Thought of this when revisiting my "Exit number ranges in downtowns" thread and a few GSV visits, and found out that there's at least 4 freeway-freeway junctions in the US with the exit number 53 on one side:
- I-90/94 and I-55 in IL, exit 53 on I-94
- I-70 and I-270 in MD, exit 53 on I-70
- I-75 and I-94 in MI, exit 53 on I-75
- I-465 and I-65 in IN, exit 53 on I-465
Any other freeway-freeway interchanges that's exit 53 for one of the highways, or another exit number used in multiple freeway-freeway interchanges?

21 is another common one I've noticed:
- I-80/90 and I-80/94 in IN, exit 21 on I-90
- I-70 and I-79 (south) in PA, exit 21 on I-70
- I-595/US 50/US 301 and I-97 in MD, exit 21 on US 50
- I-78 and I-287 in NJ, exit 21 on I-287

I haven't seen a 21 myself, but a lot of 20s. There's four 20s in the St Louis area to start off, and most likely a lot more in the rest of the country:
- I-270 and I-70, exit 20 on I-270
- MO 364 and I-270, exit 20 on MO 364
- I-255 and I-64, exit 20 on I-255
- I-55 and I-70/270, exit 20 on I-55
EDIT: Some exit 20s not in St Louis:
- I-465 and I-65 northern interchange, exit 20 on I-465
- I-480 and I-77 in OH, exit 20 on I-480
- I-355 and I-88 in IL, exit 20 on I-355
When Florida had sequential exit numbers, Exit 53 was for I-4 near Mango, FL on I-75. Now its Exit 261 of course, but it was in the 20th Century a number 53 exit. :sombrero:
One end of a 3di should normally be numbered 0 or 1, so those numbers probably have a lot of freeway-freeway interchanges.
In Georgia, when exit numbers were sequential, the I-20 & I-285 interchange east of Atlanta (in DeKalb Co) was exit 35 for both routes. The I-85 & I-285 interchange north of Atlanta (in DeKalb Co) was exit 35 for I-85.

2di's too, for that matter...I-78 & I-81 both come to mind at their west/south ends.
But point taken regardless, 1 is probably the low-hanging fruit for this thread :-P
^ The southern terminus of I-65 is Exit 0.
From the land of sequential numbering, NY Thruway (I-90) exit 53 is for I-190.
The US-421 / SH-74 (future I-74) interchange in Greensboro is Exit 53 on SH-74 / I-74.
The I-295 / I-64 western interchange in Richmond is Exit 53 on I-295.
The I-66 / VA-28 interchange in Northern Virginia is Exit 53 on I-66.
The I-30 / US-80 interchange east of Dallas is Exit 53 on I-30.
If US 46 was a full freeway, NJ Exit 53 on I-80 would be in the club.

It's is a JerseyFreeway though but don't count as it's full freeway as per OP. Only in NJ they can seal a median of crossovers and build interchanges at crossroads, but leave the rest such as businesses on the road to improve traffic. Though PA with PA 12 in Reading has Jersey ideas along Warren Street and part of Massachusetts on US 1, it's a jersey thing really.
Btw not criticizing it, but saying that other states should do that as well.

From the land of sequential numbering ...
Exit 20 on I-390 is I-490
Exit 21 on I-490 is NY/I-590
Exit 21A on I-87 is the Thruway Berkshire Connector
Exit 21 on I-190 is the Niagara Scenic Parkway (northbound exit/southbound entrance only; commercial vehicles prohibited)
Exit 21A on I-190 is the LaSalle Expressway
Exit 21 on I-86, currently for US 219, is an interesting case. A new freeway has been proposed for the US 219 corridor, which is likely a very long-term proposition at this point, but it's also worth noting that Exit 22 was skipped (possibly with this in mind?) so it seems likely that 22 would be used for the new interchange with US 219, rather than 21A or B. (It's also possible that the entirety of I-86 could have converted to mile-based numbers by the time this ever happens, so this could be moot by then.)
