Route that ends at another route with a consecutive number

[roadman65]

We have had a thread about consecutive route numbers that junction each other, but  never with one ending at another.   This here was inspired as I noticed that currently the north end of I-49 in Missouri is at I-435 which is concurrent with US 50 as well as I-470 that also ends with I-49 carrying also US 50 in the mix, that  means that Interstate 49 ends at its next higher number.   

Whether Kansas City ever gets I-49 through the city or not, it still actually has its furthest point north and end at US 50 in Grandview.  I do not think that we have

How often does this kind of thing happen?

Probably fairly common among clustered state routes. Off the top of my head, VA 2 ends at US 1 at one and VA 3 Business at the other.

[dgolub]

NY 105 and NY 106 end at each other.

[hotdogPi]

CT 2 at US 1
MA 13 at MA 12
MA 21 at US 20
NH 102 at NH 101
MA 105 at MA 106
MA 127 at MA 128

[roadman65]

MA seems to have a lot.   

[hotdogPi]

Iceland seems to have a ridiculous number of these. Not only is there clustering (the first two digits tell you pretty much exactly where on the island you are), but Iceland has no concurrencies, causing a LOT of short routes ending at other short routes.

[Mapmikey]

For Virginia:

(As noted above) VA 2 ends at US 1 or 1 Business on both ends and VA 3 Business on one.
VA 28 at US 29
VA 72 at VA 71
VA 99 at VA 100
VA 118 at VA 117
VA 137 and VA 138 share a common endpoint with each other at VA 40
VA 145 at VA 144
VA 237 at VA 236

There used to be way more back in the day...

Maryland's numbering system lends itself very well to this. For instance, MD 188 ends at MD 187 in Bethesda, while MD 191 ends at MD 190 a few miles west of there.

I don't think this would happen often in Texas, where the route numbers are mostly assigned consecutively.  Earlier designations didn't even specify a number as they do now; they just declared a highway designation of a certain type and the next available number was assigned administratively.  The only example I can think of is Spur 77 ending at Spur 78.  Spur 78 was designated in 1939 as the road to the McDonald Observatory. A new facility was built nearby later and in 1990 the short road from Spur 78 to that facility was designated as a spur, without a number specified.  The Loop 77 designation (Spurs and Loops share a number pool) had been cancelled in 1963 so that number was used for the new road.

Old Spur 72 was cancelled in 1983 and reassigned in 1987.  73, 74, 75, and 76 were all in use in 1990.  It appears that 77 just happened to be the lowest available number when the road was designated so the consecutive arrangement wasn't planned.

NY 31A ends at NY 31 

[Big John]

ND 22 ends at ND 23

[7/8]

In Ontario:

Highway 4's southern end is at Highway 3 near St. Thomas
Highway 5's eastern end is at Highway 6 in Hamilton
Highway 9's western end of the eastern half is at Highway 10 in Orangeville
Highway 65's western end is at Highway 66 near Matachewan
The 402's eastern end is at the 401 in London
The 416's northern end is at the 417 in Ottawa

[Charles2]

AL-216 ends at AL-215 in Tuscaloosa.

At one time, AL-79 ended at US-78 in Birmingham.

[US 89]

Utah tends to use a number clustering scheme for state routes, so there are a few:

UT 119 ends at UT 118 in Richfield.
UT 25 ends at UT 24 near Fish Lake.
UT 100 ends at UT 99 in Fillmore.
UT 43 ends at UT 44 in Manila.
UT 209 ends at UT 210 at the mouth of Little Cottonwood Canyon.
UT 105 ends at UT 106 in Centerville.
UT 162 ends at US 191, which according to UDOT internal route logs is also concurrent US 163.
At one time, UT 272 across US 89 from UT 273 (it was two RIROs) in Farmington. The RIROs were reconfigured to an interchange, and soon after, both routes were merged into 273.
UT 162 once ended at UT 163 near Pineview Reservoir (both routes have been decommissioned since)

And my favorite, UT 90 ends at the US 89/US 91 concurrency, with consecutive numbers on both sides.

I got one! CA-7 has its northern terminus at I-8

[TheHighwayMan3561]

MN 22's north terminus at MN 23.
MN 27 has its western terminus at MN 28 - and MN 28 has its eastern end on a duplex with MN 27.
MN 36's western terminus is at I-35W.
MN 43's southern terminus is at MN 44.
MN 67's eastern terminus is at MN 68.
MN 72's southern end is at US 71.
MN 96's eastern end is at MN 95.

There's also the famed Faribault intersection, but I'll let MNHM expound on that.

[TBKS1]

AR-265 ends at AR-264 in Springdale. That's the only one I know off the top of my head though.

[Hurricane Rex]

OR 27 begins at US 26. Does that Count?

[Max Rockatansky]

AZ 97 ends at AZ 96, AZ 61 ends at US 60, and AZ 86 ends at AZ 85.  The original Arizona numbering convention was that state route numbers were consecutive from US Route numbers.  That's why there is so many 60, 70, 80, and 90 state highways in the state.

[webny99]

OR 27 begins at US 26. Does that Count?

Well, of course, because it also ends at US 26 


NY 223 ends at NY 224
NY 60 ends at US 62. Close, though not directly consecutive.

[Henry]

If we're doing Interstates:

CURRENT
I-74 ends at I-75 in Cincinnati

FUTURE
I-11 may one day end at I-10 near Phoenix
I-86 may one day end at I-87 in Harriman, NY

But 21, 3, nor 60 are consecutive... oh.

For the unaware, the short institution-serving MN-298 and 299 share a terminus with MN-60. This post reminds me that this spring I should get pictures of those two routes–I'll probably do it on the same trip I'm going to take to capture the final days of MN-110. In that regard, spring can't get here soon enough.

Also, your post made me realize how weird it is that MN-27 and 28 are connected as they are. Huh.



Famously, at least in Iowa lore, Iowa 1 ends at Iowa 2.

[bzakharin]

NJ 28 ends at NJ 27, but not vice versa, so I don't know if it counts

[triplemultiplex]

WI 31 ends at WI 32
WI 33 ends at WI 32 (although that's the reverse of the OP's idea)
WI 44 ends at US 45

WI 52 used to end at US 51 but after the system interchange was built for WI 29 west and US 51, that end was moved to WI 29.

[MNHighwayMan]

WI 52 used to end at US 51 but after the system interchange was built for WI 29 west and US 51, that end was moved to WI 29.

This reminds me that Iowa 51's southern terminus is at US-18/52 in Postville.
