COWI completes iconic Los Angeles viaduct milestone
COWI North America celebrates an engineering milestone on the new 6th Street Viaduct construction in Los Angeles following the successful hanger installation of the first span out of 10 spans of the new viaduct.
Spanning across Freeway 101, several rail roads and the LA river, the 6th Street Viaduct replacement project is one of the largest bridge projects currently underway in the City of LA. Originally built in 1932, the iconic bridge – commonly recognized for its appearance in the hit movie-musical ‘Grease’ - provides a vital connection between Boyle Heights and Downtown LA’s Art District. In 2016, the bridge was demolished following the decision to replace the existing 6th Street Viaduct due to the structure becoming seismically vulnerable.
