Exit number = Route number

[CobaltYoshi27]

Not sure if this counts, but exit M7 the Meadowbrook State Parkway in Nassau County, New York (the M stands for Meadowbrook; the Wantagh State (W), Robert Moses Causeway (RM), Sagtikos State (S), Sunken Meadow State (SM), and the Bethpage State (B)  do this with their exit labels) is unsigned Nassau County Route 7A.

[national highway 1]

In California, several highways that end at State Route 1 should have the exit to State Route 1 also signed as Exit 1 (or a suffixed version of Exit 1).  Ones that are known to be signed as such:

I-10 (suffixed)
I-105 (suffixed)
CA-17 (suffixed)
CA-55

Here's CA 55 southbound at exit 1 for CA 1, the PCH at Newport Beach.

Greensboro had one that actually was before the renumbering and one that would have been had a highway not be realigned twenty years prior.

When I-40 was routed along what is now I-73 between 840 and 85, US 220 southbound was exit 220 (It's now exit 95 for I-73/US 220 Southbound)

When I-40 was rerouted through Death Valley in 2008, Randleman Road became Exit 220.  Randleman Road south of I-85 (40 ended at that junction) was US 220 until 1982.

In California on I-10 Eastbound at the "Other Desert Cities" Sign CA 111 is exit #111.

The exits from CASR-17 onto CASR-1 are Exit 1A and 1B.

[Walleye2013]

On Interstate 480 in Ohio, Exit 17B going westbound is for OH 17.

I-465 Exit 31: US 31 N

I-465 Exit 31: US 31 N

That's the third time this one has been mentioned in this thread (not counting when the citation was quoted). It appeared previously in replies 23 and 79. I don't know if there is a prize for being third. A bronze medal?

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.

[Roadrunner75]

So close!

And if you look at the mile marker next to the exit signage and its proximity to the actual junction, it looks like they missed an opportunity to avoid some OCD moments!

I know we've done this thread before, but there are more in Indiana:

Exit 25 on I-74 is for IN 25
Exit 31 on I-465 is for US 31
Exit 37 on I-465 is for IN 37 (in addition to I-69)

[Flint1979]

M-37 off I-96 is off by one exit number. It's exit 38.
Then a little further east M-50 is at exit 52, M-66 is exit 67 and M-99 is at exit 101. I don't think there is an example in Michigan that matches. These are the closest I can think of not exact but very close.

Here's a few Illinois ones, plus a few close calls and oddities.

Exit Number = Route Number
Exit 47 for IL-47 on I-90
Exit 59 for IL-59 on I-90
Exit 6 for US-6 on I-294

Near Misses and Other Interesting Stuff
Exit 145 for US-45 on I-80.  100 + the route number.
Exit 261 for IL-126 on I-55.  Anagram of the route number.
Exit 21 for IL-22 on I-94
Exit 5 for US-6/I-280 on I-74
Exit 217 for IL-17 on I-55.  200 + the route number.
Exit 41 for IL-40 on I-88

[jmacswimmer]

I-895 exit 1 for US 1 South, which I think is the only one in Maryland.

Two other near-misses:
-I-495 exit 30 for US 29
-I-695 exit 3 for MD 2

[jp the roadgeek]

Another one in CT: I-84 Exit 7 is for US 7 North (and US 202 East).  It marks the east/north end of the I-84/US 6/US 7/US 202 quadplex.  I-91 Exit 10 used to be labeled "TO CT 10" before CT 40 was commissioned. 

And if MassDOT played by the rules with its exit renumbering, the exits on MA 2 for I-95/MA 128 would be Exit 128 A-B

In the STL Metro East area of IL:
Exit 3 on I-270 is for IL 3

Exit 3 on I-55/64/70 includes signage for IL 3

IL 3 is Exit 6 on I-255, only a lilttle off

IL 3 is Exit 1 on I-57 at Cairo. Close.

There is a bit of a theme for IL 3, as it essentially parallels the Mississippi River in Southern IL, and therefore is close to the final exit South and/or West point for IL Interstates it crosses

Back up in Chicagoland, IL 1 is Exit 2 on the Tri-State/I-80/294

Also in the Quad Cities, IL 5 is Exit 4 on I-74

MS 57 on Exit 57 of I-10

[roadman65]

Exit 33 E Bound on I-4 in Lakeland, FL connects to FL 33.

[crispy93]

This happens 2.5 times on I-87.

Thruway Exit 9 in Tarrytown, NY for US 9
Northway Exit 7 in Latham for NY 7
Northway Exit 9 is for NY 146 but US 9 is accessible 1000 feet east of the interchange, though US 9 isn't on the sign

[vegas1962]

Another close one in Michigan is I-69 exit 13 which leads to US-12 Michigan Ave. near Coldwater.

[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.

[SectorZ]

In my very town, I-495 exit 38 is also MA 38. Not for much longer though.

[Ben114]

In my very town, I-495 exit 38 is also MA 38. Not for much longer though.

Also in MA, I-95 exit 1 is for US 1 (and it'll stay that way)

[CtrlAltDel]

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?

[dvferyance]

This has already been previously discussed several times. Ones not mentioned are Exit 25 KY I-75 US 25E and Exit 75 I-64 for I-75 north posted EB only. I don't believe Wisconsin has any one near miss though I-43 and US 14 is Exit 15.
