Bridge and Bridge Construction

During the construction of the viaduct in the 1930s, an onsite plant was used to supply the concrete for construction. However, the quality of the concrete turned out to have a high alkali content and led to an (ASR), which created cracks in the concrete and sapped the strength of the structure. It is the only one of the historic L.A. River viaduct bridges to suffer from ASR.
