Colorado Boulevard (or Colorado Street in Glendale and 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). Route description West end The west end of Colorado Boulevard is composed of two segments: a disconnected surface street segment of Colorado Boulevard, and the Colorado Street Freeway Extension. Colorado Boulevard begins at a cul-de-sac near the Los Angeles River in Los Angeles and continues east. The road passes on/off-ramps to the eastbound Colorado Street Freeway Extension, and Edenhurst Avenue, which provides access to the westbound freeway. The segment terminates at West San Fernando Road near the Los Angeles-Glendale city limits, and picks up across the railroad corridor at San Fernando Road in the city of Glendale as Colorado Street. The Colorado Street Freeway Extension begins at Interstate 5 (Golden State Freeway) as a short freeway spur, originally carrying State Route 134 until it was moved north onto the Ventura Freeway, but is still maintained by Caltrans. After crossing the Los Angeles River, there is an eastbound interchange with Colorado Boulevard (signed as Edenhurst Avenue), a westbound interchange with Edenhurst Avenue, and an eastbound interchange with Elk Avenue (signed as San Fernando Road). The freeway then terminates at Colorado Street in Glendale. Traffic exiting the Colorado Street Freeway Extension cannot turn west onto Colorado Street, but eastbound traffic from Colorado Street can enter the freeway. The freeway's entrances are signed as entrances to Interstate 5. At the east border of Glendale, Colorado Street becomes Colorado Boulevard as it crosses State Route 2 (Glendale Freeway) into Los Angeles (specifically, the neighborhood of Eagle Rock). Another short freeway spur splits west of the intersection with Figueroa Street, heading northeast to the Ventura Freeway. This spur also carried SR 134 after the Ventura Freeway was built to the east but before it was built west of the split with the spur. After crossing Figueroa Street, Colorado Boulevard splits from Linda Vista Avenue and then passes over the Arroyo Seco on the Colorado Street Bridge into Pasadena. Through Pasadena In Pasadena, Colorado Boulevard crosses the short State Route 710 spur and forms the north end of State
