Business routes

All state designated Interstate Business Loops are internally designated as State Route Business Loops by ADOT, being referred to throughout ADOT ArcGIS data and state highway logs as such.[11] For example, all currently state designated I-10 Business Loops in Arizona are referred to as "SB010" which is the Arizona Transportation Information System (ATIS) code for "State Business Route 10" or "SR 10B" for short.[11][12]
