. So there really isn't the confusion factor you suggest, either.

Quote from: shadyjay on February 28, 2014, 08:02:44 PM

I ask myself the same question all the time. My answer is that I didn't have a camera when I was a kid, and if I had developing the photos was expensive for a 10 year old and my parents were always broke. A roll of film held a fixed number of exposures, and you couldn't just look at the screen to see if the picture turned out OK. I wish the digital camera had come to market 30 years before it did, and if so I would have tens of thousands of now historic road pictures. A lot of us would.
Depending on your point of view, you could consider that I-84 continues West of Portland, OR as either US-26 or US-30. While is isn't a direct connection, due to the I-5/I-405 loop around downtown, there is a large amount of traffic that crosses the city from either US route to I-84.
I-90's Western Terminus continues as SR-519 in Seattle, which in turn continues as two state routes on the western ends of the ferry routes.
I-180 continues South of I-80 in Cheyenne as US 85.
I-182 continues East of Tri-Cities, WA as US 12 (SR-12)

The DC DOT recently made this 295 designation much simpler.
Until recently, I-295 started at the Beltway near the Wilson Bridge and then continued on the 11th Street Bridge into Downtown DC ending at I-395 in Capitol Hill. Meanwhile DC 295 started just before the 11th Street Bridge and headed towards the 50/BW interchange. So in essence in Anacostia, I-295 split into two separate routes: I-295 and DC 295.
But now that they've instituted the I-695 designation for the freeway connection between Anacostia and Capitol Hill, and 295 is one roadway.
To really simplify things, of course, they should convince the Nat'l Park Service to designate the BW Parkway as some kind of Federal-295.
In my view, I'd like all limited access highways (GW Pkwy, BW Pkwy, NYC area parkways, La Cienega Expressway in L.A.) to be designated with some kind of route number, even if it's not an official state highway. It will definitely ease navigation.
As far as 283 in Penn., there isn't as much confusion on the signage as there is on the map. I would also like to see I-283 extended to Lancaster and I would post the stub routes (connection to 230 and connection to the Turnpike) as two different state routes.
So if going southbound, I'll see I-283 to Lancaster but PA XXX to I-76 to Philly and Pittsburgh.

Is that really 393 "continuing"? None of those roads begin where 393 ends. Once you open that can of worms this thread just becomes "How many places are there where an Interstate ends at a state highway?"
QuoteUntil recently, I-295 started at the Beltway near the Wilson Bridge and then continued on the 11th Street Bridge into Downtown DC ending at I-395 in Capitol Hill.
Not quite correct there. The Southeast Freeway between I-395/3rd St Tunnel and the 11th St Bridge has always been I-695...just wasn't signed until recently. What I-295 did was cross the 11th St Bridge, then follow the Southeast Freeway stub to Pennsylvania Ave. I-295 was to have continued around the east side of RFK, then skirt northwest more or less along Mt. Olivet Rd NE to meet I-95 on top of today's Amtrak rail yard (north of US 50/New York Ave and east of the 9th St NE bridge).
Continuing the original topic trend...not the same number, but MN 61 begins where I-35 ends in Duluth, MN. And down in D'Iberville, MS, both MS 15 and MS 67 begin as a continuation of the I-110 roadway.
So, we have the following same number, signed, examples
AL 759
AR 440
CA 15
CA 110
CA 210
CA 238
DC 295
IL 255
NY 390
NY 481
NY 590
NY 690
NY 787
NY 890
PA 283
VA 195
WI 794
and there's Clark County 215 in NV
I'd imagine that IN 265 is our state's only one, SR 57 used to qualify but now that is of course I-69. Once the East End Bridge is finished then the SR 265 moniker goes away to become I-265.
QuoteSo, we have the following same number, signed, examples
NC 540 (mentioned earlier) missing from your list.

But TX-45 is within Austin, TX. I don't see any documents showing TX-45 at any point going to I-45. I am not sure how Texas DOT permit this to happen.
It happens in other places in Texas. such as I-20, TX 20 in El Paso three counties west of I-20's west end, and TX Loop 20 in Laredo far south of I-20.
And don't get me started on duplicate numbering between regular and loop/spur state routes, such as 360 in the Dallas area and Loop 360 in Austin, or 151 in San Antonio and Loop 151 in Texarkana.
TxDOT seems not to care in the least about number duplication, at least if the same-numbered routes are in different parts of the state.
I never thought of that because i noticed that in some parts of california have historic us routes like us40 in solano and sacramento that are now city managed streets thats because caltrans removed us40 because i40 was assigned to the mojave area.

No. Caltrans removed US 40 because their policy has generally been to move U.S. Routes to parallel freeways, and the freeway now had a new number.

