Most of Arizona's rural Interstates are open to bicycles, with the exception of I-10 between Phoenix and Tucson, where cyclists must go via Florence instead using SR 87 (or Hunt Highway), SR 79, and SR 77.

I-17 has pretty specific signage when bikes are allowed to enter and when they need to exit. The climb from Black Canyon City north to AZ 69 is a pretty notable example. Why do I get the feeling that Bike Hazard guy is going to pop up now?

True, but I think the OP was seeking more where it's legal to tool down the breakdown lane of the interstate.

ADOT has a formal written policy see:
ADOT Traffic Engineering Policies, Guidelines, and Procedures Section 1000 — Miscellaneous, 1030 CONTROLLED-ACCESS HIGHWAYS AS BIKEWAYS
"bicycles are permitted by law to operate on all State highways, including controlled-access highways, except where excluded by administrative regulation and the posting of signs to give notice of a prohibition" . Which then goes on to list specifically where the prohibitions are, what are generally speaking the urbanized areas. For example the restriction on I-10 is from MP 120.22 (Verrado Way) to MP 270.59 (Kolb Road) – that is the entire Metro Phoenix through Metro Tucson region.
Besides ADOT ("the director" ), I am not aware of any circumstance where any other authority has prohibited bicyclists in Arizona.

I-84, I-15 to Exit 87 (US-89) near Ogden
I-215, full route
SR-154, full route
If you asked me, I wouldn't allow bikes on any urban freeway or expressway, since there are many surface road alternates. I also wouldn't allow bikes on a rural freeway where there's a parallel surface road in decent condition nearby, such as an old alignment of a US Highway that was replaced by the interstate.
There’s really no reason bicycles should ever be on SR-67 or the north half of SR-85, because there are parallel bike trails next to those routes.
EDIT: as Kniwt pointed out, the no-bike zone in St. George has been extended in both directions.
They will be on the New 74 bridge in the Quad Cities just like 72 but in general they are banned along with pedestrians on most Illinois interstates.

This was very recently changed when UDOT posted new signs extending the restriction area from Exit 2 (SR 7) to Exit 16 (SR 9), even if the website hasn't been updated yet. It's not really a big deal since there's practically a frontage road, pathway, or nearby alternate the entire way.

True, but speaking as an experienced cyclist who's been on a bunch of freeways, mostly in the West (including MP 0-8 and 27-29 on Arizona I-15), I would
never attempt I-15 through the Virgin River Gorge in either direction unless I had a slow-moving support vehicle directly behind me to protect me (which, of course, isn't allowed).
Most of the shoulder is narrow to nonexistent, the shoulder surface has deteriorated to practically gravel, and there are several substandard crossings of the Virgin River with
no shoulder at all. (The recently rebuilt Bridge 6 has a nice shoulder, but that's about it.) Oh, and everyone drives through the gorge like a freakin' maniac. :)
Strava reports that at least a few riders have tried it, and I believe I've seen maybe two over the past three years -- and they often appear to be international long-distance tourists who have no idea what they're getting into.
ADOT no doubt keeps I-15 bike-legal because they "have" to; the only alternative is Old US 91 over Utah Hill, which is longer and involves a climb of nearly 3,000 feet northbound (and 1,700 feet southbound).

...sort of. With the bridge reconstruction, they're going to add in a pedestrian/bicycle path on the Illinois-bound side, but it will be separated from vehicular traffic by at least a barrier.
I'm pretty sure bicycles are banned on all freeways in Iowa as well.

I'd be more worried about the debris and other crud in the breakdown lane than traffic. Having ridden on a few super-twos in New Hampshire, the closest thing I have to an interstate that I can legally ride on, I've never been too concerned about it. I have my head on a swivel at the on/off ramps, but other than that it may likely be safer than many regular roads.

I'd rather ride my bike on an interstate with wide shoulders and minimal driveways/cross streets, even with 70+ MPH traffic, than a 2 lane road with narrow or no shoulders, more driveways and cross streets, and 50+ MPH traffic. Most interstates (excluding some urban ones where you probably aren't allowed, and some older bridges) have quite wide shoulders. State or US routes, total crapshoot.
At least if safety is the only consideration. In reality, I'd probably stick to side highways just for it being more scenic and interesting (even though it may be more dangerous in many cases).
Remember that the standards of the I-system make for exceedingly safe bicycling on lower traffic routes, such as many of them in the west - looooong sight lines and wide paved right shoulders give plenty of room and visibility.

Not sure how dangerous it would be with the typical 10 foot paved right shoulders, but unless the shoulder is kept well-swept there would be gravel and other debris on the shoulder. It would also be a very noisy environment, with the tire noise and engine noise and wind noise of cars and trucks at Interstate speed, and there would be blasts of wind from trucks.
I have not biked an Interstate, but I have biked the new VA-147 Huguenot Bridge over the James River in Richmond.
I use the bridge several times per week and the average number of pedestrians and bicyclists on the bridge at any one time is probably 1.0 or less. I walked the new bridge once and biked it once, it has a great view of the river but it is very noisy with all the high speed traffic (45 mph limit), so that is likely why even with UR nearby very few pedestrians and bicyclists use the bridge. The shoulders are 10 feet wide and the sidewalks are 5 feet wide, so there is plenty of space for pedestrians and bicyclists. I felt safe enough but it was a very noisy experience.
That is 45 mph and very few large trucks. Now imagine 70 mph and lots of large trucks!

Most rural Interstates in the west now carry 20,000 AADT or more, traffic has steadily increased over the years. Some segments carry a lot less, such as the northernmost reaches of I-15 and I-29, but the east-west routes in particular carry heavy car and truck traffic.
Safe but noisy (see my other post).

