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.
https://goo.gl/maps/HFf5LjUc8cMgNog46
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 (https://goo.gl/maps/88yJDBcrvY4sQzWP6), Lehigh Valley (https://goo.gl/maps/Ufif1hct9k3cPAX3A), and Pocono (https://goo.gl/maps/XznqCi4E4LuitxMe7).
Might Cranberry (https://goo.gl/maps/GbgSgQzTgGma8WxB7), which is signed for both I-79 and US 19 (https://goo.gl/maps/Uk7hQHCqQjHdrXzH7) 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.
Does US-10 and M-25 ending at the same I-75 interchange but coming from opposite directions count?

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.

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.

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.
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.
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).
In Clear Lake, IA, US 18 goes west and IA 122 goes east at I-35.
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.
Unless I missed something, I-390 northbound has a stretch of three of four in a row that qualify: Exit 11 (https://www.google.com/maps/@42.9980906,-77.6726578,3a,75y,23.46h,90.56t/data=!3m6!1e1!3m4!1sbncqaF83pCbVwtlugxhLQw!2e0!7i16384!8i8192!5m1!1e1), Exit 12 (https://www.google.com/maps/@43.0469395,-77.6482485,3a,41.1y,29.53h,93.13t/data=!3m6!1e1!3m4!1s16zwVDD8ppLZASaYHCFaTA!2e0!7i16384!8i8192!5m1!1e1), Exit 13 does not qualify, and Exit 14 (https://www.google.com/maps/@43.0818128,-77.613061,3a,78.7y,55.48h,93.41t/data=!3m6!1e1!3m4!1sAx9pDc2WEVDPwOg-b4PgyA!2e0!7i16384!8i8192!5m1!1e1).
(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.

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).
Exit 176 on the Beltway (https://goo.gl/maps/zBoTuqoaQgZMGWvt6): 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.
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.
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.
https://goo.gl/maps/GTBT3vT7bH4mocr87
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.")
https://goo.gl/maps/k4iwSg6BouqG8Fcg9
Exit 181 of I-75 in Bowling Green, OH. OH-64 goes only west from the interchange, and OH-105 goes only east. Not sure if the official end/begin points of the two routes is on the bridge over 75, or at one set of ramps (actually roundabouts), or if each route ends short of 75 and the bridge is no-mans land.
Similar to the original example, US 62/US 45 at I-24 in Paducah.
And the KY 70/KY 90 Cave City exit on I-65. KY 70 crosses the interstate; KY 90 ends at KY 70 adjacent to the interchange. It's not posted as "To KY 90."
Formerly, the KY 205/KY 191 interchange (Exit 57) on the Mountain Parkway. Signed for both routes; the old EB exit ramp emptied onto KY 205 and the WB ramp onto KY 191. The routes were not concurrent through the interchange but began a concurrency just north.
With the four-laning of the Mountain Parkway, all ramps now empty onto a realigned KY 205, which is the through route, and it's signed "To KY 191" now.
Similarly, Exit 60 (westbound only) was for KY 134/KY 191. It emptied onto KY 134, which ended nearby at KY 191. A new exit is being built that will provide access to KY 191. Not sure how it will be signed. Probably KY 191/To KY 134.
2 in Nebraska off of I-80:
1. US 77 and L55-X on the NE edge of Lincoln. US 77 goes north, while L55-X goes south.
2. NE 11 goes north towards Wood River, while S-40D goes south towards Prosser.
One near me is TX-288 at FM 523 and CR 44 in Angleton. Strangely enough, both roads share the same southbound exit, but they get separate northbound exits, which is odd.
WI 147 and County Z off I-43 by Maribel WI.
I-75 Exit 50 Signed for M-5 (Grand River), it is the exit for Ford Field, Fox Theatre, Little Caeser arena, and Comerica Park. All are located at M-1 (Woodward).
If I'm reading this right, then I-290 Exit 6 (https://goo.gl/maps/8MXa3nH1ZyJeaTtU6) should qualify (though it should be noted that westbound traffic bound for NY 240 must use NY 324 and eastbound traffic bound for NY 324 must use NY 240).
Exit 91 on I-70 in Utah goes to SR 72 south and SR 10 north. The two really should be one route.
I-15 exit 222 used to be another - SR 28 went south, while SR 41 went north. In that case 28 was extended to absorb 41.
Exit 31 on I-4 in Lakeland, FL.
FL 539 goes south on Kathleen Road and County Road 35A goes north on Kathleen. Though FDOT does not sign CR 35A on the guide signs.
I-5 at WA 411 and WA 504 (https://goo.gl/maps/Tud2mscbL51QSYiM9) since both of those routes begin/end at the interchange.
There were some California examples brought up earlier, so adding a few more:
I-280 at I-880/Route 17, which was not originally an example of this until the redesignation of the San Jose-Oakland segment of what had been Route 17 (the Nimitz Freeway).
I-580 at I-980/Route 24, also similarly formerly a singular route with one number until the early 1980s.
First example I could think of was Exits 49A and B on I-78 east. (NJ-124 and NJ-82)

