Longest Continuous Street?

[Bigmikelakers]

What is the longest continuous street in the United States? It can be more than one name. I mean the longest you can drive on a given roadway until it ends. No turning off of it, etc. I was browsing google maps right now to see how long CA 66 Foothill Bl goes. If you start from Miles Ave in Huntington Park all the way to Garnet Ave east of Redlands, that is about 75 miles of one long road. Using the names of Miles Ave, Soto St, Hungtington Dr, Foothill Bl, 5th St, Greenspot Rd, and Garnet Ave.

How long can you go on I-90 without a TOTSO?

[KEK Inc.]

Technically, Infinite Loop in Cupertino would count (yeah, Mariana Ave technically makes it not a loop). 

But there's countless numbers of looped roads.  There's a pretty big circle in Santa Clara County starting with Hillsdale Ave and looping all the way up to Sunnyvale at Tasman Dr.  Any old US highway also is pretty long.  El Camino Real/The Alameda/Monterey Rd is at least 80 miles long.  Some of the western US routes paralleled by their replacing Interstates are also long.

150 miles. From north of Cheyenne to Henderson, CO, much of its length as US 85.

Beginning at Laramie County Rd 237/Hirsig Rd & Laramie Co Rd 241, if you follow Co Rd 241, the thru route then becomes Co Rd 116, Co Rd 242/Chalk Hill Rd, Co Rd 118, Co Rd 244/Gillaspie Rd, Co Rd 123/Little Bear Rd, I-25 Service Rd West, WY 219/Co Rd 124/Old Yellowstone Rd, WY 219/Yellowstone Rd (into Cheyenne), US 85/Central Ave, the one-way couplet of Central Ave (US 85 SB) & Warren Ave (US 85 NB), I-180/US 85/Central Ave, US 85/Greeley Hwy.

In Colorado, it's just known as US 85, except Oak Ave in Eaton, 8th Ave/Business 85 in Greeley, & 2nd St in La Salle.

The long road finally ends at an interchange at I-76 in Henderson, northeast of Denver, south of Brighton.

[TheStranger]

El Camino Real/The Alameda/Monterey Rd is at least 80 miles long.

Due to the turns Route 82 (and previously, US 101) has to take in downtown San Jose (originally at Market Street, but since the 1980s or so at Montgomery, I think as a consequence of Route 87 being built in the area)...the long continuous street that includes the Peninsula's El Camino Real has never been the road that heads out to Gilroy.

If we consider San Jose Avenue/Route 82 as the north continuation into SF, and not Mission Street (which requires a TOTSO configuration southbound at Flournoy Street in Daly City, dating back to the 1980s)...and we also consider Laguna as the continuation of Guerrero (and Marina Boulevard as the continuation of Laguna) on the north end...

This is the longest one can go without having to turn off to continue - 58.4 miles, from Richardson Avenue (US 101) and Marina Boulevard in San Francisco to Canon Vista Avenue and Alum Rock Avenue in eastern San Jose:

Streets involved: Marina Boulevard, Laguna Street, Guerrero Street, San Jose Avenue, Mission Street, El Camino Real, The Alameda, Santa Clara Street, Alum Rock Avenue.

I suspect that the only competitor for "longest street in the Bay Area" would be Route 1 south of Daly City:

https://maps.google.com/maps?saddr=CA-1+S&daddr=37.5854583,-122.5050047+to:Poplar+Ave&hl=en&ll=36.978078,-122.012959&spn=0.040112,0.055189&sll=36.979912,-122.01313&sspn=0.010028,0.013797&geocode=FTv3PgIdHDqz-A%3BFTKCPQId1Liy-CkrS8VKd3CPgDGSqyLPKwBgaA%3BFTtKNAIddE26-A&mra=dme&mrsp=2&sz=16&via=1&t=m&z=14

Including the freeway section from I-280 to Pacifica, this would be 68.9 miles of road from Daly City to Water Street/Soquel Avenue in Santa Cruz, utilizing Cabrillo Highway, Mission Street, and Water Street.  Excluding the freeway, this is only 63.9 miles long (and it's debatable if Santa Cruz County is part of the Bay Area).

