One exit for two or more routes that are not multiplexed

[BrianP]

I noticed this one exit on US 35 in Ohio is for US 22 and 62.  But US 22 and 62 are not multiplexed.  OH 3 and US 22 are interchangeable since they are multiplexed.  But neither counts as a third route because of the multiplex.

The route numbers have to be signed on the exit.  Saying there's another route nearby doesn't count.  Route numbers labelled with 'To' are not directly served by the interchange and don't count.  And the route has to cross the freeway.  Using routes that parallel the freeway don't count.  No secondary routes either.  Just trying to avoid too many examples.

So any other examples?

Does this example in Cairo, IL count? https://www.google.com/maps/@37.0484609,-89.2001734,3a,47.6y,204.38h,89.65t/data=!3m6!1e1!3m4!1szKGBsJSjKGPb0d1N50_mlA!2e0!7i13312!8i6656

IL 3 is alone north/west of the interchange, but I guess IL 3 does multiplex with US 51 south/east to the IL 37 intersection...this seems like a completely unnecessary multiplex, tho - probably because IL 37 carried Old US 51

In Indiana:

I-64 near New Albany has an exit for IN 62 and IN 64 that go opposite directions from the exit.

I-69 at Fort Wayne has an exit for US 30 one direction and IN 930 the other.

I-80/90 near Middlebury has an exit for US 131 NB and IN 13 SB.

I-80/94 at Hammond has an exit for US 41 NB and IN 152 SB.

I think there are a number of examples that technically qualify according to the specific terms you've outlined (depending on what exactly you mean by "secondary" ), although I don't think they truly fit the spirit of what you're looking for.

For example, many of the Pennsylvania Turnpike's interchanges sign multiple route numbers (without a "TO" ) that are accessible from the exit–even though the Turnpike ramps only connect with one of them directly. Examples include Carlisle, Lehigh Valley, and Pocono.

Might Cranberry, which is signed for both I-79 and US 19 and has direct connections to both, qualify both in letter and spirit?

Once-upon-a-time:  Its technically two exits, but Exit 222 and Exit 223 for I-40 in Greensboro are entangled together with separate off-ramps but some shared on-ramps.  Exit 222 is for Martin Luther King, Jr. Boulevard (formerly US-421) and Exit 223 is for O. Henry Boulevard (still US-70/US-29/US-220 multiplexed, but US-70 won't be there much longer).  Oddly enough, these used to be exits on I-85 before I-40 was extended eastward.  I can't remember that far back, but I'm pretty sure that this was all a single exit when first constructed.

Not sure if this is what you're looking for, but the US-51 and WI-73 interchange off I-39/90 near Edgerton. WI-73 ends at the interchange while US-51 splits off from the Interstates to the south.

[Flint1979]

Does US-10 and M-25 ending at the same I-75 interchange but coming from opposite directions count?

[I-55]

In Indiana:

I-64 near New Albany has an exit for IN 62 and IN 64 that go opposite directions from the exit.

I-69 at Fort Wayne has an exit for US 30 one direction and IN 930 the other.

I-80/90 near Middlebury has an exit for US 131 NB and IN 13 SB.

I-80/94 at Hammond has an exit for US 41 NB and IN 152 SB.

I-69 Exit 234 serves IN-32 and IN-67

I-69 also has Exit 311A-B with US-27 and IN-3 going opposite directions

I-469 also has an exit for US-30 and IN-930

Indiana has a lot of these, too many for me to list them all.

MN 50/56 from US 52 in Hampton, MN
MN 101 and US 169 northbound from US 10 in Elk River, MN
MN 47 northbound and US 169 southbound from US 10 in Anoka, MN

Exit 54 on I-64 in South Charleston, West Virginia is for both US-60 (MacCorkle Avenue) and WV-601 (Jefferson Avenue).  Bonus points for Jefferson Avenue crossing under the middle of the cloverleaf offramp from the eastbound lanes and terminating on MacCorkle.

[Bitmapped]

In Mansfield, OH, work is currently underway to build a new ramp from US 30 eastbound that will serve both SR 13 and SR 545. These are parallel roads that are served by their own ramps right now. Westbound is keeping separate ramps for each road.

Exit 54 on I-64 in South Charleston, West Virginia is for both US-60 (MacCorkle Avenue) and WV-601 (Jefferson Avenue).  Bonus points for Jefferson Avenue crossing under the middle of the cloverleaf offramp from the eastbound lanes and terminating on MacCorkle.

Doesn't count. Eastbound, the exit is signed as US 60 To WV 601, a fairly rare case of WVDOH actually using the "To" label on signage. Westbound, WV 601 isn't signed.

Might Cranberry, which is signed for both I-79 and US 19 and has direct connections to both, qualify both in letter and spirit?

The Ohio Turnpike has interchanges with I-71 and US 42, and with I-77 and SR 21, that are similar to Cranberry.

MA-3:
----------------
Exit 32 (Old 13)

Listed highways:  MA-53, MA-123

The exit itself lands its ramps on MA-53, and MA-123 crosses MA-53 just north of the interchange.
-----------------
Exit 20 (Old 10)

Listed highways:  MA-53, MA-3A

The exit itself lands its ramps on MA-3A, and MA-53's southern terminus with MA-3A is just west of the interchange.

[Occidental Tourist]

There's exits in both directions off the 22 Freeway in Orange that are singular exits for both the 5 and 57 Freeways northbound.  Along the exit, they then split into the lanes for each freeway.  Does that count?

There's a similar situation for the 10 east in East Los Angeles.  There is one exit for the 5 south and the 60 east that later splits into lanes for each freeway.

There's an exit off the 5 in Coalinga, CA that is for Highway 33 in one direction and Highway 145 in the other.  Both highways are not marked on signs, however, with only 33 marked on the southbound exit and only 145 marked on the northbound exit.