I noticed that Texas has two roads designated as 45 , TX-45 and I-45

Lots of states "duplicate" numbers. They usually use the prefix to separate types of routes, i.e. I-96 and M-96; I-64 (FAI-64) and IL-64 (SBI-64); I-64 and IN-64 (SR-64); etc.
To be frank, I find the states that do not use numbers like that a bit odd.

62's a good example, but 101 is just two segments of a once-continuous route.

There's also KY 3215 (https://www.aaroads.com/forum/index.php?topic=4489.msg98630#msg98630): presumably two districts simultaneously used the same next available number and never fixed it.

Another failure; that's defined as one continuous route that was simply never built in the middle.
Going back to page two to address this question:

At the risk of taking the thread slightly off topic, I'd be curious how often an interstate dies this at both ends like 195 does (for now).
Nevada's I-580 continues as US-395 at the north end and ... some state route connector to US-395 at the south end (NV-431?)
Current south end is temporary US 50/395. Not sure what state route designation it has (431 is about 15 miles north)
At the south end, Nevada I-580 stops at the William Street/US 50 interchange, so the freeway continues as US 50/395 (it's the permanent alignment for those two highways, not a temporary one). The open segment of Carson City Freeway without I-580 doesn't have a state route designation (it is in the NDOT highway logs as US 50).
The temporary alignment of US 50/395 is along Fairview Drive, forming the connection between the end of the freeway and the old alignment on Carson Street. Fairview Drive is not a state highway (nor has it ever been). To my knowledge, it's the only place in Nevada where a signed US highway (technically a "Temporary" route, according to AASHTO) is not maintained by NDOT.

3? is that it? That's good going. Northern Ireland had 3 in its original numbering!
Britain has lots. (http://www.sabre-roads.org.uk/wiki/index.php?title=Duplicated_road_numbers)
I-280 near Toledo continues as SR 420, which in turn ends at U.S. Highways 20 & 23.
I-255 in Missouri/Illinois turns into Illinois Route 255 after intersecting I-270 in Pontoon Beach, IL. It maintains Interstate Highway standards.

(Also, I-495 does not at all connect to NY 495, unless you use FHWA definitions. NYSDOT's NY 495 is just the Lincoln Tunnel.)
Right, although this is an easy mistake to make because NY 495 is signed as I-495 in a batch of places, including on NY 9A. So, a road signed as I-495 (but really designated NY 495) turns into NJ 495.

I-229 in South Dakota turns into a dirt county road. it is numbered as "476th St." - does that count as a numbering? it should: the number is in accordance with an orderly and well-defined grid!
476th St is paved for the first 3 miles after the north end of I-229...
In the consolidated list above I-381 becoming VA 381 is missing
The Virginia CTB considered continuing I-464 as VA 464 but elected to make it VA 104 instead.

I-90 continues west from I-5/4th Avenue as WA-519 in Seattle.
I-405 continues west from I-5 in Southcenter as WA-518 as well as continuing north as WA-525 from I-5 in Alderwood/Lynnwood.
I-705 continues south as WA-7 from I-5 in Tacoma.
I-265 and IN-265 in Indiana, but probably only until late 2015 or early 2016 when it is joined to I-265 in KY

NY 690
NY 787
NY 890
PA 283
Technically no on all of these. I-690 and I-890 end at I-90, which are different points from where they meet NY 690 and NY 890. Likewise, the north end of I-787 turns and crosses the Hudson River, so NY 787 ends at I-787, but I-787 does not end at NY 787.
I-283 ends at I-76, not at PA 283. And PA 283 ends at the traffic light at the west end of the freeway, not at I-283. So that one's a double no!
QuoteTechnically no on all of these. I-690 and I-890 end at I-90, which are different points from where they meet NY 690 and NY 890.
True on I-890, but according to NYSDOT GIS shapefiles, I-690 does not extend onto the ramps to/from Exit 39. So in this case, I-690/NY 690 would be a "yes".

Tell CHM that. They have I-690 on those ramps.
I'm a CHM contributor...there are other factors at play with the CHM lists than what's strictly official or not.
Given all of the California examples, I'm surprised no one has mentioned I-880 turning into CA-17 south of I-280 in San Jose.
Illinois 394 in Northeastern Illinois. I 394 would be an appropriate spur name if it ever became an interstate.
The US route ones are fun, especially where the handoff from the US route to state or provincial route doesn't exist anymore thanks to a truncation (US 75 and MB 75; US 61 and MN 61, and the clincher, US 99 and BC 99).

But it really doesn't continue as a state route. The Calumet Expressway does, but I-94 makes a turn there.
Does I-74 to US 74 count in North Carolina? That's gotta be one of a kind

That would be just like I-41/US 41 in Illinois and Wisconsin.
