The replacement of Los Angeles\u2019s Sixth Street Viaduct<\/strong> is a 3,500-foot-long cast-in-place concrete, network-tied, and through-arch bridge. The original Sixth Street Viaduct<\/strong> was also designed by local firm Michael Maltzan Architecture<\/strong> (MMA), and will directly connect the Boyle Heights neighborhood to Downtown Los Angeles in under a years time.<\/p>\n

Michael Maltzan<\/strong>\u00a0and HNTB Corporation<\/strong> created a replacement idea and design dubbed \u201cRibbon of Light,\u201d in 2012. They view it as a chance to transform an auto-centric piece of infrastructure into a community focused structure that represents the 21st-century values of connectivity and walkability.<\/p>\n

\u201cThe viaduct is more than a simple replacement thoroughfare crossing the Los Angeles River,\u201d noted MMA principal architect Michael Maltzan. \u201cIt foresees a multimodal future for Los Angeles, one that accommodates cars, incorporates significant new bicycle connections, and increases connectivity for pedestrians, not only at the bridge\u2019s endpoints, but along the entirety of the span, linking the bridge, the Los Angeles River, and urban landscapes below.\u201d<\/p>\n

\u201cThe new bridge is base isolated, allowing it to move independently from the ground below in the event of an earthquake,\u201d said MMA associate Paul Stoelting. \u201cThe base isolators are steel, triple-friction bearings, 6 feet in diameter and placed on top of each foundational shaft, which allow movement of 30 inches in any direction.\u201d<\/p>\n
