Business Loop I-15/I-84 - Brigham City, Utah
Southbound Business Loop I-15/Business Loop I-84/Utah 13 at Junction U.S. 89-91. U.S. 89 continues south straight ahead, while U.S. 91 heads due west from here to end at the interchange with Interstates 15-84 near Brigham City. Dan Stober 03/15/01
Southbound U.S. 89-91 split at the intersection with Business Loop I-15/Business Loop I-84/Utah 13 in Brigham City. U.S. 91 turns right toward Interstate 15-84 along with the business loop, while U.S. 89 continues south toward Ogden. Dan Stober 03/15/01

Business Loop I-24 - Paducah, Kentucky
Business Loop I-24 shield in Paducah. H.B. Elkins 06/00
Like the downtown spurs and loop in Sioux Falls, South Dakota, Paducah has used the downtown loop concept for its Business Loop I-24. However, some of the downtown loop shields have been replaced with business loop shields for Kentucky's only business route. H.B. Elkins 06/00
Business Loop I-25 - Socorro, New Mexico
Business Loop I-25 and U.S. 60 are briefly co-signed in Socorro. The business loop follows old U.S. 85. James Allen 09/00
Northbound Interstate 25 approaching Exit 150, Junction Business Loop I-25 and U.S. 60 into Socorro. James Allen 09/00
Business Loop I-25 - Las Vegas, New Mexico

Business Loop I-25 - Walsenburg, Colorado
Northbound Interstate 25 approaching Exit 49, Junction Business Loop I-25 into Walsenburg (and to westbound U.S. 160). Mike Ballard 1998
Business Spur I-126 - Columbia, South Carolina
Business Spur I-126 and U.S. 76 overhead shields on Elmwood Avenue. Paul Martin 2000
Business Loop I-27T - Hale Center, Texas
Southbound Interstate 27 reaches Exit 38, Junction Business Loop I-27T/Main Street (former U.S. 87) to Hale Center in Hale County. The loop rejoins Interstate 27 at Exit 36. Robert Lee 06/17/06
Business Loop I-27U - Plainview, Texas
Southbound Interstate 27 reaches Exit 53, Junction Business Loop I-27U (former U.S. 87) in Plainview in Hale County. The loop rejoins Interstate 27 at Exit 45. Robert Lee 06/17/06
Downtown Spur I-29 - Sioux Falls, South Dakota
Northbound Interstate 29 approaching Exit 79, Downtown Spur I-29 and South Dakota 42 east into Sioux Falls. Bill Burmaster 2003
Southbound Interstate 29 approaching Exit 79, Downtown Spur I-29 and South Dakota 42 east into Sioux Falls. Bill Burmaster 2003
Eastbound Downtown Spur I-29 and South Dakota 42 east into Sioux Falls. Business Spur I-29 is signed as "Downtown Spur I-29" on all but one shield along eastbound 12th Street as it approaches downtown Sioux Falls. Bill Burmaster 2003
Another eastbound Downtown Spur I-29 shield along eastbound 12th Street. Bill Burmaster 2003
This is the only remaining Business Spur I-29 shield left along eastbound 12th Street (South Dakota 42). Bill Burmaster 2003
The Downtown Spur reaches its end after South Dakota 42 passes South Dakota 115/Minnesota Avenue. Note the pull-through sign still refers to Downtown Spur I-29 east. Bill Burmaster 2003
The END signage changed a bit between 2003 and 2005 as shown here. Jeff Morrison 06/26/06
Like other business loops in South Dakota, the end of Downtown Spur I-29 is well signed. Bill Burmaster 2003
Now looking in the opposite direction, westbound Downtown Spur I-29 begins by following South Dakota 42 west out of downtown Sioux Falls. Downtown Spur I-29 ends on eastbound 11th Street, and it begins on westbound 10th Street. This shield shows the first westbound shield on 10th Street. This intersection would have been the intersection of U.S. 77 and U.S. 16, but Sioux Falls no longer has any U.S. highways. Jeff Morrison 06/26/06
Downtown Loop I-229 - Sioux Falls, South Dakota
Northbound Interstate 229 at Exit 3, Junction Downtown Loop I-229/South Dakota 115/Minnesota Avenue north. Bill Burmaster 2003
Northbound Interstate 229 at Exit 6, Junction Downtown Loop I-229/South Dakota 42/10th Street west. Bill Burmaster 2003
Northbound Downtown Loop I-229 departs from northbound South Dakota 115/Minnesota Avenue onto eastbound South Dakota 42 in downtown Sioux Falls. Jeff Morrison reports: "The last northbound assembly shows (Downtown Loop I-) 229 heading east with SD 42. The first SD 42 sign east of this intersection doesn't have a Loop 229 shield, but that could be for a variety of reasons (forgot after construction, or no space because all of them in town were side-by-side and a 42/229 shield set couldn't work at that spot). It IS signed from I-229 at both ends northbound - as 'Business,' if you look hard. I did not drive SD 42 to check east-west." Jeff Morrison 06/26/06
Southbound Downtown Spur I-90/South Dakota 115/Minnesota Avenue at Junction Downtown Loop I-229 and South Dakota 42. Bill Burmaster 2003
This set of reassurance shields on southbound Downtown Loop I-229 and South Dakota 115/Minnesota Avenue show that the business (downtown?) loop is still well-signed, even if it appears on few if any maps. Jeff Morrison reports, "Downtown Loop I-229 is alive and well, at least according to the signage on SD 115, its north-south piece. There was a 229 with every 115 from SD 42 to I-229, and the sign backs indicated they were put up in 2003." Jeff Morrison 06/26/06
Southbound Downtown Loop I-229 ends along South Dakota 115/Minnesota Avenue once it reaches Interstate 229 south of downtown. Jeff Morrison 06/26/06
Business Loop I-35 - New Braunfels, Texas
Farm-to-Market Road 725 at Junction Business Loop I-35H and Business Texas 46 in New Braunfels. Jeff Royston 08/00

