Snow free Interstates

[roadman65]

Other than I-4, I-8, I-10, I-12, and I-19, are there any other interstates that have never received any kind of snow either in dusting or large amounts.   I did not include I-2 as it is very new to the system, but I imagine that when it was solely US 83 it never got any kind of dusting for its decades as a freeway where the interstate is now designated and the same for the I-69E and other two suffixes and when completed they will stop near Victoria that I am sure remains mostly tropical year round.

Now also to consider the three digits of Southern California and I-515 in Nevada which do not get any precipitation, however those around the SF Bay area due get a dusting or two I would imagine as many inland are away from the Pacific Tradewinds that prevent San Francisco from getting snow or long term ice.

I would imagine that I pretty much summed up the completely free of any kind of winter storm precipitation interstates in the nation, or did I leave out any?  Remember intersates like I-5 and I-45 do not count because their northern reaches are heavy into winter weather areas as it is completely free I am talking about.

I-10 gets snow once in a while.  Wouldn't surprise me if the others do too, if you wanted to look. 

Texas interstates reopen after blizzard
From Joe Sutton, CNN

(CNN) -- Authorities reopened Interstates 10 and 20 in west Texas on Friday afternoon after crashes in blizzard conditions caused their closure earlier in the day.

And that's for a full blizzard with closure, not just a dusting.

The higher elevations of I-8 and I-10 probably get snow every once in a while.  I've seen snow along the Mexican counterpart to I-8, Mex 2D, which is at about the same elevation.  And there was some discussion here about de-icing systems proposed in El Paso, for example, which suggests that part of I-10 is vulnerable.  Even San Diego gets occasional dustings, so I-805 is a maybe at best. 

As for the Texas Interstates, one winter San Antonio was crippled for a few days by an ice storm, so I would hesitate to rule out any of the south Texas Interstates. 

But the H- and unsigned PRI- Interstates are pretty safe.  It snows in Hawaii, but rarely below 10,000 feet, and all the H- Interstates are pretty close to sea level.

I can say, from personal experience, it has snowed on I-680.  I was headed southbound in 2002 and encountered snow falling from just south of Dublin to the CA-84 interchange in Sunol.  This happened at night and surprised the hell out of me.  FWIW, the snow did not stick to the pavement.

I've also heard reports of snow on I-280 up around the Crystal Springs Reservoir.  Given the elevation of the Altamont Pass, I wouldn't be surprised if it snowed on I-580 east of Livermore.  The other 3DIs in the S.F. Bay Area, I-380, I-780, I-880 and I-980, I'm pretty sure they're snow-free.

I-215 and I-515 in Nevada have almost certainly been snowed on.   Snow in Las Vegas is rare, but that's because precipitation levels are low - it certainly gets cold enough during the winter, and there was a significant snow storm as recently as 2008.

I have a hard time believing that I-12 hasn't gotten any kind of snow.

The east end of I-4 got "light snow flurries" in 2003:

The flatlands of the Bay Area do get snow, just a light dusting maybe every 20 years or so.  But it has happened.  I've seen Berkeley and Palo Alto with a dusting of snow, not in the same year of course.

I might have speculated about Florida's I-195, 395, and 595, but it did snow in Miami in January 1977 (including on Miami Beach and as far south as Homestead), so I suspect those routes got a bit even though it presumably didn't stick.

[adventurernumber1]

Interstate 10 has probably gotten some snow, despite how far south it runs. I don't have records of snow storms on I-10  but it's especially possible it's snowed on I-10 in places where it's mountainous like western Texas, New Mexico, Arizona, and maybe even California.

Look further up the thread. "kkt" addressed that route.

What about 16?

[adventurernumber1]

What about 16?

I can tell you for certain I-16 has gotten some snow. That being because (I totally forgot when) some years back, Savannah actually got a huge snowstorm. Since I-16 ends in downtown Savannah, I don't see how it wouldn't have gotten some snow.

I have actually witnessed snow on I-10 in east Texas.  I had parked on a downhill slope near a bridge overpass to rest for a while.  Later when I woke up there was snow accumulating above my windshield wipers.  Also police stopped and asked me to move.  He said he was afraid that someone would slide on slick pavement and hit my car.

I know 10 & 12 had parts shut down due to ice last winter.

1989 Jacksonville had a couple inches if snow.. All the bridges over St John's river were closed. In 1977 I think there may have been 6" snow in Jax

I once drove from L.A. to Houston in February and it snowed in Benson, AZ.  And ditto on the snow on 680 over the Sunol Grade.

[PurdueBill]

I've driven on I-10 in El Paso in snow--not a blizzard and it didn't stick much--but really good squalls nonetheless.  As I recall, the Purdue 2002 Sun Bowl team photo was being taken outdoors at Sun Bowl Stadium (just off I-10) at the time, resulting in everyone squinting as they were being hit in the face with the stuff.

On the parts of I-10 in Louisiana I've been on, I've noticed the Bridges Ice Before Pavement signs (not even folding ones, visible year-round) so at least ice is a possible issue if not accumulating snow.  I believe in late 2001 (or 1/02) or so a bowl game in Mobile was played in a nasty snow storm, so it's certainly possible way down south.

[Darkchylde]

I-12 and I-10 (in southeast Louisiana) last got snow in 2008, to my knowledge (I was there at the time.)

I-8 gets closed at least a few times each winter for snow. It gets over 4000' at its highest and sustains over 2000' for quite a few miles.

[SSOWorld]

Technically, I-2 hasn't gotten snow, but the road it follows has had snow

[cpzilliacus]

Might I-10 at Chiriaco Summit, California sometimes get a little snow? 

I have not seen it myself, but it seems that its elevation might be high enough to induce a dusting sometimes.

[empirestate]

Other than I-4, I-8, I-10, I-12, and I-19, are there any other interstates that have never received any kind of snow either in dusting or large amounts.

As other have shown, it would surprise me if even these routes, with the possible exception of I-4, had never seen snow as some point in their lives.

We've mentioned some of the 3dis in Florida already; how about the ones in Southern CA? Are there any that have never been subjected to snowfall, perhaps those that stay further away from the mountains? I know the region does get much colder than FL, but it also is much drier.

[formulanone]

Back in December 2010, I'd heard that FLL experienced an extremely light case of morning flurries, so that might rule out I-595. It didn't snow at all near my house, which was about  twenty miles to the north.
