1900:  The Automobile Club of Southern California files Articles of Incorporation with the State of California.

The Club is founded by ten car enthusiasts in Los Angeles.

While the first automobiles took to the streets in Los Angeles in 1887, by 1923 there were 430,000 cars registers in the city — one for every three people.

1913:  Pasadena’s Colorado Street Bridge is dedicated.

More than 3,000 local residents turn out for the ceremonies.

The structure was replaced by the Arroyo Seco Bridge in 1951 as part of the Colorado Freeway in Pasadena.
