Birmingham grew up in Jones Valley between long ridges, and its roads follow the terrain. I-20 and I-59 run together through downtown on a northeast-to-southwest line toward Atlanta and Tuscaloosa, while I-65 crosses them at the downtown interchange locals know as Malfunction Junction and continues south toward Hoover and Montgomery. I-459 swings around the south side as a bypass linking Bessemer, Hoover and the Trussville area, and I-22 heads northwest toward Memphis.
The over-the-mountain commute is where cars get tested. US 280 carries heavy traffic from the Red Mountain Expressway out through Shades Valley and into Shelby County, and its signalized stretches are a daily grind of braking and idling. US 31 climbs over Red Mountain past Vulcan and on over Shades Mountain into Vestavia Hills, with grades that punish a slipping transmission or an engine that runs hot. A stall in the cut through Red Mountain or a car stranded on the 280 shoulder is a common reason people look for on-site help.
Off the freeways, the city is easy to reach. Highland Avenue, Clairmont Avenue and the numbered avenues downtown connect Southside, Avondale and Highland Park, and most suburbs sit a short run from an interchange. Birmingham-Shuttlesworth International Airport lies just northeast of downtown off I-20/59, so airport lots are a straightforward stop. Public transit is limited to bus routes, which is one more reason a car that won't start at home is better fixed in the driveway than towed across town.
