Naming
Typically, all business routes off the same parent route have the same name on signage. For example, St. Augustine business loop and Fredericksburg business loop are two of the many business routes stemming off US 1, all of which are marked as "US 1 Bus.". But within a state's transportation administration, different business routes may be assigned unique names to differentiate them. For example, Texas has 11 different business routes attached to I-35; while all are signed as "Business Loop Interstate 35", (BL I-35) they are designated by the Texas Department of Transportation as BL I-35-A, BL I-35-B, and so on.
