Street View 


The Colorado Street Bridge is an eleven-arched reinforced concrete structure, the longest and highest bridge of its time. It was the first high bridge across the Arroyo Seco, and is an important visual landmark in Pasadena. Through its design and construction, the bridge represents the advancing concrete technology of the twentieth century and the ornamental aesthetic of the late nineteenth century. The Colorado Street Bridge was designed by one of the nation's foremost bridge engineers, and constructed by a well-known California builder. The local community played an important role in planning and funding construction. -- Historic American Engineering Record (HAER CA-58)
