About This Route:

Interstate 10 is the backbone of this route, connecting two of the fastest-growing metro areas in the American Southwest, and it’s one of the most heavily used corridors for commercial freight in the country. Arizona doesn’t observe Daylight Saving Time (with the exception of the Navajo Nation), so the time difference between Phoenix and Houston shifts depending on the season — Houston is one hour ahead during Daylight Saving Time (spring through fall) but on the same clock as Phoenix during standard time in winter. That quirk trips up a lot of travelers planning calls or flight connections between the two states.