Well, of course, there's the "Oak Park" interchange on EB US-50 in Sacramento that signs CASR 99 south an CASR-51/Bus-80 North/East.
In and near Mountain View, CA, CASR-237, CASR-85, and US-101 each have exits signed for the other two, if I am not mistaken.
They keep trying to fix or eliminate the dual exit, but I-880, CASR-17, I-280, and CASR-85 all come together near a point and there are several exits from each signed for two or three of the others.
Of course, near San Jose, NB US-101 has a dual exit for I-280 and I-680, both of which start or end at US-101 and BOTH are signed as "North".
I-5 and CASR-14 may have a concurrency that disqualifies it, but there are several ramps that are signed for both.
I-210 and I-405 and I-5 come together in a jumbled mess near Santa Clarita, CA and there may be exits from I-5 signed for both (and maybe other combinations as well).
I am pretty sure that EB I-80 in Reno has signs for both SB I-580 and NB US-395 on the same exit.
If I remember right, I-405 has a dual exit for CASR-110 and for I-110, if that counts.
I would have to look them up, but, in and near Las Vegas, NVDot likes to use C/D ramps and might have a dozen ramps with the exits thereto signed for multiple numbered routes on many of them.

Since 51 has never been signed, it's essentially Business 80 East/99 South. Not sure if it completely counts as 99 is (silently) concurrent with 50 west of there (and until 2016-2017, so was Business 80).

I don't think any of the 210/5 and 405/5 ramps are connected to each other, at least from when I was last in that area. In fact, there is one exit on 5 between 210 and 405.

If I remember right, I-405 has a dual exit for CASR-110 and for I-110, if that counts.
Nope, that is actually...
US 101 in the Four-Level (where I-110 is fully signed for the southbound Harbor Freeway, with state route 110 only referring to the Arroyo Seco segment)
and
I-10 south of Staples Center (where the northbound Harbor Freeway is signed for state route 110, and southbound for I-110)
However, I don't know if either one counts as State Route 110 and I-110 are one single-numbered route from San Pedro to Pasadena. This is also why I'm not sure the transition of I-15 from Interstate to state route at I-8 in San Diego would qualify either.
On the other hand, I THINK the 405/110 junction involves some signage for Route 91 east.
On I-89, Exit 14 is US 2/VT 117 and Exit 20 is US 7/VT 207. 14 exits onto US 2 but VT 117 begins right near the exit, while 20 exits onto VT 207 but the road ends right near the exit. It's interesting because, if I remember correctly, VT between White River Junction and Montpelier is careful about signing Route X TO Route Y.
Former California example: I-10 at I-210/CA 57.
OR-217 Exit 2A serves both OR-8 and OR-10. OR-10 used to end at OR-8 in downtown Beaverton until 1982, when it was extended westward along OR-208 to end at OR-219.
https://goo.gl/maps/WMiWmkRxpdii6sdv6
I-5 Exit 271 serves OR-214 and OR-219, both of which end at the interchange.
https://goo.gl/maps/qCjZnk9qmo1xDPir9
The only Nevada examples I could think of:
*I-215 exit 1 is marked for I-515 north and I-11 south (both directions also carry both directions of US 93 & US 95). 515 becomes 11 at the 215 interchange.
*I-11 exit 23/I-515 exit 23 (formerly signed 62) is marked for I-215 west and SR 564 west. 215 ends at the interchange and can continue to where 564 begins.
*I-15 exit 33 northbound is currently marked for SR 160 and I-215/CR 215. This is more of a collector/distributor situation, where SR 160 is functionally a separate interchange from the 215...In the southbound direction, CR 215 west, I-215 east, and SR 160 are three separate exits.

