All of the business loops within Texas are maintained by the Texas Department of Transportation (TxDOT). Interstate 20 (I-20) has 15 business loops in the state, all located in western Texas. Along I-20, TxDOT identifies each business route as Business Interstate 20 followed by an alphabetic suffix. Along Texas Interstates, the alphabetic suffixes on business route names ascend eastward and northward. There are gaps in the alphabetic values to allow for future system expansion. The alphabetic naming suffixes are included as small letters on the bottom of route shields.

I-20 business routes in Texas generally follow the path of the former U.S. Route 80 (US 80) through the central portions of towns now bypassed by the Interstate route.
Business Interstate 20-B (Bus. I-20-B) is a business loop of I-20 that passes through Pecos and Barstow in Reeves and Ward counties.[1] The 13.3-mile (21.4 km) route, commissioned in 1991, begins at I-20 exit 37 and ends at exit 52. In Pecos, the route runs along Third Street. The route has major intersections with US 285, State Highway 17 (SH 17), and three Farm to Market Roads.[2]
The route was originally designated as part of US 80 until US 80 was decommissioned in western Texas in 1991.[1]

Business Interstate 20-D (Bus. I-20-D) is a business loop of I-20 that passes through Monahans in Ward County commissioned in 1991.[3] The 7.2-mile (11.6 km) route begins at I-20 exit 76 and runs along Sealy Avenue, returning to the Interstate at exit 83. The route has major intersections with SH 18, State Highway Spur 57 (Spur 57), and State Highway Loop 464 (Loop 464).[4]
The route, together with Spur 57, was originally designated as part of US 80 until US 80 was decommissioned in western Texas in 1991.[3][5]
The entire route is in Ward County.
Business Interstate 20-E (Bus. I-20-E) is a business loop of I-20 that passes through Odessa and Midland in Ector and Midland counties.[6] The 32.0-mile (51.5 km) loop, commissioned in 1991, begins at I-20 exit 112 in West Odessa and ends at I-20 exit 144 east of Midland.[6][7] In West Odessa and Odessa, the route is known as Second Street and intersects SH 302 and US 385. Between Odessa and Midland, the route intersects SH 349 connecting the business loop to Midland International Airport. In Midland, the route begins as Wall Street and intersects SH 158. At Spur 268, the business loop turns onto Front Street and continues along that street to its terminus.[7]
The business loop follows the previous path of US 80 through Odessa and Midland between 1952 and 1991 when US 80 was decommissioned in western Texas. Before 1952, US 80 in Midland continued along Wall Street following the present Spur 268, Business State Highway 158-B (Bus. SH 158-B), and Spur 269 until returning to the present route. Between 1952 and 1991, this previous alignment in central Midland was signed as a US 80 business route although it carried state loop and spur designations.[8][9][10]

Business Interstate 20-F (Bus. I-20-F) is a business loop of I-20 that passes through Stanton in Martin County commissioned in 1995.[11] The 4.6-mile (7.4 km) route begins at I-20 exit 154 and runs along Front Street through Stanton to its terminus at I-20 exit 158. The route has one major intersection with SH 137.[11][12]
When this section of US 80 was decommissioned on August 28, 1991, this section was designated as State Highway Loop 214 (Loop 214). This designation was replaced by the current Interstate business route designation on March 30, 1995. The number was previously used for State Highway Spur 214 (Spur 214), designated on October 18, 1948, from SH 73 to SH 87. On January 7, 1987, this became part of SH 82.[11][13]

Business Interstate 20-G (Bus. I-20-G) is a business loop of I-20 that passes through Big Spring in Howard County commissioned in 1990.[14] The 5.6-mile (9.0 km) route begins at I-20 exit 174 and runs along Martin Luther King Jr. Boulevard before veering to the northeast and joining Third Street (westbound) and Fourth Street (eastbound) the remaining distance through town. The two streets merge just before rejoining I-20 at exit 179. The route has major intersections with US 87, SH 350, and Farm to Market Road 700 (FM 700).[14][15]
The business loop largely follows the former route of US 80 through Big Spring before December 18, 1964, when US 80 was rerouted around town over I-20. At that time, the former route through town was designated as Loop 402, although it was signed as a US 80 business route until the current Interstate business route was established on June 21, 1990.[14][16]
The entire route is in Howard County.

The route has major intersections with SH 163, SH 208, FM 1983, and runs concurrently for several blocks with Bus. SH 208-B on Colorado City's east side.[20][21]
The business loop follows the route of the former US 80 through Colorado City before January 14, 1963, when US 80 was rerouted along the present Interstate bypass. At that time, the former route through town was designated as State Highway Loop 377 (Loop 377), although it was signed as a US 80 business route. It retained the Loop 377 designation until June 21, 1990, when it was reclassified with its present Interstate business route designation.[20][22] The number will be reused on March 26, 2020, for Spur 377 in Williamson County.[23]

Business Interstate 20-K (Bus. I-20-K) is a business loop of I-20 that passes through Loraine in Mitchell County commissioned in 1990.[24] The 1.6-mile (2.6 km) route begins at exit 224 of I-20 and follows Pacific Avenue through town to I-20 exit 226B. The route has a major intersection with FM 644.[24][25]
The business loop follows along the route of the former US 80 through Loraine until February 26, 1957, when US 80 was rerouted along the present Interstate bypass.

Business Interstate 20-L (Bus. I-20-L) is a business spur of I-20 that serves Roscoe in Nolan County commissioned in 1990.[28] The 1.6-mile (2.6 km) route begins at I-20 exit 235 and proceeds to the northeast before turning east along First Street in Roscoe. The route terminates at Business U.S. Route 84-J (Bus. US 84-J) and FM 608.[28][29]
The business spur follows the path of the former US 80 through Roscoe before 1958 when US 80 was rerouted over the present Interstate bypass. The former US 80 continued from the present eastern terminus of the business spur east along First St. then followed US 84 to the present I-20. On December 19, 1958, the present business spur was designated State Highway Spur 237 (Spur 237) and then as State Highway Loop 237 (Loop 237) on April 15, 1959, even while maintaining the current termini as a true spur. The Loop 237 designation was dropped in favor of the current Interstate business classification on June 21, 1990. Loop 237 was originally designated on September 28, 1950, from US 82 south along Robison Road to US 67 in Texarkana. This route was removed from the state highway system on September 23, 1953.[28][30]

Business Interstate 20-T (Bus. I-20-T) is a business loop of I-20 that passes through Baird in Callahan County commissioned in 1990.[45] The 2.8-mile (4.5 km) route begins at I-20 exit 306 west of Baird with Bus.
