Over the years, various costly restorative methods have been tried, but none have worked to correct the problem.
Constructed in 1932, the 6th Street Viaduct is an important engineering landmark in the City of Los Angeles. It is one of a set of fourteen historic Los Angeles River crossing structures. With an overall length of 3,500 ft. it is the longest of these structures. It is a critical east-west transportation link between LA Art District and Boyle Heights and has been determined to be eligible for listing in the National Register.
The concrete in the 6th Street Viaduct has been subject to a chemical reaction, known as Alkai Silica Reaction (ASR) causing significant deterioration of the structure./>
