Interstate 17

Cool Features

I-17 was the first segment of freeway that was built in Phoenix in the mid 1950s.

I-17 is the first Interstate freeway in Arizona to get a DDI interchange. It can be found at Happy Valley Rd. The first DDIs in the entire state can be found on Loop 202. However, the DDIs on Loop 202 are only half DDIs. The Happy Valley DDI is the first full DDI in the state.

I-17's mile markers begin at mile 194 instead of 0. The reason for this is because I-17's mile markers were inherited from AZ 69. AZ 69's mile markers came from old US 89 at mile 201. ADOT used to begin mile markers for highways equal to the mile markers on the highway it branches from. This resulted in the current situation.
