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. 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.
