Business Loop I-15 - Norco
Norco is short for "North Corona." Business Loop I-15 here follows Second Street west from Exit 98 to Hamner Avenue (old SR 31) north. Hamner Avenue parallels I-15 north to Sixth Street, which returns Business Loop I-15 to Interstate 15 at Exit 100. The 2.6 mile route is locally maintained. It was not inventoried in the 1991 state signing log.
