State Highway 75 - Platte Canyon Road

Home » Guides » Colorado » State Highway 75 - Platte Canyon Road

Colorado 75 follows Platte Canyon Road north from a RIRO with C-470 to Bowles Avenue through the southern suburbs of Denver. The state highway formerly extended further east along Bowles Avenue and Littleton Boulevard through the city of Littleton and north along Broadway to U.S. 285 (Hampden Avenue). The section of Colorado 75 between U.S. 85 (Santa Fe Drive) and Broadway was decommissioned by the late 1990s. The remainder along Bowles Avenue was dropped from the system in 2010. The segment on Broadway was subsequently decommissioned in 2011.1