Westbound U.S. 30 at Exit 151A, Junction Business Loop I-35 and U.S. 69/Duff Avenue in Ames. Adam Wallace 2000
Business Spur I-40 - Winslow, Arizona
The western end of Business Loop I-40 connects to Business Spur I-40, and there are only shields for it at its western end. Looking north on the eastbound Business Spur I-40 as it prepares to cross the bridge over the Burlington Northern/Santa Fe (BNSF) main line. It curves east back toward the west end of the Business Loop I-40. Jim Mullady 02/01
Looking south approximately 200 feet south of bridge and other sign. These are the only two signs on the entire route, about 1.5 miles. Jim Mullady 02/01
Close-up of the previous photo. Jim Mullady 02/01
Business Loop I-40 - Albuquerque, New Mexico
Business Loop I-40 and U.S. 66 are both cosigned in this picture along Central Avenue in Albuquerque. Casey Cooper 1998
Business Loop I-40 - Tucumcari, New Mexico
Business Loop I-40 and Historic U.S. 66 diverge from eastbound Interstate 40 near Tucumcari at Exit 329, Junction Business Loop I-40, U.S. 54, Historic U.S. 66, and Texas Trail. Notably, U.S. 54 and U.S. 66 used to meet here and again converge in downtown Chicago before both routes were retracted out of the Windy City. The loop returns to Interstate 40 at Exit 335. Robert Lee 06/17/06
Business Spur I-40 - Glenrio, Texas
Business Spur I-40 departs from Interstate 40 at Exit 0, but it is signed as a business loop into Glenrio. Robert Lee 06/17/06

Business Loop I-40 - Erick, Oklahoma
Business Loop I-40 and Historic U.S. 66 diverge from eastbound Interstate 40 near Erick at Exit 5, Honeyfarm Road. The business loop rejoins Interstate 40 at Exit 11. Robert Lee 06/17/06
Business Loop I-40 - Elk City, Oklahoma
Business Loop I-40 and Historic U.S. 66 diverge from eastbound Interstate 40 near Elk City at Exit 32, Junction Oklahoma 34 (left exit). The old circular shield was still in use at the time this photo was taken, even though newer state outline shields were replacing the circular shields within the Sooner State. The business loop rejoins Interstate 40 at Exit 41. Robert Lee 06/17/06
Business Spur I-44 - St. Roberts, Missouri
These photos show how Business Spur I-44 and Business Loop I-44 are signed in and around Saint Robert. We wonder how confusing people find the intersection between Loop 44 and Spur 44? There is only one other instance of a loop intersecting a spur, and that occurs in Winslow, Arizona (see Business Spur I-40, above). There are no similar sign assemblies at that intersection. Mark Roberts 1999
Business Loop I-55 - Springfield, Illinois
Signage for the split between Interstate 55 south, Interstate 72/U.S. 36 west, and Business Loop I-55/U.S. 66 north as seen along Interstate 55/72 south in Springfield. Stephen Summers 10/00

