Charlotte's freeways form a wheel around Uptown. I-77 runs north toward Huntersville and Lake Norman and south across the state line toward Rock Hill, I-85 slices northeast toward Concord and southwest toward Gastonia, and I-277 wraps the center city in a tight loop. I-485 circles the whole county as the outer beltway, touching Ballantyne, Matthews, the University area, Huntersville and the airport. Independence Boulevard, US 74, carries the east side toward Matthews and Monroe.
The interchanges are where the trouble concentrates. The junction of I-77 and I-85 north of Uptown, the I-485 and I-77 merge near Ballantyne and the run of I-77 up toward Lake Norman all clog at rush hour, and a car that overheats or loses its alternator there is stuck on a narrow shoulder with heavy trucks passing. Away from the freeways, Charlotte's streets follow old creeks and wagon roads rather than a grid, and many change names along the way, so a mechanic who knows the shortcuts between South Boulevard, Park Road and Providence Road saves real time getting to a driveway.
Charlotte Douglas International Airport sits on the west side off Billy Graham Parkway and I-485, and its long-term lots and decks are common places for a car to refuse to start after a trip. The LYNX Blue Line light rail runs from University City through Uptown and South End to the I-485 station at its southern end, and many commuters ride it while their car is repaired at home or at a park-and-ride lot.
