Road Tripping USA – Episode 6
- 7000 km, two months and six US states. In early 2016 I traveled along the American west coast from north to south. This post is part of a series of articles created during this trip.
An icon. A landmark. Seen in countless movies, shows and music videos, the Sixth Street Bridge was an important and famous part the Los Angeles cityscape. The viaduct bridge connected the Arts District in Downtown Los Angeles with the Boyle Heights neighborhood. It traversed the Los Angeles River, the Santa Ana Freeway, the Golden State Freeway as well as Metrolink and Union Pacific railroad tracks and several local streets. Despite its historical status and huge popularity demolishing of the 1932 build bridge started in January 2016 due to structural problems. 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 alkali-silica reaction which creates cracks in the concrete and saps the strength of the structure.
While staying in Los Angeles during my 2016 US trip, I payed the historic bridge one last visit before it was demolished.
The new bridge, designed by architect Michael Maltzan and the HNTB Design-Build team, is set to be completed in 2019. City leaders are also looking into building parks and plazas around the newly built bridge.