Business Spur I-75 - Bay City, Michigan
Westbound Business Spur I-75 and Michigan 25 reassurance markers on Jenny Street. Walter R. Stasinowsky and William Stasinowsky 02/01
Eastbound Business Spur I-75 and Michigan 25/McKinley Avenue east at Junction Michigan 84/Washington Avenue. This is the eastern terminus of Business Spur I-75. McKinley Avenue is a one-way street eastbound; the other direction (westbound) follows 7th Street through Bay City. The "West Business Spur I-75" shield is placed to allow motorists to travel the one block north on Michigan 84 to westbound Michigan 25/7th Street. Walter R. Stasinowsky and William Stasinowsky 02/01
Westbound Business Spur I-75 and Michigan 25 end as the highway transfers into the U.S. 10 freeway en route to Midland at the interchange with Interstate 75 and U.S. 23. There is neither an "END Business Spur I-75" nor an "END Michigan 25" sign. As you enter this interchange from the west, however, there is a "U.S. 10 ENDS" sign. Walter R. Stasinowsky and William Stasinowsky 02/01
At the time this photo was taken, neither southbound nor northbound Interstate 75 had signage for Business Spur I-75; here it is solely signed on southbound as Michigan 25 east/Exit 162A. Walter R. Stasinowsky and William Stasinowsky 02/01
Business Loop I-80 - Pine Bluffs, Wyoming/Nebraska
Westbound Business Loop I-80 and northbound Nebraska Link 53B begin at Exit 1 (East Pine Bluffs interchange) and head north to meet U.S. 30. The business loop and U.S. 30 turn west to enter Wyoming and the town of Pine Bluffs. Andy Field 08/98

Business Loop I-82 - Yakima, Washington
Although not marked on many maps, there is a Business Loop I-82 that serves the city of Yakima along First Street (old U.S. 12-97). Mark Bozanich 2000
Business Loop I-84 - Bliss, Idaho
The reverberation of a sunset frames this photo of eastbound Business Loop I-84 and U.S. 30 in Bliss. In Idaho, scenic U.S. and state routes are signed with a brown shield rather than a black and white shield. Zach Maillard 08/00
Business Spur I-385 - Greenville, South Carolina
Southbound U.S. 276 approaches Interstate 385 south (left turn) and Business Spur I-385 northwest into downtown Greenville. This is one of two shields left that sign the business spur. Carter Buchanan 2001
Business Spur I-585 - Spartanburg, South Carolina
Northbound U.S. 29 in Spartanburg meets Business Spur I-585 north and U.S. 176/South Carolina 9. The business spur heads north and becomes the freeway Interstate 585 less than a mile northwest of here. Carter Buchanan 2001
Business Loop I-90 - Ellensburg, Washington
The business loop in Ellensburg connects Interstate 90 between Exit 106 and Exit 109 via old U.S. 10 and old U.S. 97. Business Loop I-90 is well-posted thru town but there are no signs at the Interstate 90 exits. Mark Bozanich 05/99
Business Loop I-90 - Cle Elum, Washington
Business Loop I-90 follows Old U.S. 10 in Cle Elum between Exit 84 and Exit 85. Mark Bozanich 06/99

Southbound Downtown Spur I-90/South Dakota 115 at Benson Road, which leads east to Interstate 229. Bill Burmaster 2003
Reassurance markers for southbound Downtown Spur I-90 and South Dakota 115. Bill Burmaster 2003
Downtown Spur I-90 ends once it reaches its intersection with South Dakota 42. South Dakota 115 continues south (South Dakota 115 is former U.S. 77, which has been decommissioned in South Dakota due to the presence of Interstate 29). According to Jeff Morrison, Downtown Spur I-90 was rerouted in the early 2000s onto Benson Road and Minnesota Avenue instead of North Drive. He believes that this reroute leaves much to be desired as it is less direct and has no advance signs at the turn south from Benson Road onto Minnesota Avenue at the east end of the airport. There is no "End" at the north end. Jeff Morrison 06/26/06
Downtown Spur I-90 used to be signed as Business Spur I-90 in Sioux Falls, as shown in this photo. Ed Wilson 08/00
Business Loop I-94 - St. Joseph, Michigan
Eastbound Interstate 94 mileage sign for the next two exits - Exit 23, Junction Business Loop I-94 and Exit 27, Junction Michigan 63 (old U.S. 33). Marc Fannin 2000
