Denver also has a nearly complete beltway known as "the 470's". These are SH 470 (also known as C-470), a freeway in the southwest Metro area, and two toll highways, E-470 (from southeast to northeast) and Northwest Parkway (from terminus of E-470 to US 36). SH 470 was intended to be I-470 and built with federal highway funds, but the funding was redirected to complete conversion of downtown Denver's 16th Street to a pedestrian mall. As a result, construction was delayed until 1980 after state and local legislation was passed.[148] I-470 was also once called "The Silver Stake Highway", from Gov. Lamm's declared intention to drive a silver stake through it and kill it.

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" built as a state highway is the present-day SH 470, which is a freeway for its entire length.
