Interstate 17 currently has no business routes.
Black Canyon City|
|Business Loop I-17 followed Old Black Canyon Highway (former Arizona 69) north 3.0 miles through Black Canyon City. The route branched west from Exit 242 near Rock Springs and returned to I-17 at a modified diamond interchange (Exit 244) by the abandoned Black Canyon Greyhound Park.|
The business route was subsequently transferred from state to local maintenance, which led to its decommissioning due to ADOT policy of not signing business loops on non-state maintained roadways.
Until 2011, Business Loop I-17 was signed at both ends from the freeway mainline in each direction.
No AASHTO action was taken to eliminate the business route from Interstate 17.
