Same exit with different numbers depending on the direction

I noticed something interesting, at both points where I-70 crosses I-465, the exit has 2 different numbers depending on the direction you are traveling.  On the west side, if you are going EB its exit 69, if you are going WB it's exit 73.  On the east side of town if you are traveling EB it's exit 89, if you are traveling WB it's exit 90.  Any other locations where this happens?

Interesting thread, thanks for posting it! Most of these situations (and both of these specifically) occur when ramps are moved from their original locations due to a rebuild of the interchange.

Of particular note is the 4-mile distance between I-70's IN Exit 69 and its actual crossing of I-465 near reference post 73. Discounting I-865 (which a vocal minority here consider to be just two very long ramps), it is definitely the longest freeway ramp in Indiana and likely one of the longest in the entire country. It came about in the mid-2000s with the rebuild/relocation of I-70 to serve the (then under construction) relocated passenger terminal at Indianapolis International Airport (IND), as well as to allow for a future 4th runway (3rd parallel one) at that adjacent facility. Eastbound drivers definitely don't want to miss that exit, as their only option to rectify that mistake (short of any highly illegal & dangerous movements) is a quite lengthy (12 mile) detour - remaining on I-70 for another 8 miles to double-back at the Holt Road exit (#77). They cannot easily double-back at the only intermediate interchange between those points, the Sam Jones Expressway (exit #75), since it is only a partial interchange. That is unless they take its only EB exit (to EB Sam Jones) and then attempt a U-turn (which may not be legal) at Stout Field East Drive.

That's what happened with the I-35/75th St interchange in Overland Park, KS. This was previously Exit 227 in both directions.  Between 87th St Pkwy and 75th St, NB US-69 (Overland Pkwy) merges into I-35. In 2012, the Overland Pkwy was expanded from 2 lanes per direction to 3. However, there was not adequate space to merge three lanes of 69 into the three lanes of I-35 before the existing ramp to 75th Street. (The current overpass only allows for 3 lanes to go through. The on-ramp from 75th becomes a 4th lane on the other side.) To accommodate this the exit was moved 2 miles back as an off-shoot of the ramp to 87th St Pkwy (225A) and was renumbered to 225C. (Exit 225B is for US-69 and a SB only exit.) The ramp to 75th St passes underneath 87th, the northbound on-ramp from 87th, and US-69 before running parallel to I-35 for well over a mile. The SB exit is still 227.

In Cincinnati, I-71 exit to OH 562 (aka Norwood Lateral) is exit 8B Northbound, but Exit 7 Southbound.  The two ramps start in almost the exact same mile mark on I-71.  The northbound exit falls in between exits to southbound and northbound Ridge Ave (Exits 8A and 8C).  Southbound the exit is south of the exit to Ridge Ave (which is Exit 8).
