A $208 million improvement project for the Glendale-Hyperion Bridge is moving forward, bringing major upgrades to the nearly century-old span that connects Los Feliz, Silver Lake and Atwater Village. The improvements include seismic reinforcements, wider sidewalks and new bike lanes, while keeping the bridge open during construction. Officials say the improvements are designed to address years of safety concerns tied to the bridge's aging structure and constraints for pedestrians and cyclists navigating the corridor over the Los Angeles River and Interstate 5.
