Exit number = Route number

[michravera]

Hi, so I was recently wondering something: how many freeway exits might there be with a number that's the same as that of the road the exit serves? I know of at least three:

• In Arkansas, I-40 Exit 64 leads to US 64 near Lamar.
• In Connecticut, I-91 Exit 5 serves US 5 in New Haven.
• In Indiana, I-65 Exit 50 accesses US 50 near Seymour.

What other such exits might there be around the country? I'd be interested to know.

There was at least one thread on this back in the m.t.r days.
The most obvious is likely to be exits on to CASR-1. California exits are numbered from the west and CASR-1 frequently runs as west as you can get.  The problem is that a number of freeways end before they get to it.

One example is Exit 1B (or is it 1A) for CASR-1 on CASR-17.

I-435 Exit 71A in the Grandview Triangle leads to US-71 South (plus I-470, I-49, and US-50). East/North I-435 has Exit 71B for US-71 NB.

A couple other close calls:

• I-35 Exit 76 for US-77 near El Dorado, KS.
• I-29 Exit 8 for MO-9 in Kansas City.

Louisiana's 2 are:

I-55 exit 40 is for LA 40 and Independence
I-49 exit 119 is for LA 119 and Cloutierville

Another IL near-miss example: Exit 58A is for 59th St off the Dan Ryan Expressway/I-90/94 on Chicago's South Side

[webny99]

Thruway Exit 59 is for NY 60.

For some reason, close ones (one number off) seem to be easier to find than actual examples, even though statistically they should occur with equal frequency.

Wouldn't it be double the frequency, since you can be off by +1 or −1?

Whoops... yep, of course. My bad.

Bloomfield Township, MI:

[amroad17]

I-77, Exit 52 for US 52 (and VA 42) in Bland, VA.

[US 89]

If you're coming from the south on I-25 in Springer, NM and you want US 412 east, you'll take exit 412. It's not a perfect example - US 412 ends at BL-25/old US 85 and doesn't actually intersect I-25 - but it's the first thing that came to mind.

Exit 1 for US 1 on Florida's Turnpike:


Exit 9 for US 9 on I-287:


Exit 1 for CR 1E on I-29 in North Dakota (while in South Dakota):


A close one on I-75 in Florida...Exit 414 for US 441 and 41:

[sprjus4]

I-264 Exit 13 for US-13 Military Hwy in Norfolk, VA.

[Roadrunner75]

Exit 1 for CR 1E on I-29 in North Dakota (while in South Dakota):

What's with the gate and the "closed when flashing" sign?  I don't see anything obvious - flooding problems at that culvert a little way down?

A close one on I-75 in Florida...Exit 414 for US 441 and 41:

That would be a fun one to include in directions - "Then get off exit 414 for 441 and 41...."

Not knowing the Dakotas as I have never traveled thru them...But interstates in that part of the country are known to have gates, basically for closing the road in blizzard-like conditions, I believe

I-75 Tennessee - Exit 11 (US 11/US 64), Exit 72 (TN 72)
I-185 Georgia - Exit 1 includes GA 1.

If km based mileposts and exit numbers are used, I-465 exit 70 would be for I-70.

[JoePCool14]

One for Illinois that wasn't previously mentioned is Exit 1 on I-94 for Russell Road, which now has signage labelling it Lake County A1. The exit really should labeled be Exit 0 though.

And this is definitely cheating, but US-20 can be accessed from Exit 20, Irene Road off I-90. It's a few hundred feet north of the interchange. The real exit for US-20, which that would also technically be cheating, is Exit 17.

Found one to a former state route alignment while browsing Quad Cities area roads: I-88 Exit 2 to Old IL 2

A few come to mind in South Carolina:

I-77, Exit 34: SC Route 34 https://www.google.com/maps/@34.3268205,-81.0057827,3a,53.1y,218.94h,89.35t/data=!3m6!1e1!3m4!1swpfLyzd_u2hpxyNpJ7-15A!2e0!7i16384!8i8192

I-77, Exit 41: Road 41

Fayetteville, AR  Exit 62 / US 62 (needs to be updated)

[SkyPesos]

An interesting case here: US 35 doesn't have a direct interchange with I-71, but it crosses it at MM 71. The two connector interchanges it has with OH 435 (the connector road to I-71) are exits 70 and 72.

 I-75 N Exit 25 ---> US-25W in Corbin, Kentucky

[bzakharin]

On the Garden State Parkway Exit 9 is signed "TO US 9", though, to be fair, so are exits 0, 11, 12, 13, 20, 25, 29, 48, 50, 80, 123, 125, 127, and 129.

If we're going to include near misses then US 30 is Exit 29 from I-295 in New Jersey, and you could access US 30 using Exit 30 if you really wanted, though I don't see why anyone would. Further north Exit 40 takes you to NJ 38 (there is no Exit 38).

Separately, NJ 47 parallels NJ 55 for the entire length of the latter. Unfortunately, there's no Exit 47, just 45 and 48. Similarly, US 30 parallels the Atlantic City Expressway, but there is no Exit 30, just 28 and 31/33 (depending on the direction).

Exit 2 on I-270 in Colorado is for CO2.

West Virginia has a number of "almosts".  Among them is Exit 79 on the West Virginia Turnpike, the Sharon exit for "fractional" CR-79/3.  The underpass for Sharon Hollow Road (CR-79/3) just happens to be located about halfway between Mile Marker 79 and Mile Marker 79.5, such that one could round that number up from 79.25 to 79.3.

If I-95 in Delaware had mileage-based exit number instead of sequential ones, the Delaware 7 NB & SB/Delaware 1 SB exit might well be Exit 7, depending on how Delaware would do those signs. I have seen many cases where the exit number didn't quite match the mileage (i.e., is exit 7 in the 7th mile (therefore between mileposts 6 and 7), or is exit 7 where the left most mileage number is 7 (and is therefore between mileposts 7 and 8 -- latter case might allow for Exit 0). And another thing that I've never seemed to figure out, where is the actual exit -- is it where the intersecting road physically crosses the other road?

For us older people from Delaware, that exit was always for Delaware 7 (NB and SB). Delaware 1 didn't come along until a couple decades later.
