Princeton LOOP Bus – Princeton NJ

Smith + Manning’s signature frog mascot—playfully encouraging riders to “Hop on, it’s free!”—creates a friendly, engaging identity that boosts awareness and ridership. The Princeton Loop is a free public bus service in Princeton, NJ, operating Monday through Saturday and connecting major destinations such as Palmer Square, Princeton Shopping Center, and the Princeton Dinky Station. With two routes—Loop Local and Loop Express—the iconic green buses are accessible to all and feature convenient “flag stops,” making local transportation in downtown Princeton simple, flexible, and easy to use.
