Pasadena to Eagle Rock and Glendale
The Colorado Freeway was first opened to traffic on June 25, 1954. The first segment ran from Orange Grove Blvd in Pasadena west to Avenue 64 in Eagle Rock. The westbound lanes of the Arroyo Seco Bridge were opened a little earlier on October 8, 1953. This first segment included four structures. The largest and most interesting structure was the Arroyo Seco Bridge. It was designed to compliment the 1913 Colorado Street Bridge and still does so quite nicely to this day.
In 1955, the freeway was extended further west from Avenue 64 to Colorado Blvd at Eagle Vista Drive. In 1957, the Golden State Freeway was also extended from Western Avenue in Burbank to Los Feliz Blvd in Glendale. Along with many other interchanges, a freeway-grade exit to Colorado Street was built. This is known as the Colorado Street Freeway Extension and was signed as SR-134.
In 1971, the eastern Colorado Freeway was rebuilt to higher standards. It was widened, repaved, and realigned. It was also renamed the Ventura Freeway. Part of the old Colorado Freeway still exists, however, as the westbound Colorado Blvd exit. The western segment of the freeway still exists almost unmodified and still remains in heavy use. While it is no longer signed, the western segment still remains as a part of State Route 134. One aspect of the western segment is rather unique. It remained as the last freeway in Los Angeles with an intact raised median with no barrier until recently. The median was upgraded to a standard style median in 2016.

Signage
The Colorado Freeway bore many shields. From the western end to Figueroa Street, it was SR-134. At Figueroa Street, SR-134 ended. SR-11 and US 66 Alternate took over at Figueroa. SR-11 then left the freeway at the Linda Vista Blvd exit and headed north to SR-118. US 66 Alternate stayed on the freeway to its eastern end at Orange Grove Blvd and continued east to Arroyo Parkway, ending there. The western segment of the freeway bore only SR-134 shields. In 1964, US 66 Alternate was removed entirely and SR-11 left the Colorado Freeway for the Arroyo Seco Parkway. SR-134 took over the entire freeway and remains there today.

Please check your facts about the Pioneer Bridge, pretty sure this always referred to the 1953 bridge and not the 1913 one.