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).
I was about to say, these are everywhere with lettered routes in MO.
The main one in AR that springs to mind is Exit 16 off of US 67 in Cabot (the "Heber Exit") where AR 5, AR 321 and AR 367 all spring from. The reality is that all 3 highways derive from an intersection about 100 feet east of the freeway interchange.
NC used to have one. I-40 at I-26/240 (Exit 46A-B eastbound) until they extended I-26 past the interchange. I guess technically since it's mostly future, it still counts
There's still I-40 at I-540 and Toll NC 540, if you count those as two routes.
Exit 189 on I-5 in Everett, WA has three terminating state routes: SR 99, SR 526, and SR 527.
Both ends of I-405 in WA also apply since the freeway continues on as SR 518 on the south end and SR 525 on the north end.
SH 5 and FM 902 at US 75 in Howe, TX.
A maybe involving secondary routes in Chesterfield County, VA: Exit 58 on I-95 (SR 620 and 746), though the exit is split into B&A on the southbound side
I'll try Colorado...
I-25:
Exit 50 in Walsenburg: CO-10 E/US 160 W (Only signed for CO 10 because US 160 is signed on either end of the I-25 BL)
Exit 101 in Pueblo: CO-47 E/US 50 W
Exit 184 in Castle Rock: CO-86 E/US 85 N
Exit 201 in Denver: CO-30 E/US 285 S
Exit 216B in Denver: I-76 W/CO-224
I-70:
Exit 171 near Avon: US 6 E/US 24 W
Exit 205 in Silverthorne: CO-9 N/US 6 E
Exit 316 in Byers: US 36 E/(unsigned from I-70) CO-36 W
US 50 in Pueblo has an interchange with CO-47 W & CO-96 E (different interchange than the I-25 one listed above)
Bonus:
Near Empower Field in Denver, US 287 exits itself (SB 287 exits from SB Federal Blvd to EB Colfax Ave & NB 287 exits from WB Colfax Ave to NB Federal Blvd) but also meets CO-88 south of the interchange (on Federal) and US 40 & I-70 BL continue as a multiplex west and east (also multiplexed with US 287) of the interchange.
Some more California examples:
US 101 at I-280/I-680 in San Jose
US 101 southbound in the East Los Angeles interchange, where the options at the end are Route 60 and I-5. Though that depends if you consider I-5 as the last exit of US 101, or rather factor in that it is the seamless continuation of the southbound Santa Ana Freeway (which used to be 5/101 together in the 1960s).
Similar to the 101 example, Route 170's now-south terminus at US 101/Route 134 at the Hollywood Split, though this depends on if 170 feeding into 101 is seen more as the direct continuation of the Hollywood Freeway. (And like the past 5/101 concurrency, there used to be an unsigned 101/170 multiplex between 134 and Highland Avenue until about 4-5 years ago.)
Someone earlier mentioned 210/57 at the Kellogg Interchange with I-10; would 10 with 57/71 still count for this?
Depends on how you look at it but I-10 for US 319 and FL 61 near Tallahassee can be if you take in the fact that the US 319 and SR 61 concurrency is not signed.
Florida's Turnpike Exit 289 (SB) and Exit 285 (NB) are for US 27/FL 19. The three routes all cross over each other. https://goo.gl/maps/Tok9Uqi6WULg9btR7
This one applies to CA 99 in Merced -- but SB only -- at the V street exit, the BGS is signed for both CA 59 and CA 140; 59 heads northeast from the interchange, while 140 heads southwest for only a few yards before turning west toward Gustine. Both do multiplex with each other and CA 99 past the interchange, with 59 departing the "triplex" (neither have reassurance shields) south prior to 140's eastward departure south of town. NB the situation is similar at the V Street exit, but 59 & 140 are already multiplexed with CA 99.
Missouri have so many of these examples because of how letter routes work; they normally terminate at a junction with a higher-tier route. Here's the St. Louis area examples I can think of off the top of my head:
- I-64 Exit 4 - MO 364/MO N
- I-270 Exit 16 - MO 364/MO D
- I-70 Exit 217 - MO K/MO M
- I-270 Exit 5 - I-44/MO 366
- I-55 Exit 196 - I-270/I-255
- I-64 EB Exit 9 - MO K/MO 94 (It's 2 seperate exits in the WB direction, with MO K as Exit 9 and MO 94 as Exit 10)
- MO 21 - MO MM/MO M
I wonder if this would qualify:
I-270 NB exit for MD 117 and MD 124.

This first sign guides traffic from the main freeway lines to the local lanes for exit. Then on the local lanes, you see this:
https://www.google.com/maps/@39.1409023,-77.2123945,3a,75y,352.9h,89.77t/data=!3m6!1e1!3m4!1sXETVOjuReFq9rChaIYz0pw!2e0!7i16384!8i8192
So 117 and 124 intersect a little to the west of I-270. Taking the exit for 117 leads you to 124 south, but it is more direct to take the second exit for 124 south.
I guess this really deserves a TO, but it isn't signed that way.
I-81, Exit 1: US 11/NY 7 (Kirkwood/Conklin interchange). An access road leading west from the interchange provides the connections to both US 11 and NY 7.

Similar in vein, I-81, Exit 12: US 11/NY 41/NY 281 (Homer interchange). Another access road leading west from the interchange providing connections to US 11/NY 41 and NY 281.

Along the same lines as the OH 64/OH 105 interchange in Bowling Green, OH:
NY Thruway, Exit 39: I-690/NY 690
I-81, Exit 29: I-481/NY 481
- even though both are physically the same highway
A former CA example, also on CA 99, was in Bakersfield, where CA 58 went west and CA 178 went east. That one was a victim of Caltrans' recurring "relinquishment madness" -- although probably prompted by Bakersfield's desire to remove through traffic from the downtown couplet. AFAIK, the CA 58 reference remains, but isn't long for the world, just waiting for the Westside Parkway connection to be completed (much of the old CA 58 alignment has itself since been relinquished).
