State Highway 470 (C-470, SH 470) is the southwestern portion of the Denver Metro area's beltway. Originally planned as Interstate 470 in the 1960s, the beltway project was attacked on environmental impact grounds and the interstate beltway was never built. The portion of "Interstate 470" that was built as a state highway is the present-day SH 470, which is a freeway for its entire length.
SH 470 begins in Golden, Colorado, starting south from its western terminus at US 6 (6th Avenue) near the intersection with Johnson Road. The highway has interchanges with Interstate 70, State Highway 8, and U.S. Highway 285, then curves to the east. The eastbound portion of SH 470 has interchanges with State Highway 121 (Wadsworth Boulevard), State Highway 75 (Platte Canyon Road), U.S. Highway 85 (South Santa Fe Drive), and State Highway 177 (South University Boulevard). The eastern terminus is the interchange with I-25. Beyond the eastern terminus, the direct continuation of SH 470 becomes the E-470 tollway.
