One exit for two or more routes that are not multiplexed

[TheStranger]

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.

https://www.google.com/maps/@39.1368841,-77.210506,3a,75y,348.04h,84.24t/data=!3m6!1e1!3m4!1sjhFnSLaGlJqFBu1XZ9gaiw!2e0!7i13312!8i6656

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).
