Colorado Boulevard (or Colorado Street in Glendale and parts of Arcadia) is a major east–west street in Southern California. It runs from Griffith Park in Los Angeles east through Glendale, the Eagle Rock section of Los Angeles, Pasadena, and Arcadia, ending in Monrovia. The full route was once various state highways but is now locally maintained in favor of the parallel Ventura Freeway (SR 134) and Foothill Freeway (I-210).
