In 1913 the Colorado Street Bridge was dedicated . This structure curves across the Arroyo accessing Eagle Rock , Glendale , and the San Fernando Valley . During the Stock Market Crash of 1929 and the subsequent Great Depression of the 1930s , the bridge was a jumping off point for many committing suicide , whereby it received the ignoble name of " Suicide bridge . " By the 1980s the bridge fell into disrepair as chunks of concrete dropped from its face to the armory parking lot in the Arroyo below . After the San Francisco – Oakland Bay Bridge failure in the 1989 Loma Prieta earthquake , the Colorado Street Bridge was closed as a precautionary measure . Eventually assistance from the Federal Bridge Repair and Replacement Fund and other local governmental agency discretionary funds provided funding for the complete restoration and seismic retrofit of the bridge . The total project budget amounted to $ 24 million , and the Colorado Street Bridge was reopened on Dec. 13 , 1993 , on time and on budget
