Phoenix is laid out on a grid that stretches across the whole Valley, and almost everyone drives it. I-10 cuts east-west through downtown and splits toward Tucson and Los Angeles. I-17 runs north from the downtown Stack toward Flagstaff, and SR 51 parallels it through the central corridor to the Loop 101. The 101 and 202 loops wrap the metro and connect Phoenix to Scottsdale, Tempe, Chandler and the West Valley. US 60, the Superstition Freeway, carries the East Valley commute.
Those freeways are where a mobile mechanic earns their keep. The I-10 Broadway Curve and the I-17 interchange back up every weekday morning and evening, and a car that stalls in that traffic in July is a dangerous place to be. Surface streets are just as relevant: the mile grid means most neighborhoods are a short hop from a wide arterial, so a mechanic can reach a driveway in Ahwatukee, a parking garage in Midtown or an office lot near the Deer Valley Airpark without fighting the freeways at all.
Sky Harbor sits in the middle of the city, which makes airport parking lots and the hotel rows along 44th Street and the I-10 corridor common service locations. The light rail runs from Mesa through Tempe and downtown to north Phoenix along Central Avenue, and plenty of people ride it in while their car gets fixed at home.