We have problems on the divided highway of Loop 360. Bikers think it's this great biking highway and there is really too much traffic for it (divided highway). If underpasses were put under exit and entrance ramps (or bikes were required to also exit) I would think most rural freeways with wide shoulders would be okay for bikes.

I opted to test the first part of your theory. Below is a map showing estimated 2017 AADT volumes for the Interstate system. Base data year is 2012 (most recent year I could find at a national level). An 8.4% growth factor was applied based on national VMT trends between 2012-2017.

While each east-west Interstate across the Rockies and the Great Plains has some 20K+ AADT segments, each has lengthy segments that are below 20K AADT. Each also has at least one segment that drops below 10K AADT, with I-40 being the only one that
doesn't consistently drop below 10K for lengthy segments. The same also applies to I-15, I-25, and I-29. I-5, the Arizona north-south Interstates, and I-35 are busier, but even I-35 has several segments north of OKC that are below 20K AADT as does I-5 between Redding, CA and Medford, OR.

Who compiled that data? I can't believe that those segments of I-80 and I-70 are less than 10,000 AADT.
That is the volume on VA I-64 across North Mountain in Rockbridge County, extremely low by eastern standards.
who here is an avid cyclist? I cycle regularly, when I do, i try to keep it off road as much as possible. Too many distracted drivers! There are a lot of multi-use paths where I live, so I ride on those.
I am.
When I was in Austin, Texas for holiday/work a few years back, I had to bike on the shoulders of several freeways - which were marked for cyclists and were popular touring routes for many others. It was necessary in many cases because getting to the hills would have otherwise been impossible or downright awful. It felt completely safe, separated by traffic, and the shoulders were generally very clean.
I've also biked on other freeways/expressways, such as Corridor H/US 48 in eastern West Virginia.
I find it easier to bike on those types of roads for long distance travels.
i think the biggest problem, at least in my experience, is that the shoulders are full of junk, making it not a good place to ride.

Especially west of the US 6 split at Green River, through the San Rafael Swell (the longest interstate segment without services—110 miles). East of that junction you can get some areas of higher traffic, especially during tourist season (though still less than 10,000 AADT).

Because, depending on the specifics of the roadway in question (exit spacing, ramp volumes, number of trucks, and several other variables), one typically doesn't start seeing heavy congestion on such roadways until you're well north of 40K daily volume (in some cases north of 60K).
I used 20K as the threshold to test Scott's hypothesis that most western Interstates had that volume level or higher.

That is surprising for a transcontinental route that connects the cities that I-80 directly serves, including Sacramento and the S.F. Bay area just to the west of there.
That would demontrate the silliness of the proposals for an Interstate highway connecting Carson City to Las Vegas, which would undoubably have far lower traffic volumes.

I bicycled Interstate 90 from North Bend to Snoqualmie Pass and back, in 1994, when bike racks went on Metro buses and before I had a car. Also, the parallel Iron Horse Trail was missing a trestle, so I had to detour from it anyway. I never had to drive past an exit ramp. I took each exit to take available Forest Service roads and other roads. One time when taking an exit, I saw a startled wolf walk away from where he was right by the Jersey barrier by the exit, then stop and look back. I had too much momentum to stop right there myself. It was exhausting gaining that much elevation at once. In the future, once I got a car, I would do the loop in reverse: park at Rattlesnake Lake and take the trail up to the tunnel. Then go up to Snoqualmie Pass and down via forest roads and one segment of I-90. It's much more fun to bike downhill.
You're allowed to bicycle most non-urban sections of Interstate in Washington, the non-black and red segments here (https://www.wsdot.wa.gov/travel/commute-choices/bike/state-map).

This September 2017 letter (pdf) to IDOT from advocacy group Ride Illinois suggests that the official answer is no, but ...
QuoteAt present, I-180 is certainly overbuilt as an interstate, for only 2500 ADT. Despite bikes being prohibited, Strava's heat map (labs.strava.com/heatmap) of bicycle trips by users of that app confirms at least some cyclist usage, not a surprise given the low traffic, four lanes, and lack of alternatives.

I'm planning a bit of a bicycle trip I may or may not take next year, and I'm curious, is I-180 over the Illinois river open to bicycles?
This September 2017 letter (pdf) to IDOT from advocacy group Ride Illinois suggests that the official answer is no, but ...
QuoteAt present, I-180 is certainly overbuilt as an interstate, for only 2500 ADT. Despite bikes being prohibited, Strava's heat map (labs.strava.com/heatmap) of bicycle trips by users of that app confirms at least some cyclist usage, not a surprise given the low traffic, four lanes, and lack of alternatives.

Kind of what I thought. IMHO, that's the one place in Illinois I can see bicycles on an interstate justified.
^ What about in East Hannibal? IIRC, bicycles are allowed in the shoulder of the Mark Twain Bridge (I-72 over the Mississippi) between the MO 79 and IL 106 interchanges.

Good point.

Quote from: BeltwayWho compiled that data? I can't believe that those segments of I-80 and I-70 are less than 10,000 AADT.
FHWA, via the respective (and required) state DOT data submittals.
Having been on it, I can definitely believe I-70 being less than 10K through Utah.
Especially west of the US 6 split at Green River, through the San Rafael Swell (the longest interstate segment without services–110 miles). East of that junction you can get some areas of higher traffic, especially during tourist season (though still less than 10,000 AADT).
I was on that section of I-70 (actually all sections) last week and was surprised to see an orange-background sign with a bicycle pictograph and "All bicycles must exit" wording due to upcoming bridge work. Also saw a bicyclist pedaling along the shoulder near one of the peaks-that could have been in Colorado.
