Do Business Spurs Exist?

I know Business loop routes exist, where they connect to the original route on both sides, but I've never seen a business spur route (connects to the original route on one side).  Do these exist? Where are they?

Travel Mapping can show you all of the Interstate loops and spurs:

Look for the ones marked as BS instead of BL.  Loops are clearly far more common, but there are a good number of spurs out there.

In Michigan, we have BS I-75 for both Bay City and Sault Ste. Marie, and BS I-196 for Grand Rapids. The Bus. US 131 at Hart is a business spur, as is Bus. M-60 at Niles and Bus. US 2 in Ironwood. Then you have the case of Bus. M-32 at Hillman which no longer connects to M-32 at its southern end and runs into town as a spur. We also have the unsigned BS I-375 in Detroit.

Historically speaking, we had other business spurs (BS I-69 Port Huron, BS I-96 Muskegon, BS I-96 Portland, BS I-96 Detroit, BS I-696 Detroit)

Proper Interstate shields indicate whether the business route is a loop or a spur, although there are several occurrences in Michigan where any available green-and-white shield was installed. 





US 89

There is one from I-70 into Salina, UT. (It's also concurrent with US-50 and US-89.)

Yes, several are posted in Arizona, Colorado, Missouri, Utah etc. We have all of them listed at http://www.interstate-guide.com/business-routes/
Many are unsigned and exist for inventory purposes, such as those for I-70 and I-76 in Colorado and for I-29 and I-90 in South Dakota.

I-85BL (Greensboro, NC) 
I-85BL (Lexington, NC)
I-95BL (Fayetteville, NC)

What about US or state highways that are listed as business spurs? Any occurrences of those out there? Maybe even signed?

Texas has a few I think. South of Pharr where US 281 makes a turn eastward, there's a spur that makes a connection to Mexico.

And I believe US 64has one (maybe not signed as a spur) in Augusta, AR

TX 114 has a 'spur' in Rhome, it only goes as far as its intersection with Business US 81, not all the way through like Bus US 81 does.

In Corsicana, I think US 287's BUS route is only a spur between the I-45/US 287 split on the SE side of town, and its intersection with Business I-45.  This is just from various GSV angles, but it's hard to tell because of the varying signage treatments along and off of I-45 there.

Why both of the above examples wouldn't go all the way through town, I'm not sure.

California has state business routes, but not differentiated between loops and spurs. I think they're all loops, though at least one begins at one route and ends at another, with only an implied concurrency on the second route to bring the business route back to its parent.

There is a signed US 95 spur between Weiser ID and Weiser Jct OR which used to be US 630.

Supposedly, there is a US 52 spur in Charleston SC, although it is unsigned.

Former I-8 Bus. in San Diego began at SR 163.

Well, if we're just talking about any old spur, there are 46 of them scattered throughout Georgia (source: Travel Mapping). I can't say that I've ever heard of a "business spur" other than the green-Interstate variety.

Beltway mentioned the east end of I-20 that connects the freeway with US 76 in Florence.  Its basically an arterial extension of the interstate so it cannot return to its parent.

The real rare ones are "Downtown Spur/Loop" Interstates that I think were (and may still be) used in the Dakotas in some places instead of Business Spur/Loop Interstates. They are still Interstate business routes for all practical purposes
