For Massachusetts, it's 65 on MA 24, MA 140, US 44 freeway section, US 3, MA 25, and MA 146.

You can do other states as well as we don't have a forum member from every state.

70 MPH on CA 99 south of Merced.  There was also a 70 segment on US 101 south of King City which was downgraded recently to 65 MPH.

In Alabama, the highest non-Interstate speed limits will always be 65 MPH, and only on dual carriageways. Two-lane roads won't be any higher than 55.
All of the neighboring states (TN, FL, GA and MS) are the same way.
It's all fun & games until someone summons Cthulhu and brings about the end of the world.

I also collect traffic lights, road signs, fans, and railroad crossing equipment.

Unrelated, but does California underpost speed limits? I tried to find the speed limit on CA 58 and CA 14 on GSV and couldn't find any signs. Had troubles on 101 as well.

I think Florida has 60 on a few 2 lane roads. Was US 78 70 before it become I-22?

Caltrans is sparse on signing speed limits.  That said, I think 14 is 70 MPH north of Palmdale/Lancaster in places?  58 is on the freeway segment east of California City towards Boron.

Amusingly there several mountain state highways with almost no speed limit signage.  CA 245 north of Woodlake and CA 198 west of Coalinga spring to mind off the top of my head.  You get one speed limit sign and that's it.  You're pretty much on your own to decide if 55 MPH is something you can handle.

Minnesota caps non-Interstates at 65, which is common on outstate expressways and a few fringe suburban freeways outside 494/694.

In Wisconsin, 70 is allowed on any fully access-controlled freeway regardless of the Interstate status.

It's CalTrans's practice to sign speed limits on freeways only after on ramps and otherwise when it changes. On roads without controlled access, they may do it a little more frequently, or often not bother. A lot of Sacramento county's outlying roads didn't have ANY posted speed limits and defaulted to the state default maximum.

Michigan, 75 mph on northern sections of freeway US routes. I don't think there are any 75's on M- freeways, so it would be 70 for those.

jeffandnicole

Both NJ & DE is 65 mph, which is the max speed limit on any roadway in either state.

tman

Nebraska expressways and non-Interstate freeways are posted at 70mph outside of urban areas, while most two-lanes are posted at 65.

We don't have too much for non-Interstate freeway - one example is US 75 in Omaha (there are two portions north and south of the I-480 concurrency) which is posted at 60mph, until the Sarpy county line southbound when it jumps to 70mph. The West Dodge Road freeway is another.

US 95 in the entirety of its length besides the towns has a speed limit of 70 mph in Oregon. Don't know why this is, considering both US 97 and US 395 do not go higher than 65 mph in terms of their speed limits.

It was intended to match the speed limit on the Nevada section of the ION Highway.  There really isn't much of a reason not to go at least 70 MPH out on the ION.

Yeah, besides in urban areas of course. I've driven on a lot of the ION, great road. One of the main streets of the Mountain West.

Virginia has a single stretch of non-Interstate 70-mph speed limit on a segment of US-29, the Lynchburg–Madison Heights bypass. Other than that, no non-Interstate in Virginia is posted higher than 65.

Hghway speeds are 70 mph at multiple locations throughout the DFW Metroplex, including on Central Freeway. Realistically speaking, you'll be lucky to hit 70 on the close-in highways other than late-night hours. You won't see 75 until you get outside of the Home Counties because of EPA anti-smog attainment regulations.

Nevada:

Many two-lane highways including much of US 95 as mentioned above are posted at 70 mph.

But, the highest posted limit on a non-interstate is 75 mph on the four-lane divided portion of US 95 between I-11 at Boulder City and SR 163.  Beware the drop from 75 mph to 25 mph as you pass through Searchlight, though.

NY: 65 on US 219, NY 531, NY 481, NY 49, NY 7, and the Berkshire Spur.  Also NY 17, but since that's theoretically supposed to become I-86 eventually, does that really count?

VT: 65 on US 4

NH: 65 on NH 101 and the Everett

Illinois:  65 on multiple rural expressways and non-interstate freeways.  IIRC a non-interstate tollway could be posted at 70 (the current state maximum for interstates), but the only non-interstate tollway at currently in existence is IL 390 in Chicagoland.  Otherwise Illinois statutes caps non-interstates at 65.

Iowa:  65 on multiple rural freeways and expressways (a state that requires an interstate shield for a route to be posted at the state maximum of 70).

Missouri:  70 for parts of MO 7 between I-49 and Clinton (expressway), parts of US 54, parts of US 63, and possible a couple other routes.

Nebraska:  70 for non-interstates and rural expressways such as Highway 2 around Nebraska City and some of the US 75 freeway heading south from Omaha.  IIRC another state that requires an interstate shield for a road to be posted at the state maximum (75).

You would think that Iowa would allow much of US 20 to be 70

65 mph for Indiana (SR 641, US 31- Kokomo Bypass & Plymouth to South Bend, St. Joseph Valley Parkway- US 20/31, and US 24- east of Fort Wayne)

Regarding Oregon, US 95 is 70 MPH because that was written into law. The story with 70 MPH limits in Oregon is that ODOT refused to raise anything despite the leg allowing 70, so the leg wrote into law that I-84 and US 95 must be 70. This also makes Oregon one of the few states where the highest undivided road speed limit is the highest limit found in the state. Hawaii and I think Alaska are the others.

California is relatively stingy with 70 MPH in general. That is, it needs to be rural, not mountainous, and built to modern freeway standards. Because of this, few non-Interstates qualify for consideration, and even I-80 doesn't qualify anywhere along its route. US 395 probably would if it were built to freeway standards, but a full freeway is unnecessary.

Nevada, yes, is 75, and that is the only expressway-grade road in the state with a speed limit over 70. 95 north of Vegas is the only other expressway-grade road in Nevada with a limit over 65. NV generally doesn't like posting over 65 on a surface road if there are people living anywhere nearby, so despite the state being infamous for its 70 MPH speed limits, the limit often drops to 65 or below the second you near farms or homes. Even the 80 MPH limits are relatively rare and restricted to a few straight/flat sections of 80.
