 Interstate 40 (I-40) and I-75, which run roughly parallel to Kingston Pike, siphoned off most of the area's interstate traffic, and most of Kingston Pike's tourism-related businesses closed.Only a few buildings from Kingston Pike's Dixie Lee Highway period have survived to the present day, most notably the 11-70 Motor Court near Farragut, the Naples Restaurant in Bearden, and Dixie Lee Fireworks and the old Court Cafe building at Dixie Lee Junction.With the advent of the automobile in the 1920s, Knoxville's more affluent residents began fleeing urban neighborhoods for suburbs on the city's periphery.
