We join LABC in applauding HNTB for their forward-thinking plan, encompassing recreation, green technology, improved mobility, and community partnership.

The Sixth Street Viaduct Replacement Project earned a Design Concept Award at the 43rd Annual Los Angeles Architectural Awards, presented by the Los Angeles Business Council. HNTB Corporation will deliver final design and construction support services on the project for the City of Los Angeles Bureau of Engineering.

Winners of this year’s awards were announced at a ceremony hosted on June 5, 2013, in Beverly Hills, Calif. The first architectural awards of the season, this event honored the city’s most dynamic and beautiful architectural projects that include elements of commitment to environmental sustainability and community impact.

“Congratulations to HNTB for this outstanding achievement,” said City Engineer Gary Lee Moore. “We know first-hand the architectural brilliance this new Sixth Street Viaduct design represents, and look forward to seeing it come alive in our downtown and Boyle Heights communities. We join LABC in applauding HNTB for their forward-thinking plan, encompassing recreation, green technology, improved mobility, and community partnership.”

“To be recognized by the LABC is a tremendous honor for the City of Los Angeles, HNTB, Michael Maltzan and all the firms working together to bring this iconic new bridge to the people of L.A,” said Vic Martinez, HNTB project manager and Southern California office leader. “The new Sixth Street Viaduct is a rare transformative opportunity for this community that will improve mobility, enhance safety, stimulate investment and offer people a place to gather, recreate and connect.”

Construction is expected to start in 2015. The project, which will create nearly 5,000 jobs, is expected to be completed in late 2018 and opened in 2019.

HNTB led an intensive design collaboration of world-class consultants, including Maltzan, a noted Los Angeles architect, to craft the winning design, which features:

  • A “Ribbon of Light” design concept that draws inspiration from the original, early 1900s, family of Los Angeles River bridges and pays respect to the original viaduct;
  • The concrete structure includes 10 signature arches reaching from the Downtown Los Angeles Arts District, over the Los Angeles River to U.S. Highway 101, serving as an iconic gateway to Boyle Heights;
  • A new Viaduct Park that will increase the recreational green space available to Boyle Heights residents;
  • An Arts Plaza, on the Downtown Los Angeles side of the viaduct, that will be a dynamic urban gathering place and a catalyst for economic growth;
  • Bike and pedestrian access compliant with the Americans with Disabilities Act, and improved access to the Los Angeles River;
  • Pedestrian and bike access between the bridge and the parks and river beneath, anticipating the future restoration and enhancement of the Los Angeles river into an area of recreation and public use.
