Bowling Green sits along the Barren River in south-central Kentucky, halfway between Louisville and Nashville on I-65. The interstate runs along the east side of the city, and I-165, the former Natcher Parkway, heads northwest toward Owensboro. US 231 follows Scottsville Road south from downtown and is the city's main shopping corridor, while US 31W runs as Nashville Road to the southwest and Louisville Road to the north. US 68 crosses the city east to west toward Glasgow and Russellville. Barren River Lake to the southeast and Mammoth Cave National Park to the northeast draw weekend traffic on the rural highways around town.
Inside the city, Campbell Lane forms a partial bypass around the south side, and Lovers Lane, Fairview Avenue and Morgantown Road carry much of the crosstown traffic. Scottsville Road backs up at rush hour and on weekends near the interstate, and the Campbell Lane intersections get busy when the plants change shifts. Downtown centers on Fountain Square Park, with older streets climbing toward the hilltop campus. Outside the core, most neighborhoods have driveways and carports, which makes on-site work straightforward. The city has grown quickly, and new subdivisions keep spreading south toward Plano and Alvaton, where country roads now carry more traffic than they were built for.
Bowling Green-Warren County Regional Airport serves general aviation, and most airline travelers drive to Nashville. GO bg Transit runs buses across the city, but most people drive, many commuting to the large manufacturing plants and the Kentucky Transpark industrial park north of town. Travelers on I-65 between Louisville and Nashville also break down here, often far from home.