Both directions of Highway 99 have an exit for Highways 108 and 132.

There's one exit off I-40 in Flagstaff for I-17 south and AZ 89A north.

There's are exits for Highways 89 and 267 off both directions of I-80 in Truckee, CA.

One example I just passed through today is Exit 150 on I-55 in Missouri:

https://www.google.com/maps/@37.9320948,-90.1163628,3a,75y,311.93h,88.48t/data=!3m6!1e1!3m4!1sMS_lGeYPS3kKnn8dAPGGMg!2e0!7i16384!8i8192

None of these three routes (MO 32, B, A) are multiplexed.

[Scott5114]

There's going to be a ton of these in Missouri. Lettered routes often terminate at each other at a primary-highway junction (whether a freeway or surface road).

[DandyDan]

In Clear Lake, IA, US 18 goes west and IA 122 goes east at I-35.

[Ned Weasel]

How about Exit 302 on the Will Rogers Turnpike?  https://goo.gl/maps/fmhqBcfYoK83N72JA .  US 59 crosses the freeway immediately, and US 60 crosses it several miles away.

[webny99]

Unless I missed something, I-390 northbound has a stretch of three of four in a row that qualify: Exit 11, Exit 12, Exit 13 does not qualify, and Exit 14.

(Exit 14 is a very interesting case because while technically you must use NY 15A to get to NY 252, that's only the case northbound, as there is both a crossing and a direct interchange between I-390 and NY 252 that just happens to be missing that one ramp).

Still Valley, NJ on EB I-78 Exit 3.

[tdindy88]

I-69 Exit 234 serves IN-32 and IN-67
Indiana has a lot of these, too many for me to list them all.

IN 32 crosses I-69 on both sides, it's a completely separate road from SR 67, which is just a county road on the other side. However, one exit to the south, Exit 226 would count as an example with SR 9 north of the exit and SR 109 south of the exit.

Can think of several in CT off the top of my head

I-84 Exit 5 Eastbound is for CT 37, CT 39, and CT 53.  CT 37 and CT 39 head on separate paths north of there, while CT 53 heads south. Westbound, CT 37 has its own exit (6), while 39 and 53 use Exit 5.

I-84 Exit 15 is for US 6 East and CT 67.  US 6 leaves I-84 and heads northeast, while CT 67 heads NW-SE (CTDOT logs CT 67 as an East-West route, but signs it North-South)

I-84 Exit 17 westbound is for CT 63 and CT 64.  The exit ramp becomes CT 64, and the junction with CT 63 is slightly west of there.  Eastbound does not mention CT 64, plus it exits directly onto CT 63. 

CT 8 Exit 38 is for US 6 West, CT 109, and CT 254.  US 6 joins/leaves CT 8 for a brief (1 exit) concurrency, CT 109's eastern terminus is at the exit, and the southern terminus of CT 254 is slightly north of the interchange.  Exit 39 Northbound is for US 6 East and CT 222 North (CT 222 has its own exit southbound).

I-95 Exit 86 is for CT 12 and CT 184.  The ramp becomes CT 184, while CT 12 can be accessed from a grade separated interchange about a half mile after exiting. 

I-95 Exit 92 is for CT 2 and CT 49.  The southern ramps use CT 2, and the northern ramps use CT 49.  CT 49's southern terminus is at CT 2 about 1/4 east of the interchange.

CT 15 Exit 59 is for CT 63 and CT 69.  CT 69's southern terminus is at CT 63 about 1/2 mile south of the interchange. 

CT 9 Exit 3 is for CT 153 and CT 154.  CT 153's northern terminus is at CT 154 just north of the interchange.

CT 8 Exit 44 is for US 202 and CT 4.  Both criss-cross, as US 202 heads SW-NE and CT 4 heads NW-SE.

I-95 Exit 53 for US 1, CT 142, and CT 146.  The latter 2 are coastal loops that have their termini at US 1 in close proximity (CT 142's eastern and CT 146's western).

I-87 at NY 2 and NY 7 just north of Albany (the "new" SPUI).

[1995hoo]

Exit 176 on the Beltway: VA-241 uses Telegraph Road between Route 236 (Duke Street) and the intersection/partial interchange with Kings Highway, and it then turns south on North Kings Highway, while Telegraph Road becomes Secondary Route 611 south of that point. Route 241 and Route 611 "meet," and the predominant thru movement on southbound 241 takes you onto southbound 611 (and vice versa from northbound 611 to northbound 241), but they are not concurrent.

[ozarkman417]

Might as well not include any in MO that involved the lettered routes, they are going to be everywhere. A couple that don't involve them include MO 158 and US 160 at US 67, as well as MO 376 and MO 76 on MO 76 (due to the structure of the routing, I don't know if that would count as an exit).

There seems to be a lot in Kentucky as well, many of them involving their four digit routes. In Owensburo, there is US 231 & KY 2155, and US 431 & 2831. In Bowling Green, there is I-165 and 9007. 

[wanderer2575]

I-696 at M-10 in Southfield MI (exit 8 eastbound, exit 10 westbound) is also signed for US-24, without TO banners.  In both directions, you actually exit to M-10 and then use M-10's exits to US-24.

I-96 at M-104 and M-231 in Nunica MI (exit 9) is signed for both routes, although they actually cross at a four-way intersection.  Eastbound on I-96, you exit to M-231 and then proceed south to cross M-104.  Westbound on I-96, you exit to M-104 and then proceed west to cross M-231.
https://goo.gl/maps/2DU2tCoRYkE3PCtV6

I-94 at M-96 and M-311 in Battle Creek MI is signed for both routes, although they cross south of the interchange.  (This one only qualifies eastbound because the westbound signs read "TO M-96.")
