Highest speed limit in your county?

[stevashe]

Pierce County, WA (directly south of Seattle).

60 mph; all the freeways. No rural freeways that could take advantage of 70 or 75, and the rural state highways either top out at 55, maybe one spot of 60 that I can't think of.

I believe you are correct.

For King County, it's I-90 from east of Issaquah to Exit 47 with 70 mph.

I'm thinking Pierce County might be the only one with an interstate that does not have a 70 section? Snohomish County is in the clear, as is Thurston and Clark.

Yup. Franklin County would be another candidate, but surprisingly I-182 stays 70 through Richland and well into Pasco before dropping to 60 just before the US 395 interchange.

I agree that's surprising for Washington. They're often pretty quick to drop the speed limit in suburban areas. Even if that weren't the case though (I could definitely see it lowering eventually as Pasco continues to grow, though with the design of the freeway it's perfectly fine at 70), US-395 is 70 MPH north of Pasco, which is a lot of mileage.

Jake was only asking about interstates, though.

[gonealookin]

Douglas County and Carson City are the only two county/county equivalents in Nevada that don't have at least a 70 MPH zone.  The best we can manage in Douglas County is 65 MPH on US 395 through the Carson Valley, and Carson City's highest is also 65 MPH on I-580/US 395.  Storey County's tiny section of I-80 is posted at 70 MPH.  NDOT speed limit map for major highways here.

[deathtopumpkins]

In Massachusetts, I think that every county has 65 except for Suffolk (55), Barnstable (55, unless MA 25 makes it into the county), and the two island counties.

MA 25 does indeed make it into Barnstable county, and is posted 65.

No it doesn't... does it? I think it ends on the west side of the canal.

The county line is not the canal. MA 25 is on the west side of the canal, but it does cross the county line.

The town of Bourne extends past the canal right?

Depends on how you interpret it. "Pierce County might be the only one with an interstate that does not have a 70 section", I interpreted that as "a county with an interstate, with a 70 MPH limit in the county", not "a county with an interstate, with 70 MPH on that interstate". Moot point either way though.

Was US-95 south of Boulder City lowered from 75 to 65, or is the map wrong? See GSV here, just over a year old https://www.google.com/maps/@35.9184935,-114.9181082,3a,75y,209.33h,74.03t/data=!3m7!1e1!3m5!1s0e3TxVA8auJV0cWs0x9AtA!2e0!5s20190301T000000!7i16384!8i8192

I'd really hope it's not lowered, seems like a reasonable limit considering the terrain and road design. 75 MPH on a non-freeway is pretty unprecedented outside of Texas, but it seems reasonable here. 65 would be ridiculous, if they lower it, it should be to 70 like most of the other US highways in the state.

Whoops.  I skimmed over the map before posting the link and it appeared accurate including the fairly recent increase from 75 to 80 on I-80 between Elko and Wells.  Looking through NDOT news releases for the last couple years I don't see any change on that segment of US 95 and while I haven't driven that road for maybe two or three years I'm pretty sure the map is wrong.

Waze still shows 75 mph. Figured if it had been lowered, it would've been updated by now.

IMO, I-11 ought to at least be posted at 70 or 75 mph south of the Boulder City Pkwy, reducing to 65 mph near Hoover Dam and the mountainous areas.

[D-Dey65]

For Hernando County, FL, it's 70 MPH on most of the Suncoast Parkway except when it approaches the Oak Hammock Toll Plaza, and all of I-75.

I agree with you about I-11's speed limit.

I have a question. Google, Apple, and Yahoo all seem to know the speed limit or average travel speeds (at least as current as their information is) on basically every road in their databases. Shouldn't it be possible to get a similar map to Nevada's on California's numbered highways (and probably most alphanumeric inter-county roads)? Has anyone seen such a map? Just the interstates (which I suspect someone with a decent drawing program could do on their lunch hour) won't do. Does Caltrans produce such a map?

Google Maps and the like don't have free access to the APIs and data sets. I mean you can access it, but there are limitations (and they have gotten stricter over the years). I have seen a map at some point where speed limits are put on a map from OpenStreetMap's data, but I can't seem to find the link to it. OSM's data is free to use so it's definitely possible for someone to create one based on their data. Though their data is less complete in many cases than Google (especially on less important things like speed limits), since more of it is crowd-sourced.

I did mean the latter, as in "interstate that does not have a 70 section".

There might be GIS data available, that's how I made the map of Washington's speed limits. Problem there though is getting access to a program that can read and display that data; I just used my work computer to do so. I look into it though and post a map here if I find something since I'd be interested in it too.

If you use Waze's practice editor feature, you can see speed limits along most road segments. They're usually fairly accurate and up to date.

Luckily you have a GIS major here. I have ArcMap on my computer. Assuming I can figure out where Caltrans provides their GIS data, I'm sure I could get something. I'll post again. Fairly busy day but I'll share what I can mock up.

That said, I know I'm not the only one here with access to this stuff, so someone could beat me to the punch .

EDIT: I have no idea if this data is available from an easy source. If sure someone at Caltrans has a shapefile. I'm not seeing anything via Google.
