Memphis sits on the bluffs above the Mississippi River, and its highways are built around river crossings and loops. I-40 comes in from Arkansas over the Hernando de Soto Bridge and swings around the north side of the city before heading east toward Nashville, while I-55 crosses on the older bridge to the south and continues into Mississippi. I-240 forms the inner loop around the south and east sides, and I-269 makes a much wider arc through Collierville and north Mississippi. Sam Cooper Boulevard runs east from Midtown as a short freeway, and Poplar Avenue carries the main east-west surface traffic out through East Memphis and Germantown.
For a mobile mechanic, those loops shape the day. The I-240 and I-40 interchanges on the east side back up at rush hour, the bridge approaches slow down whenever there's a wreck, and Lamar Avenue, the old US 78 freight route through southeast Memphis, carries a steady stream of trucks headed to the distribution centers near the airport. Surface streets like Union, Summer, Winchester and Elvis Presley Boulevard reach almost every neighborhood, so a mechanic can get to a driveway in Cooper-Young, an office lot in East Memphis or an apartment complex in Hickory Hill without touching the interstate.
Memphis International Airport sits south of the city and doubles as a major air-cargo hub, so its long-term lots and the warehouse district around it are common service locations. MATA runs city buses and the Main Street trolley downtown. The Medical District between downtown and Midtown, home to several major hospitals and the University of Tennessee Health Science Center, is one of the densest parking areas in the city.
