Riverside Drive Bridge (Arroyo Seco)
Riverside Drive Bridge with Southward View up from San Fernando Road
Riverside Dr. Crossing at the LA River where it meets the Arroyo Seco
Why the Long Name
Written by David Kimbrough
Riverside Drive runs parallel to the Los Angeles River for many miles, from this spot where the Los Angeles River and the Arroyo Seco meet to far into the San Fernando Valley. Riverside Drive crosses the Los Angeles River again about 10 miles north on the other side of Griffith Park where Riverside Drive crosses into Burbank. Riverside Drive was originally known as Los Feliz Road and curved around the hillside to link up with Buena Vista Street.
Los Angeles Times - December 20, 1899
On the 29th inst., the city expects to sell to the Southern Pacific Railway Company about five acres of land located just below Los Feliz Road bridge where it crosses above Buena Vista street. The sale is in the furtherance of a plan to straighten the channel of the river at the point, and thus lessen the danger of overflow along the west bank. Once or twice in the past, during periods of heavy rainfall, the river has broken the levee, and following the old channel of the river, has flooded Alameda street and the cellars of the business house on Los Angeles Street.
- Warren Deck truss bridge over Los Angeles River on Riverside Drive in Los Angeles
- Glassel Park, California, Los Angeles County, California
- Replaced by a new bridge just to the northwest
- Future prospects
- The project proposes to demolish the existing bridge over the LA River, concrete approach spans over Metrolink and Ave 19 East and West roadways, and the viaduct structure (designated as Riverside Dr Viaduct, 53C-1932, W.O. E700010) nearly at 90 degrees to the river-crossing bridge.
A new bridge which includes a bike path is proposed along a single, smooth curve alignment of approximately 420-ft radius. A roundabout of approximately 150-ft diameter will be constructed at the intersection of Riverside Dr and San Fernando Rd to achieve capacity enhancement through improved traffic effiency. The bridge architectural configuration, artistic railing, lighting fixtures, and decorative elements will be developed from an integral concept that is complimentary wtih the adjacent Ave 19
Bridges and the proposed Confluence Park.
