Texas State Highway Loop 358

A total of seven special routes of U.S. Route 90 exist.

Texas

All of the alternate and business routes within Texas are maintained by the Texas Department of Transportation (TxDOT). U.S. Route 90 has one alternate route and two business routes within the state. Along US 90, TxDOT identifies each business route as Business U.S. Highway followed by an alphabetic suffix. Along Texas U.S. routes, the alphabetic suffixes on business route names ascend eastward and northward. There are gaps in the alphabetic values to allow for future system expansion or for decommissioned routes. The alphabetic naming suffixes are included as small letters on the bottom of route shields.
