Atlanta boomed when Route 66 was built in the 1920s, but that prosperity faded when the busy road was rebuilt in 1947 to bypass town to the east. New businesses then flourished on the bypass, only to fail again when I-55 replaced the Mother Road in 1977. More recently, renewed interest in historic Route 66 has brought life back into Atlanta. As a stop for the Greyhound Bus Line, many journeys began and ended at the Palms Grill, which opened in 1934 and attracted travelers on Route 66; passengers flipped a switch to light the bottom of its neon sign to alert the bus driver to stop. Downtown cafes and gas stations did more than serve highway travelers, as they were also places where townsfolk gathered to share gossip, negotiate deals, and fall in love. Opened around 1920, the Deep Rock Station on Arch Street was busy with customers when Route 66 ran through downtown Atlanta, and businesses were abandoned when Route 66 bypassed downtown Atlanta in 1947.
