demolition work is set to start in los angeles, where a new viaduct will take the place of the original sixth street bridge built in 1932 — owing to deterioration caused by a chemical reaction in the concrete. designed by michael maltzan, the scheme also forms an urban park, uniting the boyle heights community to the east and the arts district and downtown to the west. the design is the product of an international competition led by the city of los angeles bureau of engineering

working alongside engineers HNTB, maltzan developed the design to accommodate a range of transport. consequently, the viaduct incorporates significant new bicycle connections, and also increases connectivity for pedestrian access, not only at its endpoints, but along the entirety of the structure.

the 3,500 foot (1,067 meter) viaduct is defined by ten pairs of repeated concrete arches, rising and falling along the north and south edges of the bridge as it extends from east to west. the arches incline outward from a deck, which is suspended from the cable lattice at its perimeter. below, the structure’s generous spans create large open spaces that form recreational green areas.

five pedestrian stairways along the length of the viaduct connect the bridge with the ground, a strategy that promotes a more significant degree of urban connectivity. under the eastern portion of the viaduct, a wide range of public activities occupy what was once a purely industrial zone. finally, a sloping path links the river to a future arts plaza at the terminus of the viaduct. construction work is underway as of february 2016, with the viaduct scheduled to complete in 2019.
