Connecticut has routes bearing every integer from 1 to 12, but no Route 13 perhaps due to superstition. What is the lowest unused route number in your state or province? Would be interesting to see which state has the highest lowest such number.
Interstate, US, state, county routes all count, but not numbered city streets.
Apologies if this has been asked before. I did a search and came up empty.
1, 3, 4, 5, 6, 7, 9 in Wisconsin
In Arizona, there are no single digit routes other than Interstate 8, and no double-digit routes lower than 60, other than I-10, I-11 (not yet built), I-15, I-17, I-19, AZ 24, AZ 30 (not yet built)), I-40, and AZ 51. AZ 48 and AZ 50 were proposed but never commissioned. County and Indian routes are not included.
Someone can just check TM and be done with this.
PA's is currently 2.
In Hawaii, 4 (4-10 were reserved for new Interstates, including the very short-lived Interstate H-4 proposal in Honolulu, and a never-built state ferry system).
In Alaska, 12.
In California, decommissioned 21, 30, 31, and 42, and others with higher numbers. As with Arizona, I'm not including Indian and county routes, which Travel Mapping doesn't cover. However, AFAIK there are California county routes 21, 30, 31, and 42, but not 48. US 48 existed in California about a century ago, and there is a proposed CA 48 that seems to be going nowhere. So 48 seems to be the lowest route number now in existence in California.
MN, decommissioned and not currently in use is 17.
For routes that have never existed, I believe 125.
AR-2 was replaced by US-82 way back in 1932.
Wikipedia is your friend on this one.
No route 9 in Maryland, although MD 9 was supposed to assume US 140 from Reisterstown to the PA line and even made a state map.
I believe it's 12 for Virginia.
Indiana: 21 (replaced with US 35 and SR 19)
Illinois: 11 (replaced with US 40 and IL-140)
Michigan: 4 (replaced with M-10)
Alabama: 58, hidden routes aren't counted (they're shown on ALDOT Milepost Maps). SR 58 was decommissioned about 10 years ago.
If hidden route numbers don't count, then 1 is the lowest.
214 has never been used in Alabama for a state route.

If we're counting county roads, you could probably get to 500 or more.
In Massachusetts it's 17. There is technically a MA 15 but it's unsigned and only runs for 0.2 miles from Rhode Island.
For NY, assuming we exclude county routes, it's 47.
For NJ, surprisingly its 2 (NJ-17's previous number). Note that US and Interstates are part of the same numbering system as state highways in NJ, so 1 = US 1.

Not counting provincial and other routes, it's 3. In fact 1 is the only number below 116 currently in use as a regional route, and counting national routes 2, 21, 22, 23, 40 and 68 are the only others below 100.
Quote from: Hunty2022 on September 12, 2024, 09:05:15 PMI believe it's 12 for Virginia.
This is currently correct. Best I can tell, the lowest number never used for a primary route in Virginia is 446.
Currently for SC it is 13. Best I can tell, the lowest number never used for a primary route in SC is 74.
Currently for NC it is 6. Best I can tell, the lowest number never used for a primary route in NC is 139.

Some of us also remember when MA 15 had an exit on the Turnpike.
Delaware's, I think, is 11.

It is 19. DE 11 does exist. I do think DE 9 should have been renumbered to DE 19 when US 9 made it to DE.
No current 4 in Colorado.
Surprisingly, the lowest number to never exist in Colorado is 405. Not counting county routes since I have no idea where to find an inventory of them. Also no national forest roads.
Not my state, but New Hampshire doesn't have a 5, 6, 7, or 8. The lowest route number it has that isn't a US route, a duplicate of a US route number (i.e. 4), or one of the original New England routes is 13, and even that goes into two states.
The lowest existing single-state route in New Hampshire, not counting letter-suffixed routes, is 27.
Massachusetts, New Hampshire, Vermont, and Rhode Island have a whole bunch of low 1xx routes starting with 101. The lowest to not exist in Massachusetts is 144, NH is 105 (although VT 105 ends at the state line) with 131 in second place, VT is 115, and RI is 105.
Ontario has never had a Highway 1, with the next lowest one being Highway 13.
For Utah: 1. State route numbers 1 through 5 used to be unsigned designations for the state's five interstates before 1977.
The lowest that's never existed at all in the state is 321.

I don't know where DE 11 is, it may be one of the more obscure routes downstate (like DE 5).
Something I've found, trying to work with DelDOT, is that they primarily use the "county" number internally. Those numbers are much less likely to change over the years, while state routes do change from time to time.
Illinois is missing an 11. From there, Illinois also doesn't have a 27, 28, 42, 44, or 46. (I'll stop at 50.) I'm actually impressed that New York State didn't skip a number all the way until 47, as Miss Deane has pointed out. :clap:
And just because it's
nice to know, for Ohio, the number would be 69, if it weren't for a lack of Route 1.

