Los Angeles County, California Bridges: East Washington Boulevard Bridge across the Los Angeles River

March 1931 (34.0174 Degrees, -118.2230 degrees) Los Angeles River Bridges
For some reason I never photographed the lovely Washington Boulevard Bridge (53C1375), which is just downstream from the Olympic Boulevard Bridge. However, I was able to get a photo of it from the UCLA Library/Digital Collection. It was taken on March 23, 1931, the opening day for this five span T girder bridge on wide pier walls. We can see that the city had continued to build bridges across the Los Angeles River using the 'Beautiful Cities' ethos. This bridge includes large pylons at the four corners decorated with terra cotta images of the people who designed and built this structure. Another drawing by the city (shown below) gives information on the original design and on the seismic retrofit that was done in the 1990s.

Los Angeles County, California River Bridges: East Olympic Boulevard Viaduct across the Los Angeles River

August 1999 (34.02555-118.22501 Degrees) Los Angeles River Bridges
They were working on the East Olympic Boulevard Viaduct when I visited this site (in 1999), which may explain why I don't have a photo of the bridge's substructure. However, the photo above shows a little of the bridge's elaborate ornamentation. In the past, these details would have been accomplished by a sculptor. At the start of the 20th century they were accomplished with forms filled with concrete. The picture below is from a nice collection of photos from the US Library of Congress that were taken in 2002. It looks like they did a good job of restoring the bridge. It was originally the Ninth Street Bridge when it was built in 1925 but the street and the bridge were renamed in honor of the 1932 Los Angeles Olympics.

Los Angeles County, California Bridges: I-10 Bridge across the Los Angeles River

August 1999 (34.0292, -118.2261) Los Angeles River Bridges
After the Seventh Street Bridge, there's a tangle of bridges making up the I-10 San Bernardino/Santa Monica Freeway Bridges. The Los Angeles River Bridge and Overhead (53 2673) is one of six continuous prestressed concrete box girder bridges crossing the river just south of the Seventh Street Bridge. The above referenced bridge was built in 1989 with a single 260 ft span over the river.
