Which two routes intersect the most number of times? In total, and within each state/province/equivalent?
For purposes of this discussion, a state route only applies in its individual state. For instance, MSR 16 (NC/VA/WV) intersects US 19 in both Tazewell, Va., and multiple times in West Virginia, but the Virginia intersection does not count in the total.
Discontinuous routes are separate routes. I-76 CO/NE is not the same as I-76 OH/PA/NJ.
The routes must intersect directly. For instance, Exit 28 on I-64 in West Virginia is signed for US 60, but the route actually intersected is not US 60, but a county route. It does not count in the total.
The beginning and end of a concurrency only counts for one intersection, not two. For instance, Exits 97 and 99 on I-75 in Kentucky only count as one intersection of I-75 and US 25, not two, since the routes are concurrent between the two exits.
I-64 and US 60 intersect in Kentucky seven times. That's more than US 25 and I-75, or US 31W and I-65.
If I had to guess the national winner, it would be I-95/US 1.
In Maryland:
I-70 and US 40 intersect four times.
MD 7 and US 40 intersect eight times, but it might not count because MD 7 is discontinuous.
In Virginia, US 11 crosses I-81 sixteen times and forms a concurrency with it once.
By the listed rules, I-70 and US 40 have nine intersections in Ohio. Ten if you include the interchange on the Indiana border where some ramps enter Ohio.
Louisiana has 5 interchanges between US 80 and I-20. Twice more where 80 crosses with no interchange.
There are 4 between US 90 and I-10.
Nationally there are:
11 Between 80/20
24 Between 90/10

I'm sure on the exact amount of times but CA 1 intersecting US 101 in California is the most common instance here.
I didn't check to see if all of the criteria were met, but a preliminary count indicates that I-75 meets US-41 14 times. Once in Florida, twice in Tennessee, and eleven times in Georgia.

If you count a (consistently) signed concurrency as a single intersecting point, the US 101/CA 1 combination has 7 intersections. Within CA, the only other combination that comes remotely close is I-5 and CA 33 with 4 intersecting points.
One factor not addressed in the OP: do the routes have to exchange directly or do grade-separated crossings with no access count?

My own count gives 12 times in Georgia, and that's not counting Exit 255 (where the northbound ramps go directly to US 41 but the southbound ramps don't, and the routes don't actually cross) or one other crossing without an interchange (and counting the overlap from Exit 22 to Exit 29 only once).
At any rate, surely nothing else in Georgia comes close to that.
I-91 and US 5 usually is brought up in this discussion.
I-96 (Michigan) has eight interchanges with former US-16 (Cascade Road and Grand River Avenue).

11 times including the southbound 301 crossing over and back over I-95 at Richmond.
23 i counted for US 1 not including its southern terminus in Miami and including 15E on the NJ Turnpike.
I-5 and OR 99 have 12, 14 if counting the old Wolf Creek turn off.
I-84 and US 30 have 20.

8 direct interchanges in Vermont alone. Regarding HighwayMan394's question, there are 11 additional grade separations between 91 and 5 in Vermont. And 2 additional "possibles" where the routes don't cross but there are direct ramps between the two.

One of the Midwest's leaders is likely I-74 and US 150. They cross each other 10 times, 7 of which are interchanges. That doesn't count the double-trumpet interchange in Peoria between the two where they don't cross.
I-80 and US 6 have 12 crossings/overlaps, 8 of which are interchanges.

There must be an intersection, where you can move from one road to the other. Grade-separated crossings with no access do not count.
On a national scale, I-80/US-6 has to be up there.
In WI, I-94 and US-12 cross seven times, though one of those crossings does not have an interchange.
MN doesn't have anything thrilling for this. Thinking it's I-35/MN 23 with a measly 3:
duplex from Exits 180-191
Exit 195
Exit 251B
First one I thought of was the aforementioned I-75/US 41 combination.
Utah doesn't have anything too exciting in this department. The best I can come up with is I-15 and US 89: coming from the south, US 89 crosses I-15 without an interchange just north of exit 279, then concurs with I-15 from exit 282 to 291. There's a weird bump at exit 312 that I'd say counts as an intersection, and then there's another concurrency from exit 317 to 324, which adds to a total of 6.
The best Indiana can do is I-65 and US 31, which have 6 interchanges.
I-65 has 4 interchanges with US 231.
I-91 and US 5 intersect 8 times in Massachusetts.
Illinois:
I-74 and US-150: These cross 10 times, some of which don't even have an interchange.
I-70 and US-40: These cross/meet 9 times. US-40 does use I-70 between some of the interchanges where they meet.