Delaware 11 is a real thing, and I have even driven on it. It runs southwest from Kenton to the Maryland border. (Photo taken at the state line.)

The lowest currently unused highway number in North Dakota is 7. ND 7 was changed to ND 200 to create the multi-state route 200. The lowest number to never have been used in ND is 70. Wikipedia says there was an ND 64 at some point but with no further details.
Quote from: Big John on September 12, 2024, 06:00:48 PM1, 3, 4, 5, 6, 7, 9 in Wisconsin
Since Wisconsin only uses two and three digit highway numbers (the singles are USHs), the lowest number two digit highway not in use in Wisconsin is 62. WI-62 was a short highway in Milwaukee County, decommissioned in 1999. Historically every two-digit number has been used at least once.
For Kentucky, it's 50 -- although I have seen old maps that indicate that KY 50 once ran on what is now US 421 between Lexington and Frankfort.
For West Virginia, it's 1 for state routes, although there are county routes with that number.
Always surprising when KY misses a number.

4?
The lowest route numbers currently not in use in Michigan are 4, 7 and 9, although each of them were used previously and have since been decommissioned. 7 and 9 were taken out of use in 1940 when the state opted to reserve single-digit numbers for an intended network of state trunkline superhighways. 4 was used as recently as 1986 on a segment of Northwestern Highway, but was renumbered as part of M-10.
The lowest number that has never been used in Michigan is 128 (according to MichiganHighways.org.)

And NY 47 was a thing until around 1980 or so (it was superseded by 390 and 590). I started looking for the lowest to never exist on the NY Routes website and stopped after getting through the 150s because I didn't want to click through that many pages.

Everything in North America has been copied over for a while now. rschen7754 is slowly chewing through the rest of the world—he's the real MVP when it comes to that.
Thanks everyone for interesting discussion. It seems there are so many variables - blocks of low numbers excluded, former routes, so many county routes - that it's hard to have a definitive answer to which state has the most consecutive route numbers starting at 1.
I think the current answer for New York is 323. State route has been decommissioned and I can't seem to find a CR-323 anywhere. All other missing SR numbers have CR's.
445 appears to be the lowest SR number never assigned.

It became MA 121 in the mid 1960s. It was in Wrentham
Since the OP started with my home state, I'll take the next closest that hasn't been discussed: RI, which is 8.
Iowa does not currently have a highway 11.
Nebraska does not have a Highway 3, as that was swallowed up by US 136 in the 60's
No VT 1, nor do I believe one has ever been in existence.
Quote from: hbelkins on September 13, 2024, 02:03:55 PMFor West Virginia, it's 1 for state routes, although there are county routes with that number.
Indeed, but the original WV-1 was an important historical route that crossed over into Maryland and back into West Virginia. Most of the original WV-1 became US-50 (and the WV-1 route was decommissioned for good), but ironically, US-50 was rerouted onto that missing section of the former WV-1 such that all of the original route eventually got promoted.
The lowest number not ever utilized in West Virginia is 110. The lowest decade never utilized is the entire 170s. Note that some of these numbers may have been used internally, as there have been a bunch of primary state routes that never got a route number (and were shown on official maps with rectangular state route symbols with no number inside).
It's 12 in Oklahoma. I'm not sure what the lowest number that was never used was.
For Florida, currently it's 27. There was a SR 27 for many years, but it was renumbered to 997 to avoid confusion with US 27. The lowest number to never have been used is 28.
I'm aware there is currently no SR 1, but I consider A1A as filling that role.

There has never been a WV 96, which I find odd because there have been 4 different WV 94's.
Since part of the topic is "lowest number that has never existed in your state"...
For California (explicitly excluding the never-used-in-the-field Legislative Route Numbers from the 1910s-1964):
Lowest number that never was built, but was indeed proposed: 64 (the Whitnall Freeway proposals of the 1960s)
Lowest number that was not ever used as a signed route number or as a proposed route: 272

I can't find any record of a route numbered 72 in Indiana. The only two lower unused numbers, 21 and 34, existed and were replaced by US 35 and 136.
North Carolina currently does not have a highway 6, while the lowest number never used at all is 139.

The 1978 state highway map (https://www.dot.nv.gov/home/showdocument?id=1259) shows both the old and new numbers. Some old numbers had already been removed (example: SR 1 became US 40).
Louisiana's lowest unused number is 7.

You have WV listed twice. Maybe the first one was supposed to be WI. Or maybe WY, which is also 1 and not on your list. NM is 5.
WV has a 2 so that is already incorrect.
Georgia appears to have every state route number up through 68, so 69 is the lowest currently unused one.
