Inscription. The 1st Street Viaduct over Glendale Boulevard is a reinforced concrete bridge with a box girder design constructed between 1940 and 1942. Designed by the City of Los Angeles Bureau of Engineering, the viaduct has Moderne-style architectural features integrated with smooth surfaces that show the influence of International Style Modernism. The reinforced concrete bridge section is 562 feet long and the entire structure, including approach spans and abutments, is 974 feet long, making the viaduct one of the largest road-to-road grade separations in Los Angeles dating from before the freeway system. The 1st Street Viaduct over Glendale Boulevard has been determined eligible for listing in the National Register of Historic Places as part of the Caltrans Statewide Historic Bridge Inventory. In 2017, the viaduct was seismically retrofitted with reinforced foundations and steel jackets at column bases. The bridge deck was widened by 2.5 feet on each side. The retrofit and widening necessitated the removal of the viaduct's distinctive railings, light poles, abutment pylons, railing caps, and stepped walls. The railings and light poles were salvaged and reused to the extent possible and replaced in kind when necessary. The pylons, railing caps, and stepped walls were reconstructed to match the original Art Moderne design.

Regarding 1st Street Viaduct. An excellent and rare example of a 1940s concrete bridge. The bridge was constructed to allow automobile traffic to pass over this busy intersection, bypassing a rail line

In 1941, the Works Projects Administration (WPA) built a viaduct to take First Street over the Pacific Electric interurban trolley tracks that ran along Glendale Boulevard at the time. The viaduct is still in use, though Pacific Electric disappeared long ago.
“Designed to eliminate a major traffic problem on the Northwest side of Los Angeles,” the caption to a WPA photo notes, “the First and Glendale viaduct, a $475,000 WPA construction project, is scheduled for completion, under city sponsorship, approximately July 15, 1941. A WPA crew of 270 workers are engaged on the job. The viaduct will carry First Street over the busy Pacific Electric tracks on Glendale Boulevard, thus eliminating a hazard and expediting westbound traffic.”
From 1939 to the end of the program in 1943, the WPA was known as the Works Projects Administration rather than the original name, Works Progress Administration.
