Business routes of Interstate 20 in Texas

All of the business loops within Texas are maintained by the Texas Department of Transportation (TxDOT). Interstate 20 has fifteen 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 through the central portions of towns now bypassed by the Interstate route.

Odessa–Midland business loop

Business Interstate 20-E or Bus. I-20-E is a business loop of Interstate 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 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]
