In April, Mayor Villaraigosa and City Council Member Huizar announced an international design competition to redesign the historic, 80-year-old Sixth Street Bridge in Los Angeles. The decision to launch the competition came after engineers warned that the bridge was at risk of failing during a major earthquake due to a degenerative structural problem known as “concrete cancer”. After careful consideration and entertaining the idea of constructing a replica of the 1932 icon, the city committed to moving forward with a major redesign.

Announced in Washington DC the ARC jury of internationally-respected professionals with expertise in design, ecology, and engineering selected entry ‘hypar-nature’ led by HNTB with Michael Van Valkenburgh & Associates as the winner of the ARC International Design Competition.
The ARC Wildlife Crossing Competition challenged interdisciplinary design teams to create the next generation of wildlife crossing structures for North America’s roadways. The four inter-related objectives for the competition included:
- Provide an avenue for international teams of design professionals to address new design challenges in the coalescent issues of road transportation safety, structural engineering, wildlife conservation and landscape ecology;
- Explore creative new approaches, materials, and designs that address the fundamentals of transportation engineering and ecology;
- Increase the number of potential solutions for cost efficient, innovative crossing designs that can be adapted for widespread use in other locations; and,
- Engage design professionals and students in the interdisciplinary nature of road ecology with a real-time, in-situ application.