WB:  Columbia County, NY Exit B-1 off the Berkshire Spur to get onto the "free 90" around Albany

[TheStranger]

A candidate for one of the longest single stretches of road in (mostly) California without a TOTSO: US 395 + NV 529's run from Hesperia to Carson City between I-15 and I-580, at...395 miles.

[agentsteel53]

historically, Golden State Highway (old US-99) might have had the same name all the way from Sacramento to Los Angeles.  even more historically, I believe the original Boston Post Road (later the Upper Post Road) was fully in service not too long after the 1683 initial surveying.

[TheStranger]

historically, Golden State Highway (old US-99) might have had the same name all the way from Sacramento to Los Angeles.

Strangely enough I feel like the longest extent of a continuous Golden State Highway was...in the 1950s when the Golden State Freeway was finished!

This is because of the multiple names of the LA stretch (San Fernando Road et al.) and the usage of Stockton Boulevard for the original 99 corridor throughout Galt, Elk Grove, and Sacramento.

The northernmost street on the 99 corridor to still use the Golden State name is in Keyes (just past Turlock).

[agentsteel53]

so maybe just between Stockton and the foot of the grapevine?  (maybe the 99-6 junction or not too far north of it? 99-7?)

[TheStranger]

so maybe just between Stockton and the foot of the grapevine?  (maybe the 99-6 junction or not too far north of it? 99-7?)

I feel like that probably might be it though there are spots of sporadic other street names in use.  (Even if the GSH extended north, I don't recall it being noted as such in 1930s maps of Sacramento.)

The furthest extent thus might have been from about Turlock or Modesto to the East Los Angeles Interchange (but only briefly).

[DTComposer]

It seems like there needs to be a qualifier: longest street within one urban area, or longest street which is not a freeway or expressway, or something. From the OP's submission, I would then submit Sepulveda/PCH/Camino Las Ramblas from Mission Hills to San Clemente, 91 miles:

http://goo.gl/maps/r1aXM

I was surprised there aren't more candidates in the L.A. area, given its breadth, but many of the promising routes have been cut off/subsumed by freeway alignments.

[leroys73]

Is this street or highway we are talking about?  I understand that US 83 is the longest "non broken" US route. 

[ftballfan]

Technically, Infinite Loop in Cupertino would count (yeah, Mariana Ave technically makes it not a loop). 

But there's countless numbers of looped roads.  There's a pretty big circle in Santa Clara County starting with Hillsdale Ave and looping all the way up to Sunnyvale at Tasman Dr.  Any old US highway also is pretty long.  El Camino Real/The Alameda/Monterey Rd is at least 80 miles long.  Some of the western US routes paralleled by their replacing Interstates are also long.

The Tasman/Hillsdale loop is very long, starting from Tasman Dr at Morse Ave in Sunnyvale and using Tasman Dr, Great Mall Dr, Capitol Ave (some of which is expressway), Hillsdale Ave, Camden Ave, San Tomas Expy, Montague Expy (including an intersection with Great Mall/Capitol), and Landess Ave before ending at Piedmont Rd in San Jose.

Not quite continuous though as Capitol Avenue intersects Capitol Expressway and becomes Excalibur Drive there.

From west of Palm Beach to Miami. Most of it is US-441:

However, this is debatable, as this route runs thru the I-95/FL turnpike/Palmetto expwy interchange and may be cut to there, resulting in a 60.5 mile drive without a TOTSO.

[agentsteel53]

Is this street or highway we are talking about?  I understand that US 83 is the longest "non broken" US route.

define "non-broken"?  US-20 is broken, but US-6 is not.  or does US-6 no longer count because it has been truncated?  that eliminates US-50, US-40, several others... but (just as an example) US-1 is longer than US-83 and that is fundamentally unchanged from its 1938 extension to Key West.

not multiplexed with an interstate?  US-83 is the same road as I-35 heading out of Laredo briefly, just as one example.

so that leads to the question - what is the longest US route which is not multiplexed with an interstate along any of its length?  US-281 almost qualifies, getting all the way from Canada to I-44 without multiplexing with an interstate.

[NWI_Irish96]

I'm wondering how the I-65/I-70 junctions in Indy are classified with regards to TOTSO?

My gut says 101 would be pretty high on the list if not #1.  Can't think of any multiplexes off the top of my head.
