Business Loop I-70 - Frisco
Former Business Route
Signs along Interstate 70 east for Main Street / Exit 201 and west for Colorado State Highway 9 / Exit 203 referenced the "Frisco Business Loop." The 2.3 mile route of Main Street east to SH 9 (Summit Boulevard) north may have been what the 1976 CHD route log classified as "SH 70 (Sec. J)" (Salek, 2014).