Those don't count.
Upon closer review, Kentucky's champion may be US 27 and KY 1247. They intersect 12 times in Pulaski and Lincoln counties. KY 1247 is the old alignment of US 27 and it parallels the newer route very closely between Somerset and Stanford.

US 1 lost one when I-295 took over at Oxford Valley and the interchange in Lawrence, NJ never had I-95 cross the US route.
US 13 and DE 1 meet several times, but no intersections or ramps between. I must admit this is a hard one, but keeps the mind going as so many routes do parallel but either don't meet formally nor cross like Florida. US 1 and I-95 meet only 6 times in over 350 miles of companionship.
US 90 and I-10 in almost the same manner cross only 3 times.
You get the idea. As many can be said in the whole US.
I mean, clearly it's I-81 and US-11. It was already mentioned that Virginia has 16. I'm counting at least 5 in PA, and New York has at least 10-12, depending on how we account for partial interchanges (less than 4 ramps).
Only problem is, no one has time to get a formal I-81/US 11 count for the entire country.
So, we might as well give some other routes the floor, even though they could never come close to being the actual winner. ;-)
I-65 and US 231 barely make this list with 4 crossings, but that includes three in a row (consecutive interchanges on I-65). Anyone have more where one of the highways is controlled-access?

It's actually 39 times. US 1 and I-95 intersect 3 times between Boston and the NH line. Once in Lynnfield, again at the Peabody/Danvers line, and again near the Danvers/Topsfield line.
Like someone else mentioned earlier I-10 and US 90 intersect with each other about 24 times, with 11 of those being in Texas.
I-20 and US 80 only intersect with each other once in Texas. It would've been a lot more if US 80 hadn't been truncated. Likewise with I-35 and US 81, I-45 and US 75, I-40 and US 66, and maybe I-10 and US 80 and 290.
I-35 (and 35E) and US 77 intersect about 10 times. 6 in Texas and 4 in Oklahoma.
I-30 and US 67 only intersect with each other 4 times, with 3 in Arkansas and just one concurrency in Texas. A lot less than I thought it'd be.
National winner is almost certainly I-95 and US 1. The number of interchanges between those two routes is absurd.
New York...let's address the possibilities:
I-87 / US 9 - 5 direct interchanges. Depending on how you count Exit 22 (reference route) and Exit 33 (short spur), could be as high as 7.
I-81 / US 11 - 9 direct interchanges, a few of which are partial
I-88 / NY 7 - Surprisingly, only 2 direct interchanges and 1 concurrency, but half of exits are signed for NY 7 and the connection is usually a short reference route.
I-90 / US 20 - Only 2 direct interchanges
I-190 / NY 266 - 5 direct interchanges, most of which are partial
I-390 / NY 15 - 4 direct interchanges
I-490 / NY 96 - 4 direct interchanges, 1 of which is partial
US 9W / NY 32 - 4, all concurrencies. This might be the most concurrencies between 2 routes in NY.
I-287 has 7 interchanges with US 202 in NJ (10 if you count one-way interchanges as separate). The true winner, though, is the GSP and US 9 (15 interchanges).

HB, I defer to you on this. The Binghamton-Syracuse segment of I-81/US 11 really needs to be taken case by case in this regard. There's tons of bits and pieces of interchanges but few full, clear-cut ones.
There's also the I-81/US 11 junction just north of the Scranton Airport, where there's weirdly direct ramps between the two routes without the routes actually crossing, so that's another situation we'll have to decide how to account for.

Which of the "indirect-ish" interchanges did you count?
Exits 8, 9, 10 in NY have at least 2 ramps connecting directly to US 11, so they count. Still tied with US 1 and I-95.
I count Exit 12, too. Still wavering on some of the others, like 2W.
Exit 6 could conceivably count twice: there is 2 crossings, and 2 ramps for each crossing.
Clarifications to my original criteria.
Partial interchanges do count.
Trumpet interchanges that connect directly to the intersecting route do count. The best example that comes immediately to mind is the US 522 Fort Littleton interchange with I-76/PA Turnpike. I believe I-81's interchange with US 11 on the south side of Harrisonburg would also qualify.
^ HB, how would you classify I-91 Exit 3 in Brattleboro, VT? I ask because there are a couple of driveways before one gets to the roundabout at US 5/VT 9 East.
I can't find anything in South Dakota more than SD 240 having both endpoints at I-90. Both major US routes that followed current Interstate routings (16 and 77) were decommissioned when the Interstates (90 and 29, respectively) were finished.

