During a weekend shutdown of U.S. Route 101 in Los Angeles, crews began demolition of the 3,500-ft-long Sixth Street Viaduct to prep for the construction of a $449-million replacement. Popular with Hollywood movie producers for car-chase scenes, the 84-year-old iconic structure’s concrete suffers from chemical deterioration. The new cable-supported canted-arch bridge—designed by HNTB and architect Michael Maltzan—features a “ribbon of arches” that sweep up to 60 ft high. Joint-venture contractor Skanska-Stacy and Witbeck expect to complete demolition of the old structure in nine months and begin construction by late 2019. Script writers will need to make adjustments.
