Flint sits at a crossroads of Michigan's freeway system. I-75 runs along the west side of the city between Detroit and Saginaw, and I-69 crosses east-west just south of downtown between Lansing and Port Huron. I-475, the UAW Freeway, loops through downtown and the east side, splitting from I-75 south of the city and rejoining it to the north. US 23 comes up from Ann Arbor and merges into I-75 south of Flint. Dort Highway, Saginaw Street, Miller Road, Corunna Road and Bristol Road are the main arterials, and the Flint River winds through the middle of town.
The I-75, I-69 and I-475 interchanges are where most freeway breakdowns end up, and the stretch of I-75 near Miller Road and Grand Blanc slows with retail and commuter traffic. Many Flint drivers commute south toward Detroit or Ann Arbor, which piles freeway wear onto cars that already face harsh winters. The city and the surrounding townships are built on a wide grid, so once a car is home, a mechanic can usually reach it with no trouble. Wide streets also mean there's usually room to park the service van right behind the car, which keeps driveway jobs quick.
Bishop International Airport is on the southwest side near I-75 and I-69, with surface lots that are easy to work in. Local buses run along the main corridors, and the downtown core around the university campus and the cultural center is compact and quick to get around. Students, hospital staff and downtown workers share the same handful of lots and decks, so a precise location helps the mechanic find the car fast.