What's VTrans' internal designation for that connector? Is it considered part of the exit?
Meh..."Brattleboro State Highway" (unnumbered state highway)...

I'm sure on the exact amount of times but CA 1 intersecting US 101 in California is the most common instance here.
If you count a (consistently) signed concurrency as a single intersecting point, the US 101/CA 1 combination has 7 intersections. Within CA, the only other combination that comes remotely close is I-5 and CA 33 with 4 intersecting points.
The specific US 101/Route 1 examples I can think of:
Exit 60 in Oxnard (not well signed) - Rice Avenue
Exit 72 (Emma Wood State Beach)
Exit 78 (Emma Wood State Beach)
Exit 132 in Las Cruces
Exit 191B in Pismo Beach - Price Street/Business US 101
Exit 203A in San Luis Obispo
Exit 438 in San Francisco - Park Presidio Boulevard to 19th Avenue
Exit 445B north of Marin City
---
For comparison, here is Route 33 and I-5:
Exit 337 - Route 145/Coalinga
Exit 349
Exit 403A/B - Route 152 in Santa Nella (to Los Banos and Gilroy)
Exit 407 - Santa Nella
Exit 452 - north terminus in Vernalis

Does Rice Avenue technically count given it isn't "really under state maintenance" at present moment? Granted the difference is made up where CA 1 ends at US 101 in Leggett.

That one is tricky, because does this mean Oxnard Boulevard is still the Route 1/US 101 junction? Or does this mean that Route 1 essentially is a spur from wherever state maintenance ends near Santa Monica to the south city limits of Oxnard?
(Of course, some portions of relinquished Route 1 between Santa Monica and LAX are better signed than some state-maintained state routes here!)

Personally I'd count it if the Route was signed no matter who maintained it. Regarding Rice what we know for sure is that it is in the definition of 1 but isn't part of state maintenance. If 1 becomes signed on Rice no matter even if it's Ventura County signing it I would say at that point it is a legitimate part of the highway.
That brings up an interesting side thought regarding relinquishment in California. I know technically in most relinquishment agreements the term "no longer a state highway is applied." That said, many of those same relinquishment agreements require the local authority to maintain continuation signage (even though some places are better than others). Under that description I would still say that the State Highway exists by definition but simply isn't state maintained. In that sense something like CA 130 on Alum Rock in San Jose functionally exists even though all the signage has been removed and the city maintains it.

In my opinion, all of these edge cases count for the intent and purpose of the thread. Imagine if one route were a blue cord and the other were a red cord. The question is how many times do the cords cross. Who maintains what etc shouldn't really matter for this thought exercise.

Normally I would agree but the case of Rice and CA 1 is unique. Technically Rice Avenue never has been part of CA 1 nor signed as it. At present moment Rice Avenue is "the future" CA 1 which only will technically happen when it gets transferred to State Maintenance. I don't believe the former state highway on Oxnard Boulevard still has CA 1 shields still posted. So really until the state takes over Rice Avenue can it really be considered part of CA 1? Nonetheless US 101/CA 1 regardless intersect far more than any other pair of signed highways in California.
Edit: Here is what the Legislative description of CA 1 has to say regarding Oxnard:
"The relinquished former portions of Route 1 within the Cities of Dana Point, Newport Beach, Santa Monica, and Oxnard are not state highways and are not eligible for adoption under Section 81. For those relinquished former portions of Route 1, the Cities of Dana Point, Newport Beach, Santa Monica, and Oxnard shall maintain within their respective jurisdictions signs directing motorists to the continuation of Route 1. The City of Newport Beach shall ensure the continuity of traffic flow on the relinquished portions of Route 1 within its jurisdiction, including, but not limited to, any traffic signal progression."
So in that sense it would seem CA 1 still functionally exists in Oxnard Boulevard regardless of who maintains it.

Extremely unlikely.
