Business Loop I-5 - Solana Beach and Del Mar

This instance of Business Loop I-5 followed a combination of San Diego County S6 (Via de la Valle), San Diego County S21 (Coast Highway 101 / Old U.S. 101) and San Diego County S8 (Lomas Santa Fe Drive). A handful of signs, including an end assembly, were posted for the route at the Via de la Valle exit near the Del Mar Racetrack south of Solana Beach. The remainder of the loop is completely unsigned and the mainline "Route 5 Business Next Right" sign was removed from the northbound lanes in 2000.
